Helical gear reducers are specialized reducers for various reaction vessels. Their gears utilize Gleason hypoid tooth profiles and have hardened tooth surfaces, offering advantages such as high load capacity, low noise, long lifespan, high power, and smooth operation. The overall performance is far superior to cycloidal pinwheel reducers and worm gear reducers. Helical gear reducers are driven by a V-belt, with the input section rotated by a motor via the belt. Standard V-belts are standard at the factory; however, when using explosion-proof motors, anti-static V-belts should be used. Helical gear reducers are space-saving, reliable, durable, and have high overload capacity, with power up to 200KW. They are energy-efficient, have superior performance, a reduction efficiency of over 95%, low vibration, low noise, and a rigid cast iron housing. The gear surfaces undergo high-frequency heat treatment and precision machining to form helical gears and bevel gears. This is a brief overview of the characteristics of helical gear reducers. We hope that when using helical gear reducers, you can consider their features…

There are generally three methods for emergency braking of speed reducers: mechanical braking, regenerative braking, and reverse braking. Reverse braking offers the fastest braking speed. Below are the requirements for this braking method: 1. To effectively address the problem, it's necessary to understand the characteristics of the speed reducer's load and the specific requirements of its use. 2. The microcontroller-controlled motor drive circuit needs to have a power reverse function, such as a bridge circuit composed of four transistors or a forward/reverse circuit composed of relays. 3. When braking is required, the control circuit short-circuits to switch to motor reverse mode. When the motor speed drops to 0, power is cut off to reverse the circuit, and the motor stops. It's important to note that due to load variations, the time required for the reverse circuit to reduce the motor speed to 0 is not constant. Additionally, the speed reducer needs to be equipped with a speed sensor; otherwise, more complex control techniques, such as adaptive control, are required. You need to master these techniques for specialized applications…

We often buy gear reducers because they are technologically advanced, space-saving, energy-efficient, high-performing, with low vibration and noise, and excellent energy saving. However, sometimes things aren't as perfect as we imagine. Gear reducers can become quite noisy over time, a problem we cannot ignore. The noise from gear reducers clashes with today's environmental protection standards. The noise is caused by the friction and collision between the gears, so it's necessary to take measures to address it. Applying lubricant between the gears can reduce friction and collision, thus minimizing noise. This is a common and effective method.

How to install a shaft-mounted geared motor. This section primarily discusses three aspects: the installation relationship between the shaft-mounted geared motor and the working machine, the connection between the shaft-mounted geared motor and the working machine, and the installation of the reaction torque bracket. Below, Shanghai Gearbox will describe the installation process in detail. I. Installation Relationship between Shaft-Mounted Geared Motor and Working Machine: To prevent deflection of the working machine's main shaft and additional forces on the gearbox bearings, the distance between the gearbox and the working machine should be as small as possible, ideally 5-10mm, without affecting normal operation. II. Connection between Shaft-Mounted Geared Motor and Working Machine: The gearbox is directly mounted on the working machine's main shaft. When the gearbox operates, the reaction torque acting on the gearbox housing is balanced by a reaction torque bracket mounted on the gearbox housing or by other methods. The gearbox is directly fitted to the working machine, with the other end connected to a fixed bracket. III. Installation of the Reaction Torque Bracket: The reaction torque bracket should be installed on the working machine facing the gearbox…

Gearbox wear is one of the most frequently asked questions by GM's technical staff. Regarding wear issues in planetary gearboxes, hardened gearboxes, and gear reducers, GM believes that proper oil changes and after-sales service are effective preventative measures. Taking gearbox oil changes as an example: the first oil change should be performed after 200-300 hours of operation. In subsequent use, the oil quality should be checked regularly, and any oil contaminated with impurities or deteriorated should be replaced promptly. Generally, for gearboxes operating continuously for extended periods, the oil should be changed every 5000 hours or annually. For gearboxes that have been out of service for a long time, the oil should also be changed before restarting. Gearboxes should use oil of the same brand as the original manufacturer's oil; mixing with oils of different brands is prohibited. Oils of the same brand but different viscosities can be mixed. When changing the oil, wait until the gearbox has cooled down to a point where there is no risk of combustion, but it should still be kept warm, as the oil will…

What are the causes of oil leakage in T-series steering gearboxes? 1. Inadequate structural design. During manufacturing, if the castings are not annealed or aged, internal stress will not be eliminated, inevitably leading to deformation and voids, resulting in leakage. 2. Pressure difference between internal and external parts. During operation, the moving parts generate heat due to friction, and the ambient temperature also affects the steering gearbox temperature. If there is no vent or the vent is blocked, the internal pressure gradually increases. The higher the internal temperature, the greater the pressure difference with the outside, causing lubricating oil to leak from the gaps under the pressure difference. 3. Excessive oil filling. During operation, the oil sump in the T-series steering gearbox is violently agitated, and lubricating oil splashes everywhere inside the machine. If too much oil is added, a large amount of lubricating oil accumulates at the shaft seals and mating surfaces, leading to leakage. 4. Inadequate shaft seal design. Poor contact between the journal and the seal causes the seal to fail quickly. 5. Lack of an oil return groove on the gearbox body. Lubricating oil…

For a long time, my country's domestically produced cycloidal pinwheel reducers and gear reducers have become increasingly mature. Reducers are the most commonly used transmission equipment in the machinery industry. The new type of reducer has upgraded its power and transmission connection from traditional shaft connectors to specially designed spline connections using imported and assimilated foreign technology. The concentricity, parallelism, and precision of its core components have reached world-leading levels. Compared with similar domestic equipment, this new equipment saves one-third of metal materials, reduces volume by one-third, lowers noise by more than 100 decibels, increases efficiency by more than 60%, and costs only one-third of similar equipment on the international market. Reducers are widely used transmission and speed regulation devices in the major equipment manufacturing industry, and are widely used in many fields of the national economy, including modern scientific research, national defense, transportation, metallurgy, chemical industry, and infrastructure construction. Cycloidal pinwheel reducers and helical gear reducers are mostly general-purpose products, and people often…

I. Environmental Conditions 1. The temperature rise measurement of the cycloidal pinwheel reducer should be conducted indoors, unaffected by external temperature. The indoor ambient temperature should be within the range of 5~40℃, and the indoor air should circulate freely; forced circulation is not permitted. 2. Temperature Measurement Point The temperature measurement point should be selected where the thermometer can contact the lubricating oil of the cycloidal pinwheel reducer. II. Thermometer Scale Value: 0.5℃ III. Measurement Method 1. Determination of Operating Temperature The temperature rise measurement of the reducer under test is generally carried out together with the load-bearing capacity and transmission power measurement of the reducer, but it can also be carried out independently. When the reducer under test meets the requirements, read the operating temperature of the reducer at the rated speed and rated input power. 2. Determination of Ambient Temperature Place the thermometer 1.5m away from the surface of the cycloidal pinwheel reducer under test. The height of the thermometer measuring point from the ground should be equal to the height of the reducer's axis. The placement of the thermometer should not be affected by external radiant heat or airflow…

Abnormal noise from a hardened gear reducer is definitely caused by an anomaly. After ruling out uneven placement, the remaining issue is an internal fault. Let's examine the causes and solutions one by one: I. Causes of Abnormal Noise from Hardened Gear Reducers ① Coupler Damage. When the coupler connecting to the hardened gear reducer is damaged due to oil leaks, loose screws, etc., it will cause vibration and noise. ② Loose Motor Screws. Similar to coupler malfunctions, when the motor vibrates for various reasons, it will transmit the vibration to the reducer, increasing the reducer noise. ③ Severe Bearing Wear; Gear Damage. Gear damage includes severe pitting on the tooth surface, large gear meshing clearance, severe gear tooth wear, and broken teeth. These conditions of gear wear can all cause noise due to excessive vibration. ④ Shaft Deformation and Imbalance. When the shaft's strength and hardness are below requirements or due to aging from long-term operation…

Worm gear reducers consist of an input worm and an output worm wheel. Their characteristics include high torque transmission, high and large reduction ratios (ranging from 5 to 100 for single-stage transmissions), and non-coaxial input and output transmission mechanisms, making them difficult to use and resulting in the lowest transmission efficiency, not exceeding 60%. Because they are relative sliding friction transmissions, worm gear reducers have slightly lower stiffness values, and their transmission components are prone to wear and tear, leading to a short service life and temperature rise. Therefore, they have a limited allowable input speed (2,000 rpm), which restricts their application. Assisting servo motors in increasing torque: The development of servo motor technology, from high torque density to high power density, has increased speeds above 3000 rpm. This increased speed significantly improves the power density of servo motors. This means that whether a servo motor needs a speed reducer depends primarily on the application requirements and cost considerations…
