The principle and function of hollow pin chain of agricultural machinery

Hollow pin chains are designed to reduce friction through the double curved arc of the chain, and are used where there is more power but slower running speeds, which is significantly superior to belt drives, such as pneumatic compressors. Hollow pin chains are used for conveying, single pitch, double pitch and long pitch are available. Attachment or cross bar can be inserted into any link of the chain without disassembling the chain.5. Sprocket Sprocket if wear occurs as shown in the following figure (left), the teeth A part will hang the whole bar, resulting in the whole hair...

Analytical chain drive system modeling

Modeling Chain Drive Systems Modeling the dynamics of a sprocket assembly, i.e., a chain drive system, is usually a difficult task for various reasons. In order to simulate a sprocket drive system, it is necessary to model all relevant components in the chain drive. However, since a typical chain drive consists of multiple links that are interconnected and wrapped around multiple sprockets, a significant amount of time is required to construct the geometry. 3D animated simulation of a chain drive system. Even if accurately built...

Share sprocket parameters

SPROCKET PARAMETERS In order for a chain rotation system to work properly, the sprocket and chain should be compatible with each other. To ensure this, the distance between the centers of adjacent teeth of the sprocket should be consistent with the pitch of the chain. Similarly, each sprocket tooth should be constructed so that it fits the sprocket. Also, the maximum width of the sprocket should be less than the clear distance between the internal link plates. If required, a parameter can be set to add some clearance between the sprocket and the chain plates. Some important parameters of a sprocket include: Pitch (p...

How to choose the number of teeth of large sprocket

Number of teeth of large sprocket = number of teeth of small sprocket X speed ratio After determining the number of teeth of small sprocket, multiply it by the speed ratio to determine the number of teeth of large sprocket. Generally speaking, the number of teeth of the small sprocket is 17 or more, 21 teeth at high speed, and 12 teeth at low speed, but the number of teeth of the large sprocket should not exceed 120 teeth. In addition, if the speed ratio is 1 : 1 or 2 : 1, select a sprocket with a large number of teeth as much as possible. For general use, set the speed ratio to 1 : 7 or less, preferably 1 : 5...

Introduction of several common gears such as spiral gears bevel gears

Spur Gears The most common gears are straight toothed cylindrical gears used for large gear reduction. The teeth on a spur gear are straight and mounted parallel on different shafts. Spur gears are used in washing machines, screwdrivers, wind-up alarm clocks, and other devices. Because gears mesh and collide, each impact makes a loud noise and causes vibration, which is why straight cylindrical gears are not used in machinery such as automobiles. A normal gear ratio ranges from 1:1 to 6:1. spiral...

Analysis of bevel gears in crushing equipment

All bevel gears have much in common in their design and manufacture, but those destined for use in pulverizers must have certain critical characteristics that are not standard since the automotive industry. As is often observed in the large bevel gear industry today, these critical characteristics are not widely understood in the engineering community, let alone in the much smaller number of gears for which manufacturers are expected to be fully aware of the technical requirements for these applications. For pulverizer applications, the gear's working shaft relies on plain bronze bushings...

TSH induction hardening process for sprocket gears

TSH technology is an advanced induction hardening process specifically designed to reduce overall costs and replace chemical heat treatment processes. Conventional heat treatment of sprocket gears consists of prolonged gas carburizing in batch or continuous furnaces followed by oil quenching. Typically, the gears are tempered in a low-temperature furnace for one hour. After carburizing, the gear surface area typically has a carbon content in the range of 0.7-1.0% C and a hardness in the range of 58-63 HRC. post-treatment includes grinding and shot peening to improve fatigue strength...

Maintenance of agricultural machinery chain sprockets

1. The sprocket wheel should be mounted on the shaft without skewing and swinging. The end faces of two sprockets in the same transmission assembly should be located in the same plane, and when the center distance of the sprockets is below 0.5m, a deviation of 1mm is allowed; when the center distance of the sprockets is above 0.5m, a deviation of 2mm is allowed. However, it is not allowed to have the phenomenon of friction on the teeth side of the sprocket wheel, if the two wheels are shifted too much, it is easy to produce off the chain and accelerate the wear. When replacing the sprocket, we must pay attention to checking and adjusting the offset. 2, the tightness of the chain should be appropriate, too...

摩托车链条,链轮的更换也是有讲究的,首先链条和链轮一定要同时更换,因为它们处于同一个工作状态,只有一起更换它们的间隙才能保证正常,不然单个更换就会缩短使用寿命。 其次,它们的抗磨损性和抗拉能力一定要一致,不然就会加速磨损,而保证这两项一致的最好办法就是更换套链,套链的制造工艺和抗磨性能都会好于,配装…

What material is usually used for scraper conveyor sprockets?

链轮组件是刮板输送机的动力驱动的关键部位,其耐磨性和强度决定着整个综采工作面的工作效率。而耐磨性和强度是由材质和热处理方式来决定的。 由链轮的工作环境可知,链轮和链条摩擦主要发生在链窝处,因此链窝处的淬火硬度和淬硬层深度至关重要。对于42CrMo和40CrNiMoA材质的链轮,两种材质齿内面及链窝轮廓淬火硬度都能…
