Anyone who has dealt regularly with mechanical will know that theSpeed ReducerIs an essential auxiliary equipment in some machinery, because some machinery running fast will be dangerous, so you need to use the reducer to balance its speed of movement, however, in the use of the reducer in the process, causing the reducer string axle from the following three points to grasp the reason.
1, is due to broken teeth so that the input shaft loses axial constraints and crosstalk occurs, the intermediate shaft of the driven gear and shaft fastening is not secure. In the actual transmission, often due to the follower gear and intermediate shaft between the amount of interference is not enough, the follower gear relative to the intermediate shaft to produce axial crosstalk, and then make the input shaft axial crosstalk. Therefore, the interference is not enough to cause the main reason for the reducer crosstalk. In addition, the steering of the reducer also has a certain impact on the crosstalk.
2, gear processing skew caused by crosstalk. Skewed processing of the driven gear on the intermediate shaft can cause crosstalk. Gear processing is outside the circle and end face for positioning, and gear assembly is within the hole positioning, sometimes the hole and the outer circle is not concentric, or the hole and the end face is not perpendicular to the processing of the gear and the hole centerline skew. This skewed herringbone gear, the plane where its centerline is not perpendicular to the axis, when the gear rotates for a week, a point on the centerline will occur axial reciprocating crosstalk once, forcing the input shaft also axial reciprocating crosstalk once. In the actual transmission, due to the two halves of the follower gear skewing degree is different, for the input shaft, axial crosstalk is the intermediate shaft on the two halves of the follower gear skewing degree of the results of the combined effect. In addition, the output shaft of the driven gear, due to gear processing skew is also the same cause of crosstalk, but because the output axis is fixed in the axial direction, forcing the intermediate shaft to move, which in turn forces the input shaft crosstalk.
3, gear helix angle error caused by crosstalk. Intermediate shaft and output shaft on the two halves of the slave herringbone gear, due to the actual helix angle error, will make the herringbone gear changes in the center line, resulting in crosstalk. ③ reducer to withstand positive and negative torque, tooth thickness error, uneven wear and premature wear of the tooth surface, tooth back deformation caused by crosstalk.
