Spiral bevel gears, straight bevel gears, bevel gears, their differences

1, straight bevel gear is a kind of most basic bevel gear, the processing is simple, but the transmission accuracy is too poor, instantaneous transmission than not, just as General de change the direction of transmission, institutions than does not have strict requirement on the speed and transmission, such as shaper workbench lifting, operating shaft, suitable for low velocity bodies.

2, bevel gear is in straight bevel gear based on the modified type, relative to the straight bevel gear of some disadvantages have been improved, such as: instantaneous transmission ratio is relatively accurate, high transmission precision a little, transfer efficiency is higher than that of the straight bevel gear, popular to say, compared with straight tooth bevel gear, drive to the relaxed a little, but mesh adaptation will due to the reasons for making very good grasp the best and suitable in speed is not too high institutions, and the need to lubricate.

3, the efficiency of spiral bevel gear is best, performance parameters of the best, at the bottom of the automobile drive shaft and the bridge [tooth pack] (is the bridge in the middle of the circular), which will have a set of spiral bevel gear pair, the performance are as follows:

Has the advantages of high transmission efficiency, low friction resistance, instantaneous transmission ratio, accurate transmission torque, especially suitable for high-speed transmission

Disadvantages: high cost, due to manufacturing and installation, the coincidence degree is difficult to grasp the best, need good lubrication, oil bath lubrication is the best
