Gearbox production precautions
Oct 31, 2018

The gearbox is an indispensable device in engineering because the gearbox is a speed, energy transfer device.

 

The working principle of the gearbox, the speed increasing gearbox is driven by the motor with a large pulley. The motor power requirement is 65KW, and the highest speed is 132rpm. The large pulley drives the small pulley through the belt, and the drive is mounted on the same shaft as the small pulley. Gears and large gears drive the pinion to increase speed. High-speed bearings are the key factor in determining whether a gearbox can work properly, so the choice of bearing is critical to the gearbox.

 

The selection of gearbox gears is also very important. The materials of the gears used in general compressors are generally made of quenched and tempered steel 40Cr and the hardness is HRC54. The gear tooth surface made of this material has high contact strength and good wear resistance due to impact load. The important gear drive. The pinion number is selected as 15. The modulus is 2, the number of gears of the large gear is 225, the design accuracy of the gear is set to 4, and the machining accuracy is at least 5 levels.

 

At the same time, in order to ensure the minimum operating requirements of the gearbox, according to the shape of the box and the actual situation of the design, the position tolerance of the box at the time of design is 4 levels of precision, and the precision must be above 5 when processing.

 

The design of the gearbox is reasonable and the operation is stable, but there are some notable problems in the design, manufacture and operation. Therefore, the gear machining must ensure the necessary precision, otherwise the gearbox will generate huge noise and reduce the operation. The service life of the bearing can result in irreparable damage to the gearbox. When using a V-belt, care must be taken to ensure that the diameter of the small pulley is large enough to meet the minimum requirements for the angle of the belt to be used. Otherwise, there will be a jump belt and a slip phenomenon, and the speed and power transmission tasks cannot be completed.
