Speed reducing machine adopting air cylinder for driving main shaft to realize telescopic moving

Abstract

The invention discloses a speed reducing machine adopting an air cylinder for driving a main shaft to realize telescopic moving. The speed reducing machine comprises a speed reducing box (1), a cylinder tube (2), a spline shaft (3), an air cylinder (4) and a movable connecting device, wherein one end of the cylinder tube (2) is arranged on the speed reducing box (1) and is communicated with the speed reducing box (1), the movable connecting device consists of a slide block (7), a first baffle plate (8) and a second baffle plate (9), the spline shaft (3) sequentially passes through the speed reducing box (1) and the cylinder tube (2), a shaft sleeve (12) is arranged on the spline shaft (3) through a spline, and is rotationally arranged in the speed reducing box (1), a worm wheel (13) arranged in the speed reducing box (1) is rotationally arranged on the shaft sleeve (12), two connecting rods (16) are arranged on the rotating shaft (15), and a clutch (17) is arranged between the spline shaft (3) and the worm wheel (13). The speed reducing machine has the beneficial effects that the operation is simple, the free telescopic effect of the spline shaft can be realized in the operation process, and the long-distance torque transmission can be realized.

Description

technical field [0001] The invention relates to a reducer whose main shaft is telescopically moved by a cylinder. Background technique [0002] The reducer plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. [0003] At present, most of the output spindles of deceleration are axially fixed in the reduction box, and the shaft head of the output spindle of the reducer is equipped with a driving gear, and the driving gear must be meshed with the driven gear on the actuator to drive The torque of the prime mover is transmitted to the actuator, and th...

Problems solved by technology

[0003] At present, most of the output spindles of deceleration are axially fixed in the reduction box, and the shaft head of the output spindle of the reducer is equipped with a driving gear, and the driving gear must be meshed with the driven gear on the actuator to drive The torque of the prime mover is transmitted to the actuator, and the actuator can work normally. However, some actuators need to change their positions due to working conditions, resulting in a change in the distance between the actuator and the reducer. The reducer has to be moved to achieve matching. However, the size and weight of the reducer is large, which undoubtedly increases the labor intensity of the employees, and after moving the reducer, it needs to be re-matched with the driven gear on the actuator, which undoubtedly reduces production efficiency and affects the economy of the enterprise. benefits, therefore, this reducer is not promoted for use
