Embodiment Construction

[0009] Cam-type backlash-free precise positioning reducer includes cam 1. cam roller 2. turret 3. motor 4. encoder 5. Cam 1. and motor 4. are linked to drive the cam roller 2 to rotate one circle. It moves along the motion curve of the cam, driving the turret to move along the curve of the cam 1. to move an angle, and the continuous rotation of the cam 1 drives the turret 3. Doing continuous circular motion, when the cam 1. rotates in the opposite direction, since the cam 1. and the cam roller 2. are meshed without backlash, the motion track of the cam 1. is transmitted to the turret 3 without error. The cam is connected with the motor, and the encoder is connected with the cam to control the rotation angle of the turret, so as to complete the precise positioning of the backlash-free transmission.

Abstract

The invention discloses a cam-type backlash-free precision positioning speed reducer. An input end cam is in occlusion with cam rollers radially embedded on the circumferential surface of an output end turret; the cam rollers drive the output end turret to rotate when the input end cam rotates to drive the moving of the cam rollers according to set displacement curve; the speed reducer driven by amotor can be produced through the backlash-free occlusion of the input end cam and the output end turret; and an encoder links the cam to control the rotation angle of the turret.

Description

technical field [0001] The invention relates to a reducer device, in particular to a cam-type backlash-free precise positioning reducer for transmission positioning. Background technique [0002] Existing reducers usually work in the form of gears, that is, use one gear to mesh with another gear through involute, and achieve the purpose of deceleration through the gear ratio. Since the gears are involute meshing transmission, when the gear When the direction of rotation changes, there is an occlusal gap. Backlash-free transmission cannot be realized, and precise positioning cannot be achieved. Contents of the invention [0003] In order to overcome the gaps in the gear meshing transmission in the prior art, the positioning accuracy is low, and there is backlash and other defects, the present invention provides a cam-type backlash-free precise positioning reducer. The cam installed at the input end is connected to the turret at the output end. , to radially embed the cam r...
