Universal speed reducer of sliding gear meshing pair

Abstract

The invention discloses a universal speed reducer of a sliding gear meshing pair, which comprises a shell, a power input shaft and a power output shaft, wherein the power input shaft is provided with an eccentric sleeve; the power output shaft is provided with a sliding gear disk; the sliding gear disk can be radially provided with a sliding gear in a single-freedom degree sliding way; a gear groove is fixed to the shell, is concentric with the power input shaft and can be in small tooth difference meshing with the sliding gear; the width of the gear groove along the circumference direction is larger than the gear thickness of the sliding gear along the circumference direction; and the eccentric sleeve is opposite to the sliding gear along the axial direction and is internally sleeved into the sliding gear disk eccentrically. A pressure angle of the invention can be adjusted by changing the eccentric amount of the eccentric sleeve; a pressure angle of a conjugate gear can be reduced from 60 degrees or so to 25 degrees, thereby preventing power consumption caused by an overlarge pressure angle, greatly improving the drive efficiency and smoothly outputting motion without blockage; and the reduction ratio can be fitted by the quantity of the gear grooves, the drive ratio range can be expanded to 5 to 50, and the invention has the advantages of simple design, small structure size, few parts and low processing cost.

Description

technical field [0001] The invention relates to a deceleration device, in particular to a universal decelerator with sliding teeth and meshing pairs. Background technique [0002] The reducer is a device that reduces the high speed of the power machine to the speed suitable for the working machine, and is widely used in the equipment industry. With the development of the equipment industry, higher requirements are put forward for the reducer. The multi-stage gear reducer is widely used in the prior art. The multi-stage gear reducer uses multiple sets of gear meshing pairs to fit the transmission ratio. When the reduction ratio is required to be slightly larger, its structure is complicated and the volume is also large; The gear reducer can obtain a large reduction ratio, but it needs to arrange multiple sets of gears and gear shafts in the radial direction, the structure is relatively complicated, and the structural arrangement is difficult and the volume is large.

AI Technical Summary

Problems solved by technology

Due to the cycloidal wheel in the prior art has two kinds of motions, revolution and rotation, part of the motion cannot be used for transmission, resulting in useless high-frequency waves, motion interference or other additional motions, resulting in the transmission of the small tooth difference reducer. The efficiency is low or the power cannot be output
