Fixed-axis cycloid transmission device

Abstract

The invention discloses a fixed-axis cycloid transmission device comprising a shell, a power input shaft and a power output shaft. The power input shaft and the power output shaft are coaxially arranged and are respectively in rotation match with the shell; a driving disk is arranged in eccentric transmission match with the excircle of the power input shaft; a power output disk is arranged in transmission match with the power output shaft; transmission pins are uniformly arranged in rotation match along the circumference direction of the driving disk to form a pin gear which is engaged with an involute inner gear fixedly arranged on the shell; and the transmission pins are in eccentric rotation match with the power output disk. In the fixed-axis cycloid transmission device, the bearing capability of a cycloid reducing mechanism is enhanced, and a cantilever pin output mechanism of a traditional pin gear reducer is not used any nore, and power is directly output by the power output disk driven by the revolution motion of the transmission pins so as to enhance the transmission rigidity, improve the transmission efficiency and the transmission stability and further improve the bearing capacity. The invention has simple structure, small size, light weight, low cost, simplified mounting and dismounting processes and improved working efficiency.

Description

technical field [0001] The invention relates to a reduction transmission mechanism, in particular to a fixed-axis cycloid transmission device. Background technique [0002] The field of reduction transmission device includes ordinary cylindrical gear reducer, planetary gear reducer, worm gear reducer, cycloid reducer, harmonic reducer and movable tooth reducer according to different application requirements, among which cycloid reducer has It has the advantages of simple structure, small size, large transmission ratio, strong carrying capacity and high efficiency. [0003] The cycloidal pinwheel reducer includes an input part, a deceleration part, and an output part; the input shaft is an eccentric shaft (or eccentric bearing, eccentric sleeve), and the center hole of the cycloidal wheel is sleeved on the eccentric shaft and meshed with the pinwheel to form a deceleration mechanism , when the input shaft rotates with the eccentric sleeve, because the motion of the cycloid w...
