Abstract

The invention provides a cycloidal planetary reducer and a mechanical equipment tool. The cycloidal planetary reducer comprises a pin gear housing, a cycloidal gear, an input shaft, a crankshaft and a planetary carrier, wherein gear teeth of the cycloidal gear are engaged with pin teeth in the pin gear housing; the pin teeth are strip-shaped convex teeth which are arranged on the inner wall of the pin gear housing, and the strip-shaped convex teeth and the pin gear housing are formed integrally; a planetary gear on the crankshaft is in engaging transmission with a driving gear on the input shaft; an eccentric shaft is arranged on the crankshaft, and a first bearing is arranged between the eccentric shaft and the wall of a hole of the input shaft; the planetary carrier is connected to the pin gear housing in a supported mode through a second bearing; and the crankshaft is connected to the planetary carrier in a supported mode through a third bearing. By adoption of the technical scheme, the technical problem that in the prior art, gap inevitably exist between pin teeth and a pin gear housing in an ordinary cycloidal planetary reducer due to the assembling structure between the pin teeth and the pin gear housing, the manufacturing precision and other factors, and consequentially vibration and noise are generated in the transmission process is solved.

Description

technical field [0001] The invention belongs to the technical field of equipment manufacturing, and more specifically relates to a cycloidal planetary reducer and mechanical equipment tooling. Background technique [0002] In the current equipment manufacturing industry, the cycloidal planetary reducer has excellent performances such as large transmission ratio range, high motion precision, small hysteresis, high rigidity, strong impact resistance, small size, compact structure and high transmission efficiency. Widely used in robotics, CNC machine tools and automation equipment and other fields. [0003] At present, the mainstream cycloid reducer has the following disadvantages: (1) Since the pin teeth rotate in the inner groove on the pin gear housing, during the transmission process, there is pure sliding friction between the pin teeth and the pin gear housing, Therefore, the machining accuracy of the outer surface of the pin tooth and the inner groove of the pin gear hou...
