Abstract

The invention discloses an ultralow-speed-ratio, high-rigidity high-precision cycloidal-pin wheel planetary transmission speed reducer, and belongs to the field of mechanical transmission devices. Three spline gear assemblies are evenly arranged on the input planet carrier in the circumferential direction, the gear end of the spline gear shaft is arranged in the input planet carrier, and the planet gear is installed at the shaft end of the spline gear shaft, located outside the input planet carrier and used for being in meshing transmission with an external input gear to form first-stage transmission; a crankshaft gear assembly comprises a crankshaft, a center gear and a cycloidal gear, wherein the center gear and the cycloidal gear are sequentially installed on the crankshaft; the central gear is in meshing transmission with the gear end of the spline gear shaft to form second-stage transmission; and the crankshaft drives the cycloidal gear to be meshed with the roller pin in the pin wheel housing to form third-stage transmission, and the cycloidal gear drives the planet carrier to achieve power output. The first-stage transmission and the second-stage transmission adopt the structure that the same planet gears are uniformly distributed in the circumferential direction of the central gear, so that the whole machine is extremely compact in arrangement and high in transmission power, and the three-stage transmission has an ultra-low speed ratio.

Description

technical field [0001] The invention belongs to a mechanical transmission device, in particular to an ultra-low speed ratio, high rigidity and high precision cycloid planetary transmission reducer. Background technique [0002] Cycloidal pin wheel planetary reducer is mainly composed of four parts: planetary carrier, planetary wheel, center wheel and output mechanism. The input shaft and the eccentric sleeve fixedly connected to the input shaft constitute the planet carrier of the planetary transmission. The whole machine has the advantages of large transmission ratio, simple structure, small size, high efficiency, long service life, stable transmission, and high carrying capacity. [0003] When the cycloidal pin wheel planetary reducer is used in a lower transmission ratio range, and the cycloidal wheel adopts the traditional "one-tooth difference" tooth shape, the number of meshing teeth for effective force transmission is reduced at the same time, the load-carrying capac...
