Abstract

The invention discloses a speed reducer with planetary gears and a cycloidal gear. The speed reducer comprises an input gear shaft, the planetary gears meshed with the input gear shaft, pin shafts arranged inside inner holes of the planetary gears, roller pins positioned between the pin shafts and the planetary gears, a crankshaft, a planetary carrier end cover, cushion columns, an outer gear ring, a casing, the cycloidal gear, a transmission component and an output end, wherein the crankshaft and the planetary carrier end cover are respectively connected with the two ends of the pin shafts; the cushion columns are positioned between the crankshaft and the planetary carrier end cover; the outer gear ring is positioned on the outer rings of the planetary gears and meshed with the planetary gears; the casing is fixedly connected with the outer gear ring; the cycloidal gear sleeves the eccentric circle of the crankshaft through a cylindrical roller bearing B; the transmission component is clamped with the cycloidal gear; the output end is clamped with the transmission component. The speed reducer has the advantages of being high in precision, high in transmission efficiency, simple in structure, small in size, convenient to mount, and low in manufacturing cost.

Description

Technical field: [0001] The present invention relates to the technical field of mechanical transmission, and more specifically relates to a speed reducer. Background technique: [0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. Planetary cycloidal gear reducers are widely used in many fields such as robots, CNC machine tools, medical equipment, and national defense because of their excellent performance. The existing planetary cycloidal gear reducers all adopt two or more cycloidal gear-crankshaft structures, which not only have a complex structure, but also take up a large space, are also cumbersome to install, and are quite inconvenient to use. Invention content: [0003] The purpose of the present invention is to provide a planetary cycloid gear reducer which has the advantages of high precision, high transmission efficiency, simple struct...
