Abstract

The invention discloses a planet wheel inner hole drum-shaped raceway machining device. According to the planet wheel inner hole drum-shaped raceway machining device, a guide frame is mounted on a supporting frame, a sliding groove is formed in the bottom of the guide frame, and two sliding blocks are arranged in the sliding groove in a conformal sliding fit mode. A first grinding machine and a second grinding machine are respectively arranged on one sliding block. A first grinding wheel is connected to the first grinding machine, a second grinding wheel is connected to the second grinding machine, and the horizontal plane where the bottom end face of the first grinding wheel is located and the horizontal plane where the top end face of the second grinding wheel is located are located at the same horizontal plane. A driving mechanism is used for driving the first grinding machine and the second grinding machine to transversely move close to or away from each other. According to the planet wheel inner hole drum-shaped raceway machining device, the driving mechanism is connected with the two sliding blocks, the first grinding wheel and the second grinding wheel can move to the designated grinding position, and therefore the machining precision of the first grinding wheel and the second grinding wheel on the inner wall of a planet wheel is improved, and close fit between an innerhole raceway of the planet wheel and a roller is facilitated.

Description

technical field [0001] The invention relates to the technical field of planetary wheel processing, in particular to a device for processing a drum-shaped raceway in the inner hole of a planetary wheel. Background technique [0002] In the field of gear transmission technology, the planetary gear transmission with hard tooth surface has the characteristics of large speed ratio, small size and high load capacity. It has been widely used in important industrial sectors such as wind power generation, metallurgy, and building materials, especially in the wind power generation industry. 70% of the world's wind power generators' main speed-up gearboxes use planetary gear transmission. With the rapid development of wind power generation technology in the world, the transmission power of the planetary gear transmission is increasing, which has reached 5 megawatts at present, and the reliability requirements are higher. [0003] In order to meet the harsh working conditions of the wi...
