High-efficiency energy-saving hoist gear change device for vessel

Abstract

The invention relates to a high-efficient energy-saving winding speed adjusting device, comprising a sun wheel, a planet carrier and a planet wheel. One end of the sun wheel is vertically arranged in an annular gear of the planet carrier; the planet carrier is connected with the planet wheel through a planet shaft by a bearing; the outer diameter of the sun wheel is processed into a full-length tooth part; the outer diameter of one end of the tooth part is processed into two spaced clamping spring grooves; the planet carrier is a single-leaf disc-shape forged member. The outer diameter of the sun wheel of the device leaves out the processing of a tool recess and a two-tooth part; the processing technique is simplified, the cost is lowered, the size of the overall speed adjusting device is reduced; the noise of transmission is lowered and the efficiency and reliability are improved to a large extent.

Description

technical field [0001] The invention relates to a speed change device, in particular to a marine high-efficiency and energy-saving winch speed change device. Background technique [0002] The planetary gear transmission of the existing speed change device, the connection between the sun gear and the planet carrier, the sun gear is made into two tooth parts a and b, and a sufficient distance is left between the tooth part a and the tooth part b as the tool relief groove c, and the knife retraction The diameter of the groove part is restricted by the gear parameters of the two tooth parts and cannot be too large, so the undercut groove c is easy to break, and the overall strength is affected; because the tooth part a and the tooth part b are two tooth shapes, the tooth part a requires Gear hobbing-carburizing and quenching-grinding, while the tooth part b only requires gear shaping, the processing technology of the two tooth parts is different, it is difficult to control the d...
