Soft starting hoisting gear for two stage planetary gear train transmission

Abstract

The present invention provides the technological scheme of soft started winch with two stages of transmission planet gear train. The technological scheme includes one motor, one planet gear transmission mechanism, and one brake. It features the planet gear transmission mechanism including one first planet gear transmission mechanism and one second planet gear transmission mechanism; the successive connection of the motor output shaft, the first planet input shaft and the first planet central gear; the successive connection of the first planet carrier, the second planet input shaft and the second planet central gear; the second planet carrier connected to the output shaft; the successive meshing of the second planet casing ring gear, the transition gear and the braking gear; The braking shaft connected to the water cooled disc brake; and the coaxiality of the motor output shaft, the first planet input shaft, the second planet input shaft and the output shaft.

Description

Technical field: [0001] The invention relates to a mine transportation mechanical equipment, in particular to a soft start winch driven by a two-stage planetary gear train. Background technique: [0002] In the prior art, the well-known technology is the patent No. 200520081476.9, which the applicant applied for and authorized to be published in the State Intellectual Property Office. This patent discloses a technical solution of a planetary controllable starting transmission device. The brake is connected to the planetary transmission mechanism and the brake is used to achieve soft start performance, but the brake used is a conventional natural cooling disc brake. This kind of self-cooling brake disc will generate heat during braking, which is serious. Sometimes overheating or even sparks will occur, which directly affects the application in industries such as chemical industry, coal, petroleum, etc., and the scope of use is limited to a certain extent, which is the weak po...

[0002] In the prior art, the well-known technology is the patent No. 200520081476.9, which the applicant applied for and authorized to be published in the State Intellectual Property Office. This patent discloses a technical solution of a planetary controllable starting transmission device. The brake is connected to the planetary transmission mechanism and the brake is used to achieve soft start performance, but the brake used is a conventional natural cooling disc brake. This kind of self-cooling brake disc will generate heat during braking, which is serious. Overheating or even sparks will occur when the battery is used, which directly affects the application in chemical industry, coal, petroleum and other industries, and the scope of use is limited to a certain extent. This is the deficiency of the existing technology.
