Drum support transmission system for hoisting mechanism

Abstract

The invention relates to a reel support transmission system for a hoisting mechanism, which includes a reel support part, a parallel shaft reduction box part and a planetary transmission part; The ring is integrated with the box of the parallel shaft gearbox, and the outer ring of the needle bearing is integrated with the reel; the parallel shaft gearbox part adopts three-stage hard tooth surface helical gear transmission, and the parallel shaft gearbox part is Motor interface; the planetary transmission part is fixed by the planet carrier, the ring gear of the planetary transmission part is in interference fit with the reel, the input end of the planetary transmission part is the sun gear located in the center of the reduction box, and the output end of the planetary transmission part is installed on The ring gear on the reel and the sun gear of the planetary transmission part are connected with the output shaft of the parallel shaft reducer; the structure design is simple, and it has the advantages of small size, large speed ratio, superior performance, and easy assembly.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a drum support transmission system for a hoisting mechanism. Background technique [0002] The hoisting mechanism of a traditional crane is the core component of the crane, which is a key component related to the performance and main parameters of the crane. At present, the transmission of the reel of the lifting mechanism at home and abroad is mainly that the output shaft of the reduction box is directly connected with the reel through the reel coupling or spline (gear). The reel support of the domestic lifting mechanism is divided into two forms: one It is directly supported by the output shaft bearing of the gearbox, which requires the bearing of the gearbox to have sufficient carrying capacity; the other is to make an additional support device outside the gearbox to support the reel, which is very difficult for processing and assembly. Craftsmanship br...

Problems solved by technology

Usually, in order to meet the requirements of lifting speed and low-speed bearing capacity requirements, the reduction box needs to choose a large speed ratio, which undoubtedly increases the manufacturing cost of the lifting mechanism.
