Steel wire rope reduction gearbox

Abstract

The invention discloses a steel wire rope reduction gearbox. The reduction gearbox comprises a reduction gearbox body, a first main shaft is arranged on the reduction gearbox body, a winch mechanism for stranding steel wire ropes is arranged at the output end of the first main shaft, a back-twist driving device and a main input load are arranged on the two sides of the bottom of the reduction gearbox body respectively, a transmission mechanism II is arranged between the main input load and the first main shaft and is in transmission connection with the main input load and the first main shaft, and a transmission mechanism I is arranged between the back-twist driving device and the reduction gearbox body and is in transmission connection with the back-twist driving device and the reduction gearbox body. According to the reduction gearbox, during use, when 100% non-back-twist in the steel wire rope synthesis process or 100% back-twist in the steel wire rope synthesis process is realized, the main input load serves as a power source, rotation of a winch in the winch mechanism is realized, and meanwhile, back-twist of different percentages in the steel wire rope reduction gearbox synthesis process can be realized through the back-twist driving device.

Description

technical field [0001] The invention belongs to the technical field of steel wire rope synthesis machines, in particular to a steel wire rope speed reducer. Background technique [0002] In the process of producing cables or steel wire ropes, one of the processes is to wind multiple copper wires or steel wires together. This process is called stranding. The operating equipment for this process is a cage stranding machine, and the driving equipment for the cage stranding machine is Gearbox. At present, in the cable manufacturing and steel wire rope manufacturing industries, 100% untwisting of the cable is required when twisting steel wires, strands and other cables; 100% of the cable is required when twisting cables such as flat wires, fan-shaped wires, and special-shaped wires. % No back twisting; 100% ± 30% back twisting is required when twisting some special strands, special-shaped wires and other cables. [0003] The main reduction box of the cage-type twisting machine ...

AI Technical Summary

Problems solved by technology

[0003] The main reduction box of the cage-type twisting machine in the prior art can realize the untwisted state of the cable is basically a 100% untwisted mode, but cannot realize the untwisted mode of 100% ± 30% of the cable, or other percentage untwisted modes. Leading to the substandard quality of steel wire rope synthesis
