Abstract
The utility model relates to mechanical conveying equipment, in particular to a novel hand-operated winch. The novel hand-operated winch comprises a base, a winding drum, a transmission gear group, a ratchet wheel and ratchet pawl component and a handle, wherein the winding drum is fixed into the base through a fixing pin, a transmission shaft is arranged on one side of the handle, a fixed rod and a round hole which is used for being matched with the transmission are formed on one side of the base, a ratchet pawl is fixed onto the fixed rod, a ratchet wheel is arranged on the transmission shaft, the end part of the transmission shaft penetrates the round hole and extends into the base, and the ratchet wheel on the transmission shaft and the ratchet pawl on the fixed rod are matched with each other. By the adoption of the unique design of the ratchet pawl, the ratchet wheel can be meshed with the ratchet pawl normally without adding an elastic torsion spring outside the ratchet pawl, so that the risks caused by the invalidation of the torsion spring are avoided, and the brake stability is better guaranteed; and a rolling bearing is mounted at a shaft head of a transmission component, so that the transmission efficiency of the winch is high.
Description
Technical field
The utility model relates to a kind of mechanical transmission equipment, especially a kind of novel manual winch.
Background technology
Along with the continuous development of science and technology, the application of various large-scale, heavy devices or spare and accessory parts more and more widely, and it is because volume is big, Heavy Weight, the transmission under some occasion need transmit by the labour-saving mechanical transmission equipment; Hand winch is as existing commonplace mechanical transmission, it is mainly used in traction or promotes, by the rope traction on the reel, reach the instrument of traction or lifting weight or equipment, the driving efficiency of the stability of brake equipment and transmission parts is very important, and ratchet in the existing hand winch brake equipment and ratchet engagement exist certain hidden danger, mainly be torsion and the ratchet engaged of existing ratchet by torsion spring, the size of torsion spring heat treatment and torsion is determining the stability of deceleration and stopping performance, in case torsion spring lost efficacy, that consequence is just hardly imaginable; Also having the spindle nose of existing hand winch transmission parts is to be connected with containing bearing with the hole, and such driving efficiency is lower, service life short.
Summary of the invention
The utility model is in order to solve defective and the deficiency that above-mentioned prior art exists, and provides a kind of deceleration and stopping performance novel manual winch stable, driving efficiency height, long service life.
The technical solution of the utility model: a kind of novel manual winch, comprise pedestal, reel, driving gear set, click assembly and handle, described reel is fixed in the pedestal by set pin, described handle one side is provided with transmission shaft, described pedestal one side is provided with fixed link and is used to cooperate the circular hole of transmission shaft, described ratchet is fixed on the fixed link, described ratchet is arranged on the transmission shaft, the end of described transmission shaft is passed circular hole and is put in the pedestal, and ratchet on the described transmission shaft and the ratchet on the fixed link cooperatively interact.
Preferably, described transmission shaft is socketed with antifriction-bearing box outward.
Preferably, described gear cluster comprises big gear wheel and miniature gears, and described big gear wheel is arranged on reel one side, and described miniature gears is arranged on the end of transmission shaft, the circular hole that the end of described transmission shaft is passed on the pedestal puts in the pedestal, and the big gear wheel of the miniature gears of end and reel one side is meshing with each other.
Preferably, described reel middle part and pedestal both sides are respectively equipped with through hole, and described set pin passes the through hole of pedestal and reel and fixes.
The utility model adopts unique detent design, need not the torsion spring that ratchet adds elastic force, and ratchet and pawl can both guarantee normal engagement, has avoided because the risk that the inefficacy of torsion spring brings has guaranteed the stable of braking better; Simultaneously antifriction-bearing box is installed, is made the driving efficiency height of winch at the spindle nose of transmission parts.
