Abstract
The utility model discloses a five-tooth prolate shaft for a chain block, which comprises a shaft body, wherein the left end of the shaft body is provided with a thread section, the annular outer wall of the right end of the shaft body is provided with wheel teeth, the annular outer wall of the middle part of the shaft body is provided with an annular groove, and a nylon layer is coated on the outer wall of the wheel teeth. The five-tooth prolate shaft has a simple structure, is convenient to assemble, is suitable for the chain block, and satisfies the application requirement of the chain block on special components.
Description
Technical field:
The utility model relates generally to the parts of using in the chain block, relates in particular to a kind of five tooth major axis that are used for chain block.
Background technology:
Chain block is to rotate by dropping manual chain, bangle wheel, friction lining ratchet, drg seat is pressed into one rotates jointly, and the tooth major axis is rotatable lamella gear, tooth minor axis and splined hole gear just.Like this, the chain hoist wheel of device on the splined hole gear just drives hoisting chain, thereby promotes weight reposefully.Adopt ratchet friction disk type one-way drg, can automatic brake under load, ratchet under the effect of spring with ratchet engaged, drg trouble free service.It has that safe and reliable, easy maintenance, mechanical efficiency height, bangle pulling force are little, deadweight lighter in carry, less, the long-lived characteristics of good looking appearance size, be applicable to that factory, mine, building ground, harbour, dock, warehouse etc. are as install machinery, lifting cargo, especially for open-air and non-transformer operation, more demonstrate preceence.But because the chain block inner components is more, mounting structure more complicated each other need be used the parts of some special constructions.In the prior art, the five tooth major axis that chain block is used have the inconvenient defective of assembling, need improve its structure.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of five tooth major axis that are used for chain block to be provided, and it is simple in structure, and is easy to assembly, is applicable to chain block.
The utility model is achieved through the following technical solutions:
A kind of five tooth major axis that are used for chain block, it is characterized in that: include axis body, the axis body left end is provided with thread segment, and the annular outer wall of axis body right-hand member is provided with the gear teeth, the annular outer wall of the middle part of axis body is provided with annular groove, is coated with nylon layer on the outer wall of the described gear teeth.
Described a kind of five tooth major axis that are used for chain block, it is characterized in that: the described gear teeth include five.
Splined hole gear matched in the utility model and the chain block is used, and satisfies the user demand of chain block.
Described nylon layer has strengthened the resistance to abrasion of the gear teeth.
The utility model has the advantages that:
The utility model is simple in structure, is convenient to assembling, is applicable to chain block, has satisfied the user demand of chain block for special parts.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to accompanying drawing.
A kind of five tooth major axis that are used for chain block, include axis body 1, axis body 1 left end is provided with thread segment 2, and the annular outer wall of axis body 1 right-hand member is provided with five gear teeth 3, the annular outer wall of the middle part of axis body 1 is provided with annular groove 4, is coated with nylon layer 5 on the outer wall of the described gear teeth 3.
Claims (2)
1. five tooth major axis that are used for chain block, it is characterized in that: include axis body, the axis body left end is provided with thread segment, and the annular outer wall of axis body right-hand member is provided with the gear teeth, the annular outer wall of the middle part of axis body is provided with annular groove, is coated with nylon layer on the outer wall of the described gear teeth.
2. a kind of five tooth major axis that are used for chain block according to claim 1, it is characterized in that: the described gear teeth include five.
