Abstract

A wedge elastic coupler mainly comprises a semi coupler, an elastic component, a shield, and the like, wherein the semi coupler is a tooth inserting structure having the same end face, a wedge elastic component is arranged between the teeth, and the shields are separately fixed on the semi coupler through bolts. When the utility model works, the teeth of the semi coupler on a prime motor push the wedge elastic component, and the wedge elastic component pushes the teeth of the semi coupler on a driven machine, thereby achieving the purpose of the delivery motion of the two shafts. The product can be made into serial product with various torque ranges. The utility model is applicable for mine machinery, chemical industry machinery, small hydroelectricity apparatus, generating apparatus, cement apparatus and the like, especially for not only the mechanical drive of the bidirectional operating and the one-way operating which are frequently started, but also the mechanical drive of the low-speed operating and high-speed operating.

Description

The wedge block type elastic coupling flexible coupling

(1) technical field

The utility model belongs to mechanical engineering field, relates to a kind of wedge block type elastic coupling flexible coupling.

(2) background technique

Employed coupling in China's existing mechanical equipment can be divided into rigid coupling and elastic coupling flexible coupling etc. substantially.So-called elastic coupling flexible coupling is exactly a kind of coupling of two transmission shafts transmitting movement by means of the distortion of middle elastic members.The elastic coupling flexible coupling close with the utility model has: rubbercushioned sleeve bearing coupling, elastic dowel pin shaft coupling, spring column pin gear coupling, quincunx elastic coupling flexible coupling, nylon rod pin elastic coupling flexible coupling etc.Above-mentioned these coupling all exist various problems: or complex structure, processing difficulties; Or transmission power is little, and using scope is subjected to certain restriction; Or elastic component is short stressed unreasonable working life; Or elastic component is changed difficulty; Or shortcoming such as reliability is low.

(3) summary of the invention

It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, the wedge block type elastic coupling flexible coupling of reliability height, long service life.

The utility model can be achieved through the following technical solutions above-mentioned purpose, the wedge block type elastic coupling flexible coupling mainly comprises half-coupling, elastic component, two half-couplings are the identical tooth-like structure of end face, the tooth of half-coupling and tooth are staggered to be inserted, the wedge block type elastic component is housed between tooth and the tooth, and two guard shields are fixed by bolts to respectively on two half-couplings.

The utility model can produce following good effect:

1, elastic component only bears nip load in the utility model structure, and is stressed reasonable, long service life.

2, overall structure is in light weight, compares its weight saving 25% with nylon rod pin elastic coupling flexible coupling.

3, simple in structure, the part kind is few, is easy to processing, and processing cost is low.

4, the replacing that centering, elastic component are installed is all than being easier to, and is easy to use.

5, reliability height, but still safe handling under the situation that elastic component lost efficacy, noise is little, running is steady.

6, can make the series product of various torque ranges, produce in batches, enlarge economic benefit.

(4) description of drawings

Fig. 1 is the utility model wedge block type elastic coupling flexible coupling master pseudosection.

Fig. 2 is the top plan view of the utility model wedge block type elastic coupling flexible coupling.

(5) embodiment

As shown in Figure 1 and Figure 2, the utility model is mainly by half-

coupling

1,3, wedge block type elastic component 2, guard shield 4 is formed, earlier half-

coupling

1,3 is contained on the axle of prime mover and driven machine respectively, install behind the centering between the tooth and tooth of half-

coupling

1,3 that wedge block type elastic component 2 packed into, guard shield 4 is fixed on the half-

coupling

1,3 with bolt 5 respectively.

During work, the tooth of half-coupling promotes wedge block type elastic component 2 on prime mover, and wedge block type elastic component 2 promotes the tooth of half-coupling on the driven machine, thereby reaches the purpose of diaxon transmitting movement.

The utility model is applicable to mining machinery, chemical machinery, small-size hydroelectric equipment, power generating equipment, cement equipment etc.This product is particularly useful for the bidirectional movement of frequent starting, also is applicable to the mechanical transmission of unidirectional running; Both be applicable to low-speed running, also be applicable to the mechanical transmission that runs up.
