Abstract

The utility model discloses a laminated pin type elastic coupler and relates to elastic couplers. The laminated pin type elastic coupler solves the problem that an existing elastic pin coupler can not be used in occasions under high temperatures. The laminated pin type elastic coupler comprises a half coupler I, a half coupler II, and pins used for connecting the half coupler I with the half coupler II, wherein an even number of pins are evenly distributed on the circumference of the coupler. Each pin is a laminated type pin made of spring steel, wherein the laminated type pin is composed of a profile-modified cylinder and a drum-shaped body, symmetrical planes are machined on the two sides of the profile-modified cylinder respectively, and the drum body is split into at least two parallel layers in the axial direction. The laminated pin type elastic coupler has the advantages of being good in buffering performance, strong in bearing capacity, small in number of maintenance times, long is service life, and capable of being used in the occasions under high temperatures.

Description

A kind of stacked pin elastic coupling flexible coupling

Technical field

The utility model relates to elastic coupling flexible coupling, particularly a kind of stacked pin elastic coupling flexible coupling.

Background technique

Elastic dowel pin shaft coupling is a kind of coupling commonly used, and it uses the pin transmitting torque.Because nylon material is easily processed, and shock-absorbing capacity is good, and the pin of coupling is made of nylon usually.But the nylon non-refractory can produce permanent deformation under the condition of high temperature, and coupling was lost efficacy.

As shown in Figure 1, it is subject to the restriction of pin material to the elastic dowel pin shaft coupling structure of prior art, usually can only under normal temperature environment, use.This coupling is used on the equipment in near-thermal source, can affect shock-absorbing capacity, and the higher workplace in temperature, can not be used this coupling.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the shortcoming of prior art, and a kind of stacked pin elastic coupling flexible coupling is provided, the problem that the occasion that the existing elastic dowel pin shaft coupling of solution can not be higher in temperature is used.

Technical solutions of the utility model are for achieving the above object:

A kind of stacked pin elastic coupling flexible coupling, comprise; I half-coupling, II half-coupling, and the pin that connects I half-coupling and II half-coupling, it is uniform that described pin is even number on the circumference of coupling, it is characterized in that: described pin is a kind of stacked pin of manufacturing with spring steel, the profile of described stacked pin consists of two sections of correction of the flank shape cylindrical body and drum shaped body, described correction of the flank shape cylindrical body is to process symmetry plane in the cylindrical body both sides, and described drum shaped body at least cuts into two parallel synusia vertically.

Described I half-coupling and II half-coupling arrange respectively two kinds of different shaped jet holes, to adapt to, place correction of the flank shape cylindrical body and drum shaped body, two kinds of alternate configurations of hole shape, and adjacent hole shape oppositely arranges.

The root that two described parallel synusia are cut face is circle hole shape; The length of described parallel synusia is less than the length of drum shaped body.

The utility model compared with the prior art, because the pin that rigidity is larger cuts into a plurality of synusia in the cydariform section, the cross section of each layer reduces, according to theory of mechanics of materials, the module of anti-bending section in each cross section diminishes, each layer of flexible, good springiness, therefore, stacked pin has shock-absorbing capacity stably when coupling is worked.Because the stressed of stacked each layer of pin is gradual change, increase gradually, therefore, stacked pin transmitting torque is functional.The utlity model has shock-absorbing capacity good, bearing capacity is strong, the few maintenance, and the advantage that the life-span is long can be used for the occasion that temperature is higher simultaneously.

Embodiment

As shown in Fig. 2,3,4,5,6, a kind of stacked pin elastic coupling flexible coupling, comprise; I half-coupling 1, II half-coupling 2, and the pin 3 that connects I half-coupling and II half-coupling, it is uniform that described pin 3 is even number on the circumference of coupling; Described pin 3 is a kind of stacked pins of manufacturing with spring steel, the profile of described stacked pin consists of 32 two sections of correction of the flank shape cylindrical body 31 and drum shaped body, described correction of the flank shape cylindrical body 31 is to process symmetry plane A in the cylindrical body both sides, avoid pin to rotate, guarantee that stacked pin is subject to force direction constant; Described drum shaped body 32 provides level and smooth angular displacement compensation performance for transmission, and described drum shaped body 32 at least cuts into two parallel synusia 321 vertically, and the parallel synusia 321 of the present embodiment is divided into 6 layers.Cross section when not cutting layer is compared, and the cross section of each synusia reduces, and module of anti-bending section diminishes, and each layer flexible, and stacked pin shows good elasticity, has shock-absorbing capacity stably when coupling is worked.If stacked pin is subject to force direction (with F, to mean power) as shown in Figure 4, so, during stacked pin work, the stressed of each layer from top to bottom is followed successively by: 1 layer, 2 layers, 3 layers, 4 layers, 5 layers, 6 layers, when power F hour, before only having, which floor can be stressed, when power F is larger, that sells is stressed by the 1st layer of beginning, successively pass to the 2nd layer, the 3rd layer ... until the 6th layer, the stressed of each layer of pin is gradual change, increase gradually, therefore the utlity model has good transmitting torque performance.The stacked pin of coupling uniform some on certain circumference, the more transmitting torques of stacked pin quantity are larger; Stacked pin should be adjacent on a coupling be oppositely put into, therefore the setting of stacked pin even number (the present embodiment is 8, sees Fig. 3) preferably.

Two kinds of different shaped jet holes are set respectively on described I half-coupling 1 and II half-coupling 2, to adapt to, place correction of the flank shape

cylindrical body

31 and 32, two kinds of alternate configurations of hole shape of drum shaped body, adjacent hole shape oppositely arranges.

The root of minute tangent plane that two described parallel synusia are 321 is circle hole shape; The length of described parallel synusia 321 is less than the length of drum shaped body.

The thickness of described stacked pin synusia 321 and the number of plies, determine according to concrete stressing conditions and the service condition of coupling.
