Abstract

The utility model provides an elastic pin tooth type coupler which comprises an upper semi-coupler main body and a lower semi-coupler main body, wherein the lower peripheries and the upper peripheries of the upper semi-coupler main body and the lower semi-coupler main body are provided with a plurality of first elastic pins and a plurality of second elastic pins in an encircling way; the first elastic pins and the second elastic pins are externally sleeved with a plurality of outer covers; and the middle parts of the upper semi-coupler main body and the lower semi-coupler main body are sleeved with a plurality of first fixed rings and a plurality of second fixed rings. As the internal threads of the first fixed rings and the second fixed rings are mutually matched with the outer threads of the upper semi-coupler main body and the lower semi-coupler main body, the elastic pin tooth type coupler has the advantages that the outer covers and the elastic pins can not be shifted up and down, the disassembly and the assembly of an input shaft and an output shaft are convenient, the maintaining and the replacing of the parts of the whole set of equipment are very simple, the semi-coupler main bodies are directly withdrawn from or inserted into the enclosure of the outer sleeves and the elastic pins, the overhauling efficiency is greatly improved on the premise that the transmission power of the coupler is not changed, and the first fixed rings and the second fixed rings are hard to become flexible during working since a plurality of first screw nuts, a plurality of second screw nuts, a plurality of first plum blossom-shaped spacers and a plurality of second plum blossom-shaped spacers are additionally arranged on the first fixed rings and the second fixed rings.

Description

A kind of spring column pin gear coupling

Technical field

The utility model belongs to the assembling field of machinery, particularly a kind of spring column pin gear coupling under the vertical user mode of narrow space for maintenance.

Background technique

In the prior art, ZL type spring column pin gear coupling (GB/T5015-1985) is the standardized coupling of versatility that often uses on a kind of machinery.This coupling when dismounting, need be at coupling radially keep enough space for maintenances.Outer baffle ring on the ZL type spring column pin gear coupling is two and passes through bolt annular element on the coat, and its effect is the axial float when overcoming overcoat and spring column pin work.When taking coupling apart, at first need the fixing bolt of baffle ring is pulled down, take out spring column pin, remove overcoat, just can disassemble relevant parts.On the special equipment of some structures, swirl gear as the material distributing machine in circular homogenizing stockyard commonly used, cement plant, owing to there are not enough space for maintenances, can't use general spanner to pull down the fixedly bolt of baffle ring, the part of coupling, input and output shaft and associated have to be moved axially to simultaneously the position that has living space and just can take apart.Like this, make equipment inspection and renewal part bother very much, working efficiency is low.

The model utility content

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of under the vertical user mode of narrow space for maintenance, equipment inspection and renewal part are easy, the spring column pin gear coupling of high working efficiency.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of spring column pin gear coupling, comprise half-coupling body, following half-coupling body, and described going up between half-coupling body, the following half-coupling body keeps a gap; The described lower periphery that goes up the half-coupling body is around being provided with several first spring column pins, and described half-coupling upper part of body periphery down is around several second spring column pins are set; Described first spring column pin, second spring column pin) the sheathed overcoat in the outside, the upper end of middle part, described first spring column pin and the overcoat of half-coupling body on described, sheathed one first retaining ring, the bottom of described retaining ring has one first annular skirt, and the described first annular skirt cover is located at the top of described first spring column pin and overcoat; In the described lower end of middle part, described second spring column pin and the overcoat of half-coupling body down, sheathed one second retaining ring, the top of described second retaining ring has one second annular skirt, and the described second annular skirt cover is located at the bottom of described second spring column pin and overcoat;

Preferably, described first retaining ring is provided with internal thread, and is corresponding, and the corresponding site of half-coupling body is provided with outside thread on described, and the outside thread of the internal thread of described first retaining ring and last half-coupling body mates mutually; Described second retaining ring is provided with internal thread, and is corresponding, is provided with outside thread at the described corresponding site of half-coupling body down, and the internal thread of described second retaining ring mates mutually with the outside thread of following half-coupling body;

Preferably, half-coupling body top, sheathed one first nut in first retaining ring upper end on described; At described half-coupling body top, sheathed one second nut in the second retaining ring lower end down;

Preferably, sheathed one first pad between described first retaining ring and first nut; Sheathed one second pad between described second retaining ring and second nut;

Preferably, described first pad, second pad are blossom type.

Compared with prior art, advantage of the present utility model is, because the internal thread of first and second retaining ring and the outside thread of upper and lower half-coupling body mate installation mutually, the play up and down that has stoped overcoat and spring column pin, made things convenient for the dismounting of input, output shaft, make that maintenance, the replacing component of complete equipment are very simple, realized that the half-coupling body directly extracts or insert from the encirclement of overcoat and spring column pin, under the prerequisite that does not change the coupling transmitted power, improved overhaul efficiency greatly; Set up first and second nut and first and second blossom type pad on first and second retaining ring top, it is loosening to make that first and second retaining ring is difficult in the course of the work.
