Abstract

The utility model provides a belt conveyor with long service life, comprising a motor, a reducer and a transmission drum, wherein the reducer and a transmission drum shaft are connected through a serpentine spring coupling, the serpentine spring coupling comprises two half-couplings, a tooth groove is arranged on a shaft sleeve of each half-coupling and is internally provided with a serpentine spring used for connecting the two half-couplings, and a horizontal split encloser is arranged at the outer side of the connecting part of the two shaft sleeves. Because the adopted serpentine spring coupling has small volume and light weight, the belt conveyor is particularly suitable for the condition of large torque; and with the adoption of the belt conveyor, under the condition of transferring an equal torque, a moment of the reducer and the drum, adhesive tape and the like is reduced, and the service life of a main part of the belt conveyor is prolonged.

Description

The belt conveyer of a kind of long life

Technical field

The utility model relates to a kind of belt conveyer, is specially a kind of belt conveyer of long service life.

Background technology

The basic structure of existing coupler is to be made up of through attaching parts the basic half the same shaft coupling of two structures.In mechanical drive, generally, select dissimilar coupler for use according to the particular case of transferring power.The elastic dowel pin shaft couplings that adopt connect imput shaft and driven shaft more on the existing belt conveyer, make it to rotate jointly with transfer torque, and under the high pulling torque situation, the moment of flexure of reductor and drum shaft is bigger, has influenced the service life of bearing.

Summary of the invention

The purpose of the utility model provides the belt conveyer of a kind of long life.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:

The belt conveyer of a kind of long life; Comprise electrical motor; Connect through Falk flexible coupling between retarder and the driving drum, described retarder and driving roller shaft, described Falk flexible coupling comprises two and half shaft couplings; Have teeth groove on the axle sleeve of half shaft coupling, the serpentine spring that connects two and half shaft couplings is housed in the teeth groove.

Compare with the existing belt conveyer of spring column pin formula drive coupling that adopts, the utility model adopt the Falk flexible coupling volume little, in light weight, be specially adapted to the situation of high pulling torque.Under the situation of transmitting equal moment of torsion, reduced the moment of flexure of reductor and cylinder, adhesive tape etc., prolonged the service life of major parts such as belt conveying machine bearing.

Description of drawings

Fig. 1 is the structural representation of the utility model belt conveyer.

Fig. 2 is the Falk flexible coupling of the utility model.

Among the figure, 1-electrical motor, 2-retarder, 3-driving drum, 4-Falk flexible coupling, 5-half shaft coupling, 6-axle sleeve, 7-spring, 8-case.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be specified.

The belt conveyer of described a kind of long life of the utility model; Comprise electrical motor 1; Connect through Falk flexible coupling 4 between the retarder 2 and driving drum 3,3 of described retarder 2 and driving drums, described Falk flexible coupling 4 comprises two and half shaft couplings 5; Have teeth groove on the axle sleeve 6 of half shaft coupling 5, the serpentine spring 7 that connects two and half shaft couplings 5 is housed in the teeth groove.Spring 7 can adopt the high strength alloy steel material preparation.

Spring 7 can freely swing in the teeth groove on the axle sleeve 6, make between its half shaft coupling 5 that can allow to be connected to have the deviation that radially, axially reaches angle, this coupler to hold the deviation ability big, thereby the centering of coupler is required low than other coupler.When coupler received the impact of load and changes, spring 7 can deform, and it and contact of tooth flanks face also change, thereby can absorb impact energy, reached to reduce vibrations and absorb the effect of impacting, and its damping effect can reach more than 30%.

The outside, junction of two axle sleeves 6 is provided with horizonally split formula case 8, and the installation of spring 7 and replacing need not to move axle sleeve 6.

Claims (2)

1. the belt conveyer of a long life; Comprise electrical motor (1); Retarder (2) and driving drum (3) is characterized in that: connect through Falk flexible coupling (4) between described retarder (2) and driving drum (3) axle, described Falk flexible coupling (4) comprises two and half shaft couplings (5); Have teeth groove on the axle sleeve (6) of half shaft coupling (5), the serpentine spring (7) that connects two and half shaft couplings (5) is housed in the teeth groove.

2. the belt conveyer of a kind of long life according to claim 1 is characterized in that: be provided with horizonally split formula case (8) outside the junction of two axle sleeves (6).
