Abstract
The invention discloses a rubber-cushioned sleeve bearing coupling fast to replace. The rubber-cushioned sleeve bearing coupling fast to replace comprises a right half coupling body, a pin, an elastic sleeve and a nut. A pin hole for the pin to penetrate is formed in the right half coupling body. A sliding sleeve is arranged between the pin and the pin hole. The outer diameter of the sliding sleeve is not smaller than that of the elastic sleeve. A pressure plate fixedly connected with the right half coupling body is arranged on a right side cover of the sliding sleeve. The right end of the pin stretches out of the pressure plate and is then connected with the nut in a threaded mode. The outer diameter of the sliding sleeve is slightly larger than that of the elastic sleeve. When the nut and a bolt are loosened, the pressure plate, the sliding sleeve, the pin and the elastic sleeve are disassembled from the right edge of the coupling together, the elastic sleeve can be conveniently replaced, coaxiality correction is not needed again after replacement, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of rubbercushioned sleeve bearing coupling, be specifically related to a kind of quick changing type rubbercushioned sleeve bearing coupling.
Background technique
Shown in Fig. 1, Fig. 2 is rubbercushioned sleeve bearing coupling more common in dynamic power machine transmission, pin is connected with the flange of left and right half-coupling, one end of pin forms secure fit with the cylindricality on cylndrical surface or conical surface and nut and right half-coupling flange or taper pin-hole, is contained in the column pin hole on left half-coupling flange with the other end of elastic sleeve.The outside of elastic sleeve is provided with dovetail groove, to increase elastic deformation amount, and because the external diameter of elastic sleeve is slightly less than pin-and-hole diameter, thus can small electromotor axle and the relative displacement of water pump spindle.Elastic sleeve is made with rubber, and its hardness is Shao Shi A70 ± 5, tensile strength > 15MP.The feature of rubbercushioned sleeve bearing coupling is: simple in structure, easy for installation, size is little, lightweight, there is certain elasticity and shock-absorbing capacity, can small electromotor axle and water pump spindle between certain relative shift, be mainly used in middle low power drive line.As used in the transmission of driven by motor water pump, left half-coupling is installed on motor shaft, and right half-coupling is installed on water pump spindle.Because elastic sleeve is easily damaged parts, while changing elastic sleeve, only need unclamp nut, pin is pulled down from the left side, change elastic sleeve, change easily.
But, if rubbercushioned sleeve bearing coupling uses at diesel engine and drives in the transmission of water pump, left half-coupling is the flywheel of diesel engine, right half-coupling is arranged on water pump spindle, in the time that elastic sleeve is damaged, the space that does not allow pin to pull down due to the flywheel left side, the construction bolt of diesel engine or water pump and base must be pulled down, disengagement flywheel or water pump spindle are connected with coupling, then change elastic sleeve, mounting diesel engine again after replacing completes, radiator, water pump, water pipe etc., again proofread and correct coaxality, this Renewal process is too loaded down with trivial details, length expends time in, bring very large trouble to user.
Summary of the invention
The object of the invention is to provide a kind of quick changing type rubbercushioned sleeve bearing coupling, and it is simple, convenient that elastic sleeve is changed, and enhances productivity.
For achieving the above object, the technical solution used in the present invention is: a kind of quick changing type rubbercushioned sleeve bearing coupling, comprise right half-coupling, pin, elastic sleeve and nut, described right half-coupling is provided with the pin-and-hole wearing for described pin, between described pin and pin-and-hole, be provided with sliding sleeve, the external diameter of described sliding sleeve is not less than the external diameter of described elastic sleeve, and the right cap of described sliding sleeve is provided with the pressing plate being connected with described right half-coupling, and the right-hand member of described pin is spirally connected with described nut after stretching out described pressing plate.
Above-mentioned quick changing type rubbercushioned sleeve bearing coupling also comprises left half-coupling, and this left half-coupling is provided with and holds the left end of described pin and the column pin hole of described elastic sleeve, and the internal diameter of the internal diameter of described pin-and-hole, the external diameter of sliding sleeve and column pin hole equates.
In technique scheme, described pressing plate is kidney-shaped plate, and its two ends are fixedly connected with described right half-coupling by bolt respectively.
Preferably, above-mentioned quick changing type rubbercushioned sleeve bearing coupling comprises 12 described pins and 12 described elastic sleeve.
In technique scheme, the left side of described nut is provided with compression spring, improves coupling mechanism force.
Preferably, the flywheel that described left half-coupling is diesel engine.
In technique scheme, the outside of described elastic sleeve is provided with a plurality of trapezoidal grooves vertically.
Because technique scheme is used, the advantage that the present invention compared with prior art has is:
1. in the present invention, the external diameter of sliding sleeve is slightly larger than the external diameter of elastic sleeve, unclamp nuts and bolt, pressing plate, sliding sleeve, pin and elastic sleeve can be pulled down from the right of coupling together, are convenient to the replacing of elastic sleeve, after replacing, do not need again to proofread and correct coaxality, enhance productivity.
