CN203412972U - Large-torque coupler of conveying equipment - Google Patents

Abstract

The utility model discloses a large-torque coupler of conveying equipment. The coupler comprises a first semi-coupler and a second semi-coupler which are connected with each other, wherein a coupler inner shell is arranged outside the first semi-coupler; a coupler outer shell is arranged outside the second semi-coupler; the coupler inner shell is embedded into the coupler outer shell; matched surfaces of the coupler inner shell and the coupler outer shell are connected with each other through a pin. The large-torque coupler can effectively guarantee a requirement on the coaxial precision of two transmission shafts, so that mounting and debugging are implemented without stopping; the damage fault of a nylon pin caused by unbalance of load fluctuation is greatly alleviated; the running rate of the equipment is improved, and the working period and the cost for maintenance are reduced.

Description

A kind of conveying equipment big torque clutch

Technical field

The utility model relates to a kind of coupling, specifically big torque clutch.

Background technique

Existing coupling is the pin that utilizes some nonmetallic material to make, and is placed in the two involutory holes of half-coupling, realizes two half-couplings connect by nylon pin transmitting torque:

(1) be not suitable for the transmission device of load imbalance;

(2) oscillation damping power power is poor, and noise is larger.

Above two kinds of situations easily cause nylon pin to damage, and affect equipment operation.

Existing coupling is only applicable to medium and relatively high power transmission, unbalanced and vibration damping be there are certain requirements with noise and need to strictly be controlled for the fluctuation of load; Nylon pin has trace compensation two axial lines excursion capability, during elastic component work, is sheared, and functional reliability extreme difference, is only applicable to require very low middling speed drive line, is not suitable for the operating mode that functional reliability is had relatively high expectations; Nylon pin damages frequent, and operation rate is low; It is high that equipment is protected during-operation service expense cost.

Model utility content

The purpose of this utility model is the deficiency existing for prior art, provides that a kind of precision is high, good stability and reduce the conveying equipment big torque clutch of maintenance cost.

For realizing above-mentioned model utility object, the technical solution adopted in the utility model is a kind of conveying equipment big torque clutch, comprise interconnective the first half-coupling and the second half-coupling, described the first half-coupling outside is provided with coupling inner casing, the second half-coupling outside is provided with coupler casing, coupling inner casing embeds in coupler casing, and fitting surface connects by pin.

Described coupling inner casing and coupler casing are provided with equally distributed suitable column pin hole, for pin is installed.

Described pin is nylon pin.

The utility model changes coupler structure design: the assembling form of two half-couplings is changed into the structure that shell coordinates with inner casing, be uniformly distributed column pin hole nylon pin is installed at fitting surface, realize two half-couplings connect by nylon pin transmitting torque.

Beneficial effect: the utility model can effectively guarantee the requirement of two transmission shaft coaxial accuracies, Installation and Debugging are accomplished without any letup; Reduced greatly the nylon pin damage fault causing because the fluctuation of load is unbalanced; Improve operation rate, reduced the man-hour and the expense that because of maintenance, drop into.
