Abstract
Disclosed is a cross shaft assembly provided with a spring at the head face, relating to the technical field of shaft couplings used in mining and metallurgical industries. The cross shaft comprises a cross shaft(1), an inner sleeve(2), a rolling body(3), an outer sleeve(4), a bolt(5), an end closure(6), a head face raceway(7), a head face bearing(8), a spring(9) and a forkhead(10); wherein the inner sleeve(2) is inlaid on the neck journal of the cross shaft(1), and the inner sleeve(2) and the neck journal of the cross shaft(1)are threaded in the outer sleeve(4) fixed on the axle hole of the forkhead(10); the rolling body(3) is arranged between the inner sleeve and the outer sleeve; the head face bearing(8) is located at the top part of the inner sleeve(2), and then the end closure(6) is fixed at the axle hole of the forkhead(10)through the bolt(5); and the spring(9) is arranged between the matching parts of the head face raceway(7) and the end closure(6). The utility model improves the reliability of the shaft coupling, remarkably prolongs the service life of the cross shaft assembly and effectively improves the production efficiency.
Description
Technical field
The utility model relates to the coupling technical field of mine, metallurgy industry; Especially relate to the cross assembly that a kind of end face is provided with wavy spring or belleville spring.
Background technique
The cross assembly of traditional universal coupling with spider normally adopts between end cap and the jaw and directly installs the end face bearing additional between bolton, cross axle and the end cap and cooperate, and the maximum drawback of this structure is to be difficult to guarantee the axially locating of cross axle.Because the specific applying working condition of rolling machinery, coupling is in thump usually, working state is discontinuous and the work down of the torque limit state of high load, under the effect of this impact and high pulling torque, cross axle play in cross assembly produces impact force.This impact force can make end face raceway generation contact impression cause the coupling revolution malfunctioning on the one hand; The more important thing is when it acts on the end cap of coupling, bolt of cover fast fatiguing under the effect of impulsive load lost efficacy, and then in use the serious accident that end cap is washed out can occur, and it is out of service to cause working group to be forced to, reduce working efficiency, increased cost of production.
The coupling that is used for transmission of power in view of the rolling machinery of present metallurgy industry is mainly based on universal coupling with spider, and universal coupling with spider has not reached the requirement of basic industry fast development at aspects such as working life, safety coefficient, economic benefits; So the technological improvement for universal coupling with spider has become the focus that receives much concern in the industry.
Summary of the invention
In order to overcome the deficiency in the background technique, the utility model discloses the cross assembly that a kind of end face is provided with spring, be subjected to axial impact to produce the contact impression the malfunctioning and end cap of its revolution to be washed out and the problem that makes global failure to solve the coupling end-face raceway.Improve the reliability of coupling, rised appreciably the working life of cross assembly, improved manufacturing efficiency effectively.
In order to realize goal of the invention of the present utility model, the utility model adopts following technological scheme;
A kind of end face is provided with the cross assembly of spring, comprises cross axle, interior cover, rolling element (3), overcoat, bolt, end cap, end face raceway, end face bearing, spring and jaw; Cover is embedded on the axle journal of cross axle wherein, interior cover is threaded onto in the overcoat that is fixed on the jaw axis hole with the axle journal of cross axle, install rolling element additional between the interior overcoat, the end face bearing is positioned at the cover top, by bolt end cap is fixed on the axis hole position of jaw again, is provided with spring between the matching part of described end face raceway and end cap.
Described end face is provided with the cross assembly of spring, and described spring is multilayer ripple coil spring, to top ripple spring flush end spring, to top ripple spring closed end spring, interface ripple coil spring, breach ripple coil spring, internal tooth belleville spring or external tooth belleville spring.
Owing to adopted said structure, the utlity model has following beneficial effect;
The cross assembly structure that end face described in the utility model is provided with spring makes and is subjected to the constant force effect all the time between each matching part of cross assembly top and keeps impaction state, has eliminated the axial float of cross axle effectively; Simultaneously, fixedly the bolt between end cap and the jaw also is subjected to the effect of constant force all the time, has increased the fatigue resistance of itself, has prevented the premature failure of bolt, has effectively prolonged the working life of cross assembly.The utlity model has advantages such as simple and reasonable, safe and reliable, solved the problem that the coupling end-face raceway is easily washed out by axial impact generation contact impression and end cap, reached raising coupling life cycle, increase the purpose of transmission efficiency.
