How to transform the bearing are fat capping machine - bearing knowledge

Bearing all fat capping machine is a dedicated railway wagon bearing seal cover component assembly equipment. For a long time, often appear in the process of work, bearing seal cover component partial pressure, the phenomenon such as dislocation, scrap lead to components, raw materials costs increase, affect production, and even the whole bearing the quality of the products are affected. In addition, after the bearings are fat, and cannot be reset to the feeding center position, unable to realize automatic blanking, so you need to straighten the staff manual after blanking, due to large bearing quality, objectively increase the labor intensity of the workers, and affected the production efficiency. Design for bearing in the assembly process of technical problems, seriously analysis, discusses the fat capping machine were optimized. ( 1) Change gland cylinder body structure and the supporting surface, increase the bearing strength and rigidity of the system, make sure the system under the frequent pressure shock, to maintain a good centering precision. ( 2) From double motor drive are fat instead of single motor drive were fat, make the whole machine structure is compact, reduces the axial size, reduce the area, greatly reduce the energy consumption at the same time. ( 3) Adjust the action cylinder stroke, ensure that bearing gland are fat are reset after cylinder pushing the feeding position, automatic blanking. ( 4) In mechanism design, increase the elasticity, gland, before both sides fat friction plate under the action of spring force, first of all, bearing a reservation ( Friction plate with spline guidance, centering accurate) So as to ensure the bearing will not occur in the process of moving shadow, also can avoid feeding the gland deviation caused by inaccurate problem. Working principle as shown in the appended drawings, into left and right sides of the gland seal cover components within 4 and 6. When feeding roller bearing inner components to the location as seen here. Gland cylinder piston 2 under the effect of pressure oil to the right, both fat lining 5 first contact with the left end bearing inner components, push the bearing inner component moves to the right. Then, the component within the right contact to the friction plate on the right side. Then, the spring is compressed and at a certain pressure internal components to achieve target; Again to the right, gland, when collision block 3 down journey switch K2 signal, said gland. On either side of the motor drive pulley 1, through the spline shaft transmission torque, under the influence of friction drive bearing inner ring spinning, implementation are fat. Fat time ( 0 ~ 3分钟) Adjustable, all fat spindle speed 150 r/min. After all fat, gland cylinder piston 2 back, when collision block signaling when down the switch K1, reset the cylinder piston 7 under pressure oil is moving to the left, bearing in reset after a gland cylinder under the action of being pushed back to the initial position; Reset the cylinder piston returned, K3 release travel switch signal, the workpiece under the expected, into the next cycle. Conclusion the improved design are fat capping machine, in the realization of gland are fat, and other functions, on the action principle of more scientific and more reasonable, solved the partial pressure in the process of gland, dislocation problems, ensure the quality of the gland and up-down material, at the same time, greatly reduce the energy consumption, improve the production efficiency.
