Abstract
Provided is a combination bearing for a rapid press, which belongs to the field of spare and accessory parts of a press. A conventional ball bearing is easy to be damaged and get stuck. The combination bearing for a rapid press comprises a ball bearing and a 7-shaped copper bearing. An outer ring of the ball bearing is fixedly connected to an axle seat, and an inner ring is fixedly connected to a crankshaft. One side of the ball bearing is spaced by abutting against an end face of the axle seat, and the other side covers the axle seat through a gland. The copper bearing is arranged between the axle seat and the crankshaft. The crankshaft is provided with a boss. The head part of the 7-shaped copper bearing is spaced back and forth by the boss and the end face of the axle seat. The copper bearing is provided with a groove, adjacent to a crankshaft surface, forming an oil trench. The combination bearing for a rapid press is advantageous in that a combination bearing is adopted, and the rigidity and operation precision of a machine tool are improved; heat productivity of a support portion is reduced; damage and locking of bearing during running can be effectively prevented.
Description
Technical field
The utility model belongs to forcing press spare and accessory parts field, and is especially relevant with combination bearing with a kind of fast pressure machine.
Background technology
The fast pressure machine that uses on the metal forming machinery at present all is to adopt ball bearing with bearing; When forcing press is worked; Ball bearing receives the opposition when impacting steel plate, and this opposition is very big in the momentary action power of contact steel plate, so ball bearing often damages; But also bearing is stuck in use easily, causes the accident.
Summary of the invention
The purpose of the utility model will overcome existing ball bearing exactly and exist fragilely, and stuck shortcoming easily provides a kind of stable, and the combination bearing that is not easy to damage, and for this reason, the utility model adopts following technical scheme.
Fast pressure machine is used combination bearing, comprises ball bearing, and the outer ring of ball bearing is fixedly connected with axle bed; Inner ring is fixedly connected with bent axle; One side of ball bearing is spacing against the end face of axle bed, and opposite side is loaded in the axle bed through the gland lid, and it is characterized in that: described combination bearing also comprises " 7 " font copper bearing; This copper bearing is arranged between axle bed and the bent axle; Bent axle is provided with boss, and is spacing before and after the end face of " 7 " font copper bearing head by this boss and axle bed, and the copper bearing is provided with groove near the bent axle face and forms oil duct; When this combination bearing is stressed, ball bearing idle running, the rotation of copper shaft strength; When not stressing, the ball bearing running.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Described axle bed is provided with fuel feed hole and oil outlet, and fuel feed hole is crisscross and connect with the oil duct that is arranged on the copper bearing, and lubricating oil is imported from fuel feed hole; Oil outlet output is through the oil duct of copper axle bed, to copper bearing effectively lubricating; Reduce wear, reduce caloric value.
The inner ring both sides of described ball bearing are provided with the gap, are used to add lubricating oil.
Described gland is through being bolted on the axle bed.
The contact-making surface of described gland and axle bed is provided with O shape ring, prevents that lubricating oil from overflowing.
Described gland and bent axle contact-making surface are provided with seal, prevent that lubricating oil from overflowing.
The utility model can reach following beneficial effect: the utility model adopts combination bearing, has improved the rigidity and the running precision of lathe, has reduced the caloric value of support zone, damages locking in the time of effectively preventing the bearing operation.
