Description

Double-oscillating-bar bearing

Technical Field

The utility model relates to a bearing technical field specifically is a double pendulum rod bearing.

Background

The main function of the bearing is to support the mechanical rotator, reduce the friction coefficient in the movement process and ensure the rotation precision. The swing rod bearing is one kind of bearing, is used to support mechanical rotator and reduce its friction coefficient in motion, and features small friction resistance, low power consumption, high mechanical efficiency and easy start, supporting rotating shaft and parts on the shaft, and maintaining the normal working position and rotation precision of the shaft.

However, when the existing swing rod bearing is used on an electric hammer, the impact force cannot be increased, the service life is short, and the requirement on special equipment cannot be met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a double pendulum rod bearing to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a double-pendulum rod bearing, includes pendulum rod one, pendulum rod two, bearing inner race, bearing body, ball, cardan shaft and bearing core, the center department of bearing body is provided with the bearing core, and the bearing core outside cover has the cardan shaft, two around the cardan shaft is provided with on the bearing core, and two the cardan shaft diameter is different, the cardan shaft outside all overlaps there is the bearing inner race, and installs the ball between cardan shaft and the bearing inner race, the bearing inner race is provided with two, and the bearing inner race is connected with pendulum rod one and pendulum rod two respectively, pendulum rod one sets up in two the place ahead of pendulum rod.

Preferably, the horizontal distance between the first swing rod and the second swing rod is smaller than the diameter of the outer ring of the bearing, and the horizontal distance between the first swing rod and the second swing rod is larger than the diameter of the bearing core.

Preferably, the two diameters of the cardan shaft are different, and the front diameter of the cardan shaft is larger than the rear diameter of the cardan shaft.

Compared with the prior art, the beneficial effects of the utility model are that: the double-swing-rod bearing is provided with the two swing rods, a certain horizontal distance is reserved between the first swing rod and the second swing rod, the impact force of the electric hammer can be increased, the service life is prolonged, and the structure of the double swing rods also meets the requirements of some special equipment.
