Abstract
The invention relates to a supporting element for a rolling bearing. The supporting element comprises an annular inner cover matched with an axis, an annular outer cover matched with a shaft neck, and a bearing chamber arranged between the outer edges of the annular inner cover and the annular outer cover, and used for fastening the inner cover and the outer cover, and an accommodating chamber for accommodating the bearing is formed among the inner cover, the outer cover and the bearing chamber; a plurality of damping rings are arranged on the contact surface of the bearing chamber and the bearing. According to the supporting element disclosed by the invention, the bearing accommodating chamber is formed by the inner cover, the outer cover and the bearing chamber, and moreover, the elastic damping rings are arranged on the radial contact surface of the bearing, the radial play of the bearing is reduced, and the running noise of a steel ball during the rotation of the bearing is lowered by virtue of the deformation of the elastic material of the damping rings.
Description
Technical field
The present invention relates to bearing support and bearing, bearing support and bearing that especially can vibration and noise reducing.
Background technique
Rolling bearing, because frictional loss is few, is used widely in machinery.But axle is because some reasons such as speed are brought vibration, and rolling bearing can not effectively be decayed to vibration because of its structure.
Summary of the invention
The first object of the present invention is to provide a kind of bearing support, and the second object is to provide a kind of bearing of energy vibration and noise reducing.
The first object of the present invention completes by following technical solution, a kind of bearing support, and it comprises: annular inner cap, it coordinates with axle center; Shaped outer cover, it coordinates with axle journal; And bearing chamber, it is arranged between annular inner cap, shaped outer cover outer rim and fastening inner cap, enclosing cover, forms the accommodating chamber that holds bearing between described inner cap, enclosing cover and bearing chamber; Described bearing chamber and bearing surface of contact are provided with some damping rings.
The second object of the present invention completes by following technical solution, and the bearing of vibration and noise reducing, comprises bearing body, it is characterized in that: it also comprises a supporting member, and this supporting member comprises annular inner cap, and it coordinates with axle center; Shaped outer cover, it coordinates with axle journal; And bearing chamber, it is arranged between annular inner cap, shaped outer cover outer rim and fastening inner cap, enclosing cover, forms the accommodating chamber coordinating with bearing play between described inner cap, enclosing cover and bearing chamber; Described bearing chamber and bearing surface of contact are provided with some damping rings.
The present invention forms a bearing accommodating chamber by inner cap enclosing cover and bearing chamber, and with the radially surface of contact of bearing, elastic damping ring is set, and utilizes the deformation of damping ring elastic material, reduces bearing play radially, the running noises of steel ball while reducing bearing rotary.Utilize the elastic damping of damping ring simultaneously, absorb the vibration of bearing roller impact outer ring, stop outer ring conduct vibrations to bearing chamber and motor, thereby reduce the vibration of motor.The quantity of damping ring also can specifically be determined according to the motor rotational speed under particular case, rolling element quantity and bear vibration frequency analysis.
Brief description of the drawings
Fig. 1 is generalized section of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is done to detailed introduction:
As shown in Figure 1: a kind of bearing support, an axle 4 of assembling in the middle of this supporting member, supporting member comprises: annular inner cap 1, it coordinates with axle center; Shaped outer cover 2, it coordinates with axle journal; And bearing chamber 3, it is arranged between annular inner cap, shaped outer cover outer rim, forms the accommodating chamber that holds bearing 5 between inner cap, enclosing cover and bearing chamber.In addition, inner cap, enclosing cover and bearing chamber are strained in aggregates by clamping bolt 6 in the axial direction.Bearing chamber and bearing radially surface of contact are provided with two damping rings 7, and damping ring is that rubber material is made.Meanwhile, inner cap, enclosing cover and axle surface of contact are taked labyrinth seal 8 structures.
The bearing of vibration and noise reducing, comprises rolling bearing 5 bodies, and bearing body supporting member, and this supporting member comprises annular inner cap, and it coordinates with axle center; Shaped outer cover, it coordinates with axle journal; And bearing chamber, it is arranged between annular inner cap, shaped outer cover outer rim, between inner cap, enclosing cover and bearing, pass through radially seam location, and inner cap, enclosing cover and bearing chamber are fastening by clamping bolt 6 in the axial direction, between inner cap, enclosing cover and bearing chamber, form like this accommodating chamber coordinating with bearing play.Bearing chamber and bearing surface of contact are provided with two damping rings, and damping ring is rubber material.Bearing chamber and accommodating chamber are full of lubricant grease.Because inner cap, enclosing cover and axle surface of contact are taked labyrinth seal 8 structures, can effectively keep the sealing effect of lubricant grease in supporting member.When lubricant grease is bearing assemble, add bearing and bearing chamber memory space, motor continuous operation, after 1 year, suitably supplements grease.
