Description

Ball bearing capable of dissipating heat and ventilating

Technical Field

The utility model relates to a bearing field especially relates to a ball bearing that can dispel heat and ventilate.

Background

Ball bearing is a mechanical part very commonly used, generally all can install the shield between ball bearing's outer lane and inner circle, and the shield basically seals the space between bearing inner circle and the bearing outer lane, but to some service environment that need ventilation cooling, just can't produce the radiating effect, so need a bearing structure that can dispel the heat and ventilate.

SUMMERY OF THE UTILITY MODEL

The utility model provides a but ball bearing of ventilation dispels heat, simple structure opens has the heat dissipation ventilation hole, can realize the heat dissipation ventilation effect.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a ball bearing that can dispel heat and ventilate, includes bearing inner race and bearing inner race, bearing inner race and bearing inner race between be provided with the steel ball, bearing inner race and bearing inner race in all be provided with the louvre that a plurality of link up both ends around the circumference, bearing inner race and bearing inner race between both ends all install the shield.

Preferably, the heat dissipation holes are obliquely arranged.

Preferably, the shape of the heat dissipation holes is arc-shaped strip.

Preferably, the dustproof cover comprises a framework ring and a flexible cover body wrapped on the outer side of the framework ring, clamping grooves are formed in two ends of the circumferential inner side wall of the bearing outer ring, and the radial outer edge of the flexible cover body is embedded into the clamping grooves.

Preferably, a circle of flange is arranged at two ends of the circumferential outer side wall of the bearing inner ring, and the radial inner side edge of the flexible cover body is embedded into a groove in the inner side wall of the flange.

Compared with the prior art, the beneficial effects of the utility model are that:

simple structure opens has the heat dissipation ventilation hole, can realize the heat dissipation ventilation effect, and the shield adopts rigid structure and flexible construction to combine together moreover, simple to operate, and is sealed effectual, longe-lived.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-4, the utility model provides a but ball bearing of heat dissipation and ventilation, including bearing inner race 1 and bearing inner race 2, bearing inner race 1 and bearing inner race 2 between be provided with steel ball 3, bearing inner race 1 and bearing inner race 2 in all be provided with the louvre 5 that a plurality of link up both ends round the circumference, bearing inner race 1 and bearing inner race 2 between both ends all install shield 4.

In the using process of the bearing, the bearing inner ring 2 can rotate, the heat dissipation holes 5 can ventilate when the bearing inner ring rotates, and the heat dissipation holes 5 on the bearing outer ring 1 can ventilate.

As an embodiment of the utility model, louvre 5 be the slant and arrange, 5 shapes of louvre be arc strip, this kind of structure is favorable to the spiral of air current to pass through when bearing inner race 2 rotates.

As an embodiment of the dust cap 4, the dust cap 4 includes a skeleton ring 7 and a flexible cap body 8 wrapped outside the skeleton ring 7, two ends of a circumferential inner side wall of the bearing outer ring 1 are provided with clamping grooves 6, and a radial outer edge of the flexible cap body 8 is embedded into the clamping grooves 6.

Simultaneously, the both ends of the circumference lateral wall of bearing inner race 2 be provided with round flange 9, the radial inboard edge of flexible lid 8 be provided with the recess of embedding flange 9 inside wall in, flange 9 can be spacing flange 9, prevent that shield 4 from deviating from.

While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features of the disclosed embodiments of the present invention can be used in any combination with each other, and the description of such combinations is not exhaustive in the present specification only for the sake of brevity and resource conservation. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
