Description

Bearing of speed reducer of gearbox

Technical Field

The utility model relates to a bearing equipment technical field specifically is a gearbox speed reducer bearing.

Background

The reducer is a power transmission mechanism that reduces the number of revolutions of a power source to a desired number of revolutions by using a speed converter of a gear and obtains a large torque, and a bearing of the reducer plays a role of supporting a gear shaft or a link between revolutions therein. Speed reducer gear bearing is after long-time use, and the dead phenomenon of card can appear in inner circle and outer lane, and the frictional force between pivot and the inner circle is too big promptly for bearing and pivot are difficult to dismantle, consequently under this condition, even after dismantling by force, impaired condition all can appear in bearing or pivot, and current bearing inner circle does not have the heat radiation structure, uses insecurely.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a gearbox speed reducer 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 gearbox speed reducer bearing, including outer lane and inner circle, the inner circle both sides are installed in the outer lane through the pivot, the centre of outer lane and inner circle is equipped with the raceway, align to grid has a plurality of rollers in the raceway, the fixed holder that is equipped with on a plurality of rollers, the holder includes the circle frame, evenly be equipped with a plurality of spacers on the circle frame, a plurality of spacers and raceway looks gomphosis, a plurality of spacers are established in a plurality of roller both sides, evenly be equipped with a plurality of louvres on outer lane and the inner circle, outer lane and interior cladding elastic buffer spare, the last cladding of elastic buffer spare has the wearing layer, the inner circle inside wall is equipped with the oil filler point, the oil.

Preferably, the bottom parts of the outer ring and the inner ring are provided with dust covers.

Preferably, the elastic buffer is made of rubber.

Preferably, the wear-resistant layer is made of wear-resistant steel.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model has simple structure and convenient operation, and the bearing has certain elastic expansion amount through the arranged elastic buffer part; the ball is prevented from being protruded from the side edge in rotation by the arranged retainer, and the running smoothness of the ball at the inner side is effectively improved; through the arranged heat dissipation holes, the heat of the bearing can be reduced, and the service life is prolonged; the wear-resisting property of the bearing is improved through the arranged wear-resisting layer, and the service life is prolonged.
