Description
Technical Field
The utility model belongs to the technical field of bearings, and relates to a deep groove ball bearing, in particular to a novel deep groove ball bearing.
Background
At present, two sides of a bearing on the market are matched with dust covers, and the dust covers are mainly used for preventing external impurities from entering the bearing to wear accessories; but the leakproofness between present bearing shield and the bearing body is not good enough, and the sealing washer does not carry out effectual location, leads to the bearing during operation, and the sealing washer is off normal easily, influences the leakproofness.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provides a novel deep groove ball bearing with stable sealing performance and high efficiency.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a novel deep groove ball bearing, includes outer lane and inner circle, outer lane and inner circle between be equipped with the shield, its characterized in that, shield and outer lane and inner circle between have and be equipped with sealing device, the shield on have the seal groove that supplies this sealing device to install, outer lane and inner circle on all have outside axial arch and cooperate with sealing device and be used for the holding ring to sealing device location, sealing device include the sealing washer body that the inner has the breach, the holding ring cooperate in the breach of sealing washer body, will through the breach sealing washer body inner be formed with two rings of seal sections, seal section inner wall department all evagination have with holding ring seal complex seal lip.
In the novel deep groove ball bearing, the sealing ring is U-shaped.
In the novel deep groove ball bearing, the dust cover is in clearance fit with the outer ring and the inner ring.
Compared with the prior art, the novel deep groove ball bearing has the advantage of high sealing performance.
