In above-mentioned dust-proof deep groove ball bearing, the both ends of the surface up and down of described dust cover also all have the annular gear edge of protrusion, described annular gear is along being resisted against on the inwall of bearing outer ring.By the design on annular gear edge, between annular gear edge and the inwall of bearing outer ring, forming surface face seals further, and further increase the sealing between dust cover and bearing outer ring, dust-proof effect is better, extends the working life of bearing.
In above-mentioned dust-proof deep groove ball bearing, between described annular gear edge and the inwall of bearing outer ring, be equipped with seal ring.Further increase sealing between dust cover and bearing outer ring by arranging seal ring, dust-proof effect is better, extends the working life of bearing.
In above-mentioned dust-proof deep groove ball bearing, described annular dop adopts elastic material to make, and described dop drive fit is connected in annular slot.Annular dop adopts elastic material to make, self have certain can deformation quantity, more for convenience, and dop is by self elastic strain and annular slot drive fit in clamping, can and the cell wall of annular slot between formed and seal.
In above-mentioned dust-proof deep groove ball bearing, the circular groove two that described annular slot comprises circular groove one and is opened on circular groove one sidewall, described circular groove one is cone tank and groove width reduces gradually along opening toward bottom direction, and shape and the described annular slot of described annular dop match.Circular groove one designs for cone tank, has certain leading role, snaps in more for convenience, and have certain pretightening force between cone tank and annular dop, sealing effect is better simultaneously.
In above-mentioned dust-proof deep groove ball bearing, described dust cover is also provided with some radiating fin.By the design of radiating fin, have good heat sinking function, make bearing can be in good working environment, working life is higher.
In above-mentioned dust-proof deep groove ball bearing, described dust cover adopts heat sink material to make.Dust cover adopts heat sink material to make, and have good heat sinking function, make bearing can be in good working environment, working life is higher.
Compared with prior art, this dust-proof deep groove ball bearing has the following advantages: 1, have multi-sealed between the outer ring of dust cover and bearing outer ring, can effectively prevent the impurity etc. in air from entering Bearing inner by the gap between dust cover and bearing outer ring, in the annular mounting groove that the inner ring edge of dust cover is embedded in bearing inner race and Spielpassung, can not impact the operation of bearing, and forming station terrace between dust cover inner ring edge and the sidewall of annular mounting groove, extend the path that the impurity in air enters, can effectively prevent the impurity etc. in air from entering Bearing inner by the gap between dust cover and bearing inner race, dust-proof is effective, extend the working life of bearing.2, be demountable structure between dust cover and bearing outer ring, be convenient to repair and replacement.3, the design of radiating fin, has good heat sinking function, and make bearing can be in good working environment, working life is higher.
