By adopting technique scheme, described dust cover and bearing inner race and outer ring socket, can prevent that dust impurity from entering bearing inside, fix dust cover and bearing by clip, annular ring inner side on described clip is provided with groove, described bearing outer ring is provided with projection, described groove and projection socket, facilitate groove and projection location, described dust cover diameter is larger than bearing outer diameter, annular ring is stepped, annular ring upper end and dust cover size are suitable, annular ring lower end and bearing outer ring size are suitable, form the device of a closing seam, described clip is fixed and sealing pivot and dust cover by securing means, can effectively prevent that dust impurity from entering rotating shaft inside, thereby prevent the inner laying dust of rotating shaft, lubricant oil is not contaminated, bearing can run well, do not affect using effect, increase the working life of bearing.
The utility model is further set to: described securing means is the fixing frame of the through hole that is fixedly connected with annular ring, and described through-hole wall is provided with screw thread, and described fixing frame is bolted.
By adopting technique scheme, described bolt is established threaded through hole with inwall and is fixedly connected with, and fixes annular ring, thereby firmly fixed rotating shaft and dust cover can effectively prevent that dust impurity from entering bearing inside.
The utility model is further set to: in described dust cover, be provided with groove, in described groove, be provided with seal ring.
By adopting technique scheme, described dust cover cover rim is provided with groove, seal ring in described groove and outer ring and inner ring join, seal ring high resilience and rebound elasticity, suitable mechanical strength, stable performance, in medium, be difficult for swellingly, thermal pinch is little, effectively prevents that dust from entering bearing inside, prevent bearing internal lubrication oil pollution, extend bearing working life.
The utility model is further set to: described clip is made up of stainless steel material.
By adopting technique scheme, stainless steel has stronger resistant to rust ability, and the clip of stainless steel is difficult for corrosion, and stability is strong, guarantees that bearing and dust cover are firmly fixing, prevents that impurity from entering bearing inside.
The utility model is further set to: on described clip, scribble protective paint.
By adopting technique scheme, protective paint is a kind of coating of protecting metal surface to avoid chemistry or electrochemical corrosion, has good thermostability, forms fine and close paint film to stop the intrusion of corrosive material, non-combustible, environmentally safe.
