Abstract
The utility model relates to an anti-reverse device with a detachable bearing sleeve, which comprises a bearing base, an anti-reverse end cover, a bearing, an anti-reverse disk, round nuts, a frame oil seal, a rotating shaft, a column pin, a bearing sleeve, a felt oil seal, adjusting nuts and screws. The utility model is characterized in that at least more than two thread through holes distributed symmetrically are arranged on the co-working surface of the bearing sleeve and the bearing. Detaching screws are arranged in the thread through holes; and three or four through holes distributed symmetrically are arranged on the co-working surface of the bearing sleeve and the bearing. The utility model has the advantages that when in detaching, the detaching screws can be screwed into the thread through holes to form the bottom of the bearing sleeve, and the detaching screws form a jack together with the bearing sleeve, so that the bearing can be pulled out by the detaching screws, thereby avoiding the damage to the bearing. Moreover, due to detachment to the utility model becomes more convenient.
Description
Technical field
The utility model relates to a kind of vertical sewage pump anti-reverse mechanism, particularly a kind of anti-reverse mechanism with detachable type bearing housing.
Background technique
Vertical sewage pump is easy to form counter-rotating when starting, so the counter-rotating will prevent starting mode of pump with anti-reverse mechanism the time.Bearing housing is a component part of anti-reverse mechanism, bearing is contained on the bearing housing, bearing housing is connected by key with axle, rotate with axle, owing to must adopt interference fit between bearing and the bearing housing, so when equipment need carry out demolition and maintenance or change, for bearing is pulled down from bearing housing, generally knock bearing so that both are separated, be easy to like this damage of bearings is caused certain loss.
Summary of the invention
The purpose of this utility model is to solve bearing on the anti-reverse mechanism and the difficult problem of the existing dismounting of bearing housing interference fit in the prior art, and a kind of anti-reverse mechanism with detachable type bearing housing is provided.A kind of anti-reverse mechanism of the utility model design with detachable type bearing housing, comprise bearing support, anti-reverse end cap, bearing, counnter attack rotating disk, round nut, outside framework oil seal, rotating shaft, straight pin, bearing housing, felt collar oil sealing, adjust nut, screw, it is characterized in that: the tapped through hole that is symmetrically distributed more than at least two is arranged on the fitting surface of bearing housing and bearing, the dismounting nut is arranged in tapped through hole.The tapped through hole that is symmetrically distributed on the fitting surface of bearing housing and bearing has three or four.The utility model advantage is when dismounting as long as the dismounting nut is screwed into tapped through hole below bearing housing, dismounting nut and bearing housing form one " jack " by screw-thread fit, by the dismounting nut bearing is ejected, so just avoided the damage of bearing, and convenient disassembly.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is an existing bearing nested structure schematic representation.
Embodiment
Comprise bearing support 10, anti-reverse end cap 3, bearing 9, counnter attack rotating disk 4, round nut 7, outside framework oil seal 11, rotating shaft 12, straight pin 5, bearing housing 8, felt collar oil sealing 6 among the figure, adjust nut 1, screw 2, it is characterized in that: the tapped through hole 14 that is symmetrically distributed more than at least two is arranged on the fitting surface of bearing housing 8 and bearing 9, dismounting nut 13 is arranged in tapped through hole 14.The tapped through hole 14 that is symmetrically distributed on the fitting surface of bearing housing 8 and bearing 9 can have three or four and more than.
When needing dismounting, to dismantle nut 13 and be screwed into tapped through hole 14 from bearing housing 8 belows, the tapped through hole 14 of dismantling nut 13 and bearing housing 8 this moment forms one " jack " by screw-thread fit, bearing 9 can be ejected by turning dismounting nut 13, so just avoided the damage of bearing 9, and convenient disassembly.
When normal the use, can be screwed in the tapped through hole 14, play the effect of sealing, prevent that the lubricating grease in the bearing support 10 from leaking with short screw.
Claims (2)
1. anti-reverse mechanism with detachable type bearing housing, comprise bearing support, anti-reverse end cap, bearing, counnter attack rotating disk, round nut, outside framework oil seal, rotating shaft, straight pin, bearing housing, felt collar oil sealing, adjust nut, screw, it is characterized in that: the tapped through hole that is symmetrically distributed more than at least two is arranged on the fitting surface of bearing housing and bearing, the dismounting nut is arranged in tapped through hole.
