Baffle, what which was fixed on inner ring both ends waves surface.The crescent moon bearing eliminates guarantor using the scheme for completely filling roller
Hold frame.
Component is waved according to the first hydraulic pump of offer, including the swinging seat that matches and is waved, swinging seat and is waved
Between the connection of above-described the first crescent moon bearing, the crescent moon bearing outer ring fixes with swinging seat, and inner ring, which is fixed on, to wave
Surface completely fills roller in the raceway formed between outer ring and inner ring；The surface of waving at inner ring both ends is fixed for limiting roller
Baffle.
Another aspect according to the present utility model waves the crescent moon bearing of component, packet for second provided by the utility model
Include the arc-like outer band with rib, raceway and roller, the outer ring directly forms raceway with the surface of waving for waving component, in raceway
Completely fill roller；It further include the baffle for being limited to all rollers, what which was fixed on roller both ends waves surface.It should
Crescent moon bearing eliminates retainer, without bearing inner race using the scheme for completely filling roller.
Second of hydraulic pump provided by the utility model waves component, including the swinging seat that matches and waves, feature
Be: swinging seat and being connected using above-described second of crescent moon bearing between waving, the crescent moon bearing outer ring with wave
Seat is fixed, and outer ring and the surface of waving for waving component directly form raceway, completely fills roller in raceway；Wave surface in roller both ends
It is fixed for limiting the baffle of roller.
Another aspect according to the present utility model provides a kind of hydraulic pump, including the first or second of hydraulic pump shake above
Put component.
Between above-described two kinds of crescent moon bearings and crescent moon bearing with wave component, hydraulic pump belong to one it is total
Utility model design, that is, eliminate the retainer in crescent moon bearing arrangement, avoid and wave caused by being easily damaged because of retainer
Failure.The crescent moon bearing can use in a corrosive environment, effectively extend bearing and wave the service life of component.Manufacture letter
It is single, it is easy for installation, production efficiency is substantially increased, production cost is reduced.Roller is limited with baffle, also there is light-weight, load
The advantages of lotus is big, prevents bearing locking.It is waved and swinging seat in conjunction with original, installs crescent moon bearing described in the utility model additional,
In the case where no oil pressure can be reached, equipment is still worked normally, and maintains the repertoire for waving component.
