Abstract
The utility model discloses cam combination bearings, including main shaft, several capacity eccentric bearings are axially arranged with along main shaft on the main shaft, fixing piece is equipped between the inner ring and main shaft of the capacity eccentric bearing, the circumferential side wall of the capacity eccentric bearing is equipped with connector, and the utility model provides a kind of cam combination bearing for reducing operating friction power.
Description
Technical field
The utility model relates to field of bearings, are more particularly to cam combination bearing.
Background technique
It is general using being arranged continuous several cams on main shaft in existing continuous booster body, each cam with
One link mechanism connection drives the cam rotation on main shaft, actuated by cams connecting rod makees piston motion, right by main axis
The object being increased is pressurized, but this mechanism needs the regular coating lubricating oil on cam, reduces the abrasion of cam, leads
It is more greasy in cause cabinet, it not enough cleans, simultaneously because cam and connecting rod belong to sliding friction, calorific value is big, and noise is big.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of cam combination bearing for reducing operating friction power.
To achieve the above object, the utility model provides following technical solution: cam combination bearing, including main shaft, institute
Several capacity eccentric bearings that are axially arranged on main shaft along main shaft are stated, fixing piece is equipped between the inner ring and main shaft of the capacity eccentric bearing,
The circumferential side wall of the capacity eccentric bearing is equipped with connector.
The two sides of the further capacity eccentric bearing are equipped with sealing ring.
The further fixing piece is bolt, and the inner ring that the bolt passes through capacity eccentric bearing contradicts on main shaft.
The further bolt is at least provided with two.
The further fixing piece is the fixture block being located on capacity eccentric bearing inner ring, and the main shaft is equipped with to be cooperated fastly with card
Card slot.
Cooperate in conclusion the utility model is rolled by the inner ring and outer ring that make capacity eccentric bearing, reduces frictional force, subtract
Lack calorific value, reduces noise, while keeping away the seal oil in capacity eccentric bearing by the sealing ring of capacity eccentric bearing two sides
Exempt to refuel in cabinet, has realized non-oil ultra high vacuum system, reduce environmental pollution.

Fig. 2 is the structural schematic diagram of the utility model cam combination bearing；
Fig. 3 is the explosive view of the utility model cam combination bearing.
Mark explanation: 1, main shaft；2, capacity eccentric bearing；3, connector；21, inner ring；22, outer ring；23, sealing ring；3, it connects
Part.
Specific embodiment
It is described further referring to figs. 1 to embodiment of the Fig. 3 to the utility model cam combination bearing.
Cam combination bearing, including main shaft 1, it is described along several capacity eccentric bearings 2 that are axially arranged with of main shaft 1 on the main shaft 1
Fixing piece is equipped between the inner ring 21 and main shaft 1 of capacity eccentric bearing 2, the circumferential side wall of the capacity eccentric bearing 2 is equipped with connector 33,
The two sides of the capacity eccentric bearing 2 are equipped with sealing ring 23.
Connector 33 and connecting rod in the present embodiment are rotation connections, it is ensured that equipment can work normally, and connector 33 can
To be to punch to connect with link rotatable on link block, when main shaft 1 rotates, due to the inner ring 21 and main shaft 1 of capacity eccentric bearing 2
It is to be fixed by fixing piece, and inner ring 21 is eccentric setting, so that the connector 33 on the outer ring 22 of capacity eccentric bearing 2 be made to put
It is dynamic, and since the inner ring of capacity eccentric bearing 2 21 and outer ring 22 are to roll cooperation, reduce frictional force, reduce calorific value, reduces
Noise, while by the sealing ring 23 of capacity eccentric bearing 2 two sides by the seal oil in capacity eccentric bearing 2, exempted from cabinet plus
Oil realizes non-oil ultra high vacuum system, reduces environmental pollution.
Embodiment 1: the fixing piece is bolt, and the inner ring 21 that the bolt passes through capacity eccentric bearing 2 contradicts on main shaft 1,
Main shaft 1 is resisted by bolt, so that inner ring 21 be made to hold main shaft 1 tightly.
Preferably for the bolt at least provided with two, two fixations are more firm for the present embodiment.
Embodiment 2: the fixing piece is the fixture block being located on 2 inner ring 21 of capacity eccentric bearing, and the main shaft 1 is equipped with fast with card
The card slot of cooperation keeps the inner ring 21 of capacity eccentric bearing 2 and main shaft 1 fixed by fixture block and card slot cooperation.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
