Abstract
The utility model discloses a kind of rig rotor rear bearing shock-damping structure, belong to auxiliary equipment of rig field, comprise rotor rear bearing and casing bearing chamber, rubber sleeve is increased between rotor rear bearing and casing bearing chamber, rubber sleeve is enclosed within rotor rear bearing, rotor rear bearing and rubber sleeve are drive fit, and rubber sleeve and casing bearing chamber are also drive fit.The utility model overcomes prior art defect, rubber sleeve forms " being flexible coupling " between rotor rear bearing and casing bearing chamber, plays the effect of damping, effectively reduces the noise in rig working procedure, reduce the rig wearing and tearing of rotor rear bearing, extend the working life of rotor.
Description
Technical field
The utility model relates to auxiliary equipment of rig field, especially a kind of bearing shock-damping structure.
Background technique
The structure of current rig rotor rear bearing position is: the rotor being equipped with bearing directly installs in casing bearing chamber, without other auxiliary components.The shortcoming of this structure is: ratio of the first, vibrating is higher: rotor high-speed operates the vibrations caused, directly pass to bearing, because bearing and bearing chamber are for being rigidly connected, casing and handle are directly passed in vibrations, the vibrations produced cause people to operate numb hand, bring uncomfortable feeling.The second, in order to shake control within the acceptable range, require higher to rotor dynamic balancing; 3rd., bearing with bearing chamber for be directly connected, after rig service time is long, bearing chamber can loosen, and causes bearing outer ring to have rotation, causes the heat that rubbed, and causes the damage of bearing.
Model utility content
The utility model technical issues that need to address are to provide a kind of rig shock-damping structure, and this structure effectively can reduce the vibrations of rig rotor rear bearing in bearing chamber, reduce noise, reduce bearing wear, extend bearing working life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
Rig rotor rear bearing shock-damping structure, comprise rotor rear bearing and casing bearing chamber, between rotor rear bearing and casing bearing chamber, increase rubber sleeve, rubber sleeve is enclosed within rotor rear bearing, rotor rear bearing and rubber sleeve are drive fit, and rubber sleeve and casing bearing chamber are also drive fit; The inside of described rubber sleeve is provided with Steel Skeleton; The outer surface of described rubber sleeve is set to spline structure.
Owing to have employed technique scheme, the technological progress that the utility model obtains is:
The utility model overcomes prior art defect, rubber sleeve forms " being flexible coupling " between rotor rear bearing and casing bearing chamber, plays the effect of damping, effectively reduces the noise in rig working procedure, reduce the rig wearing and tearing of rotor rear bearing, extend the working life of rotor.
Rubber sleeve internal surface in the utility model and the outer surface of rotor rear bearing are drive fit, the outer surface of rubber sleeve and the internal surface of bearing chamber are drive fit, without relative movement between them, so just ensure the status requirement of rig rotor, ensure that rig rotor rear bearing outer ring, rubber sleeve and casing bearing chamber keep relative static conditions simultaneously, avoid because wearing and tearing appear in relative movement.
Rubber sleeve in the utility model is elastic fastener, when rig rotor rear bearing machining accuracy slightly error, also successfully can assemble use with bearing chamber, thus improve the up-to-standard rate of efficiency of assembling and finished product.The outer surface of rubber sleeve is set to spline structure, and can ensure can not affect assembling because of tension friction tight with bearing chamber while; The Steel Skeleton that the inside of rubber sleeve is arranged can avoid rubber sleeve distortion in assembly process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, rotor rear bearing, 2, rubber sleeve, 3, casing bearing chamber, 4, rotor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
Rig rotor rear bearing shock-damping structure, as shown in Figure 1, comprise rotor rear bearing 1, rubber sleeve 2 and casing bearing chamber 3, its rotor rear bearing 1 is connected to rotor 4 rear portion, rubber sleeve 2 is enclosed within rotor rear bearing 1, and then rotor rear bearing 1 is loaded in casing bearing chamber 3, rubber sleeve 2 forms " being flexible coupling " between rotor rear bearing 1 and casing bearing chamber 3, and the internal surface of rubber sleeve 2 is close to the outer surface of rotor rear bearing 1, the outer surface of rubber sleeve 2 and casing bearing chamber 3 are also drive fits, without relative movement between them, so just ensure the status requirement of rig rotor, ensure rig rotor rear bearing 1 simultaneously, rubber sleeve 2 and casing bearing chamber 3 keep relative static conditions, avoid because wearing and tearing appear in relative movement.The inside of described rubber sleeve 2 is provided with Steel Skeleton, can avoid rubber sleeve gross distortion impact assembling in assembly process; The outer surface of rubber sleeve 2 is set to spline structure, and can ensure can not affect assembling because of tension friction tight with bearing chamber 3 while.This " being flexible coupling " structure between rotor rear bearing 1 and casing bearing chamber 3, plays the effect of damping, effectively reduces the noise in rig working procedure, reduces the rig wearing and tearing of rotor rear bearing, extends the working life of rotor.
