Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution:
A kind of oil drilling machine turntable high-accuracy pairing bearing, including turntable bearing 1, by the turntable bearing 1 of setting,
It is made of two seat rings, compact-sized, the accuracy of manufacture is high, fit-up gap is small, requires installation accuracy high, and turntable bearing 1 is arranged
There is outer ring 2, mounting hole 4 is uniformly provided at the top center of outer ring 2, the inner wall of outer ring 2 is provided with inner ring 3, outer ring 2 and inner ring
3 junction is provided with mounting groove 5, and mounting groove 5 is provided with roller 6, and the roller 6 by setting is 1:1 cross arrangement, can be simultaneously
Axial force, tilting moment and biggish radial force are born, is widely used in wherein transporting, on engineering machinery and military product,
Outer ring 2 and the upside of inner ring 3 are provided with the first sealing ring 8, outer ring 2 and inner ring 3 and one end of first sealing ring 8 are provided with
Two sealing rings 9, by the first sealing ring 8 and the second sealing ring 9 of setting be on the one hand to the lubricating grease for preventing from having filled to
On the other hand external leakage is dust extraneous in order to prevent, impurity and moisture content intrusion Bearing inner and influence its normal work, outside
The right side of circle 2 is provided with oiling component 7, and inner ring 3 laterally offers consent 13, and consent 13 is provided with plug 10, passes through setting
Plug 10 and consent 13 can reduce the coefficient of friction in 1 motion process of turntable bearing, and guarantee its rotating accuracy, and inner ring 3 is vertical
To fixation hole 14 is offered, fixation hole 14 is provided with plug pin 11, and inner ring 3 and the junction mounting groove 5 of outer ring 2 are provided with holding
Frame 12 is worked by the turntable bearing 1 of setting due to being under heavy-duty low-speed mostly, and rubber enclosure-type structure itself has knot
The advantages that structure is simple, occupies little space, and sealing performance is reliable and be widely used, but its shortcoming is in high temperature shape
Rubber seal lip easy premature ageing when state and loss of seal, therefore the turntable bearing to work under the conditions of worst hot case preferably uses fan
The sealing of palace formula.
Utility model works process: in use, before turntable bearing 1 is installed, will first check the mounting surface of host,
It is required that supporting member should have enough intensity, joint face should be machined, surfacing no-sundries and burr, for that can not carry out
Machining reaches required flatness, filler can be made using the big special plastics of injection intensity, to guarantee to install
The precision of plane and to vibration damping, the lasso of turntable bearing 1 have the soft zone of quenching, this has label " S " on the end face of lasso,
The soft band position should be made to be placed in non-loading zone or occasionally loading zone (consent 13 is always located at soft band) when installation, turntable is installed
When bearing 1, answer advanced row radial positioning, intersection tightens installation bolt, and checks the revolution situation of bearing, by mounting hole 4 into
Row installation drives 6 turns of roller by the effect of frictional force when outer ring 2 starts to rotate in an anti-clockwise direction under the action of torque
Dynamic, since there are angles between the axis and raceway axis of roller 6, the movement of roller 6 is broken down into two parts, i.e., around axis
Rotation and moving along axis.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
