Technical field
The present invention relates to a kind of gas turbine bearings, specifically design a kind of axis of the retainer outer diameter with lock claw
It holds.
Background technique
Gas turbine is widely used in the energy, national defence, the field of traffic such as power generation, ships and railroad traction, pipe pressurizing, is
The high-tech Core equipment of relationship national security and the national economic development.The research of gas turbine bearing directly affects gas turbine
Development, gas turbine to bearing requirements one to very high, wherein require bearing that there are the performances such as high revolving speed, long-life, high temperature resistant,
There is very high requirement to the revolving speed of bearing, service life, reliability etc..
Summary of the invention
Based on to the lightweight of gas turbine bearing, the requirement of stability, mesh of the invention is to provide a kind of retainer outer diameter
Bearing with lock claw improves bearing quality on the basis of ensuring the performance of bearing.
In order to achieve the above objectives, the technical scheme adopted by the invention is as follows: a kind of retainer outer diameter has the bearing of lock claw,
Including inner ring, outer ring, roller and retainer；Retainer is set between the inner ring and outer ring, and roller is maintained at by retainer
Between inner ring and outer ring, lock claw is set, lock claw is two, and two lock claw are separately positioned on window on the window beam of the retainer outer diameter
The two sides of beam axial direction.
Further, the lock claw is fish tail type, and fish tail type lock claw is perpendicular to retainer window beam.
Further, the head of the fish tail type lock claw is vertical with retainer window beam connect, and the tail portion of fish tail type lock claw is
Aerofoil profile bending claws, aerofoil profile bending claws extend the two sides of retainer window beam circumferential direction.
Further, the width on the head of the fish tail type lock claw and retainer window beam is of same size.
Further, the aerofoil profile bending claws and rolling element roll the inner surface of face contact as arcuate surface, and circular arc
Shape surface is matched with the rolling surface of rolling element.
Further, the pocket hole of the retainer is straight pocket hole.
Further, the bearing inner ring interior diameter is evenly distributed with several arc-shaped oil grooves.
Further, the axial width of the inner ring is greater than the axial width of outer ring.
Further, the inner ring outer diameter is provided with square oil groove, and the part that inner ring exceeds outer ring is arranged in square oil groove,
Uniformly distributed step type oilhole in square oil groove.
The invention has the benefit that retainer is made of the special-shaped pawl of ring section and outer diameter, such solid cross-section compared with
It is narrow, have the characteristics that light-weighted.The centrifugal force of retainer is small under high revolving speed, and retainer stability is good, and play is small.

Specific embodiment
In order to be more clear the structure and function of invention, the present invention is made into one in the following with reference to the drawings and specific embodiments
Walk explanation.
A kind of retainer outer diameter has the bearing of lock claw, including inner ring 1, outer ring 2, roller 3 and retainer 4；The inner ring 1
Retainer 4 is set between outer ring 2, and roller 3 is maintained between inner ring 1 and outer ring 2 by retainer 4,4 outer diameter of retainer
Window beam 9 on lock claw 5 is set, lock claw 5 is two, and two lock claw 5 are separately positioned on the axial two sides of window beam 9.Retainer 4 is by ring
The special-shaped pawl of tee section and outer diameter composition, such solid cross-section is relatively narrow, has the characteristics that light-weighted.
Further, the lock claw 5 is fish tail type, and fish tail type lock claw is perpendicular to retainer window beam 9.
Further, the head of the fish tail type lock claw 5 is vertical with retainer window beam 9 connect, the tail portion of fish tail type lock claw
For aerofoil profile bending claws 6, aerofoil profile bending claws 6 extend the two sides of retainer window beam circumferential direction.
Further, the width on the head of the fish tail type lock claw and retainer window beam 9 is of same size.Guarantee lock claw with
Retainer window beam stable connection.
Further, the aerofoil profile bending claws 6 roll the inner surface of face contact with roller 3 as arcuate surface, and circular arc
Shape surface is matched with the rolling surface of roller.
Further, the pocket hole of the retainer is straight pocket hole.
Pocket hole is straight pocket hole, and the inner surface that outer diameter aerofoil profile bending claws and rolling element roll face contact is arcuate surface, is had
Stablize the function of rolling element.Aerofoil profile bending claws can keep rolling element, limit the movement of the centre of gyration.Under high revolving speed retainer from
Mental and physical efforts are small, and retainer stability is good, and play is small.
Further, the bearing inner ring interior diameter is evenly distributed with several arc-shaped oil grooves 7.
Further, the axial width of the inner ring is greater than the axial width of outer ring.
Further, the inner ring outer diameter is provided with square oil groove 8, and the portion that inner ring exceeds outer ring is arranged in square oil groove
Point, uniformly distributed step type oilhole 10 in square oil groove.
Bearing inner ring interior diameter is evenly distributed with many arc-shaped oil grooves, and lubricating oil is facilitated to pass through and radiate, in structure, bearing inner race
It is wide compared with outer ring, and in the part that width goes out, design has square oil groove, the uniformly distributed step type oilhole in square oil groove.
P4 grades have been selected in terms of bearing accuracy.
Listed above is only highly preferred embodiment of the present invention.It is clear that the invention is not restricted to which above embodiments, can also have
Many deformations.All deformations that those skilled in the art directly can export or associate from present disclosure,
It is considered as protection scope of the present invention.
