Abstract
The invention discloses a machining method of a hub bearing. The machining method of the hub bearing comprises the following steps: (1) feeding; (2) chamfering end surfaces; (3) grinding the end surfaces; (4) piercing; (5) chamfering an oil injection hole; (6) carrying out thermal refining; (7) carrying out centerless grinding; (8) extruding; and (9) grinding surfaces and the like. Compared with the prior art, the machining method of the hub bearing has the beneficial effects that the size and the weight of the hub bearing machined by the method are reduced effectively, meanwhile, load is increased, the service life of the hub bearing is prolonged, the overall quality of the hub baring is improved, and the production cost is relatively low.
Description
Technical field
The present invention relates to hub bearing technical field, be specifically related to the processing side of a kind of hub bearing
Method.
Background technology
The Main Function of hub bearing is load-bearing and the rotation offer accurately guiding for wheel hub, and it was both
Bear axial load and bear again radial load, be very important parts.Hub bearing
By the relative motion of axle and bearing, oil is brought between two surfaces, forms enough pressure membrane,
Two surfaces are separated, thus bears load.Under the conditions of hydrodynamic lubrication, slidingsurface is lubricated
Oil separately does not occur directly to contact, it is also possible to be greatly reduced friction loss and surface abrasion, oil
Film also has certain vibration absorption ability.But starting friction resistance is bigger.
Summary of the invention
It is desirable to provide the processing method of a kind of hub bearing.
The present invention provides following technical scheme:
The processing method of a kind of hub bearing, comprises the following steps:
(1) blanking: the original blank of blanking is tubulose bar, according to hub spindle on sawing machine
Original blank is cut by the length held, and obtains the primary blank of hub bearing, described original blank
External diameter 0.2mm bigger than the external diameter of hub bearing final products, the internal diameter ratio of described original blank
The little 0.2mm of internal diameter of hub bearing final products；
(2) end chamfer: two end faces of described hub bearing are carried out chamfer machining；
(3) cross grinding: two end faces of hub bearing are carried out grinding on surface grinding machine
Processing；
(4) punching: have oil filler point on the sidewall of hub bearing, hub bearing is fixed on
On punch press, punch process mode is used to produce described oil filler point；
(5) oil filler point chamfering: utilize chamfering device, processes chamfering on described oil filler point；
(6) modifier treatment: be modulated hub bearing processing, to improve its combination property；
(7) centreless grinding: on centerless grinder, is not in the mood for the surfaces externally and internally of hub bearing
Mill processing, makes obtained blank external diameter 0.05mm less than the external diameter of hub bearing final products,
Described blank internal diameter 0.05mm less than the internal diameter of hub bearing final products；
(8) extruding: on forcing press, squeezes circular core in the internal diameter of hub bearing
Press and pass through, the external diameter 0.02mm bigger than the internal diameter of hub bearing final products of described core,
The material of described core is wolfram steel material, and hardness is HRC 80；
(9) surface grinding: hub bearing is placed in spiral vibrating finishing machine and is ground.
Compared with prior art, the invention has the beneficial effects as follows: the hub bearing of present invention processing
Effectively reducing volume and weight, increase load simultaneously, the present invention improves hub bearing
Service life and overall quality, production cost is relatively low.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
