Corresponding more and more higher.The impact of the overall performance on equipment for the bearing is also huge, is also that equipment is susceptible to fault damage
Parts, bearing is widely used in the every field of national economy, plays increasingly in the industrial construction of whole country
Important effect.
From the production of bearing, China oneself become be only second to Sweden, mouth this, world's bearing of the U.S. and Germany raw
Produce big country；But it is raw from product new varieties ability, product quality level and the manufacturing horizontal Lai Kan China and world's bearing
Producing makes the country prosperous to compare there is also very big gap.
Bearing mnanufacture equipment is to be not only the lifting relating to China's bearing industry manufacture level, and relates to China's weight
The manufacture level of big technical equipment.In the urgent need to promoting manufacture and the level of processing of bearing on market, research and develop corresponding bearing and add
Construction equipment, to meet the great neck of the national economy such as high ferro, automobile, boats and ships, high-grade numerical control device, space flight and aviation, communications satellite
The demand to high-end high-quality bearing for the territory.Bearing due to its special requirement have lasso rigidity poor, processing when deformation, surface
Being easily formed the feature of surface residual stress, own finished surface residual stress is that thin bearing is deformed and the defective workmanship such as cracking
Main cause, residual stress internal after processing then by have influence on corrosion resistance, fatigue strength and the fatigue life of material with
And the various mechanical performance such as reliability.Owing to processing stress deformation, fixture clamping deformation, residual stress become in process
These deformed cross such as shape, heat in metal cutting deformation are complicated, interact, and are continually changing in time, directly or indirectly have influence on axle
The precision held, performance, life and reliability.
The processing to bearing channel surface strength for traditional surface processing technique can not meet now for high-quality
The demand of bearing.The utility model combines electromagnetism reinforcement technique and proposes a kind of electricity for improving ball bearing channel surface strength
Magnetic strength gasifying device.
Content of the invention
For solving the problems referred to above, the utility model provides a kind of electromagnetism strengthening for improving ball bearing channel surface strength
Device, to improve the surface strength of bearing further, extends the service life of bearing.For solving the problems referred to above, the utility model
There is provided a kind of electromagnetism intensifying device for improving ball bearing channel surface strength, it is characterised in that include bearing holder (housing, cover), bolt, line
Circle, coil clamping plate, bracing frame, the pulse power and workpiece, described bearing holder (housing, cover) is by the sleeve combination of inside and outside two-layer different materials
Forming, workpiece is bolted the center at bearing holder (housing, cover), and described coil diameter is identical with the width of bearing outer ring channel,
Coil two ends are connected on pulse power generator respectively, and described coil clamp is bolted on bracing frame, coil clamp
Tool can accommodate the coil of the different size bigger than its internal diameter.
Compared with prior art, a kind of electromagnetism intensifying device for improving ball bearing channel surface strength of the utility model
Advantage be: be applied to electromagnetism metal-surface strengthening technique in actual production, the table of bearing outer ring channel can be increased substantially
Face intensity, improves the microstructure of bearing outer ring channel, extends the service life of bearing, and the coil clamp of this device can be easy to root
According to bearing outer ring channel size more emat coil, and easy accessibility.
