(2) background technique
The full ball bearing of a kind of thin-wall angle contact is arranged in the market, and this bearing is high performance hydraulic pump special bearing energy of new generation, has the characteristics such as high loading, high rigidity, highi degree of accuracy, low noise.Because the Related product of supporting requirement is not satisfied in the hydraulic pump structure restriction on the market, so needs a kind of auxiliary products badly.
(3) summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, easy to use, high loading, high rigidity, highi degree of accuracy cooperate the full ball bearing of thin-wall angle contact of the full ball bearing of thin-wall angle contact.
The object of the present invention is achieved like this: it comprises outer ring 1, inner ring 2 and steel ball 3, and steel ball 3 is arranged between outer ring 1 and the inner ring 2, and outer ring 1 is connected with bearing saddle bore, and inner ring 2 is connected with axle, and the outer ring is provided with inclined flange, and inner ring is provided with not contour rib.
The present invention also has like this some technical characteristicss:
1, described steel ball 3 comprises one group of steel ball;
2, described inner ring 2, outer ring 1 width difference.
Another object of the present invention is to provide the processing method of the full ball bearing of a kind of thin-wall angle contact, it comprises:
1, Vehicle Processing technological process and allowance step:
(1) outer ring: thin Chefei's basal plane, endoporus, go acute angle → thin car basal plane, external diameter (allowance 0.2 ~ 0.5) → buffing two planes (allowance 0.2 ~ 0.3), the inside and outside angle of external diameter → surface turning → car outer fissure (allowance 0.6 ~ 0.8) → car slope, deburring;
(2) inner ring: thin car basal plane (allowance 0.2 ~ 0.3), rough turn internal diameter (allowance 0.7 ~ 0.9), go interior acute angle → thin Chefei's basal plane, internal-and external diameter to go raceway (allowance 0.5 ~ 0.7) → deburring → heat treatment in the inside and outside acute angle of non-basal plane, outer acute angle → buffing two planes of basal plane → buffing internal-and external diameter (allowance 0.6 ~ 0.8) → thin car internal diameter (allowance 0.6 ~ 0.8) → inside and outside chamfering → car in car two sides;
2, grinding process flow process and allowance step: (take the P4 level as example)
(1) outer ring: corase grind plane (allowance 0.1 ~ 0.2) → corase grind external diameter (allowance 0.1 ~ 0.16) → end mill external diameter (allowance 0.03 ~ 0.06) → lappingout external diameter (allowance 0.003 ~ 0.008) → outer raceway of corase grind (allowance 0.1 ~ 0.15) → fine grinding plane (allowance 0.04 ~ 0.07) demagnetizing and cleaning → mill slope →, grind raceway (allowance 0.01 ~ 0.015) outside outer raceway (allowance 0.04 ~ 0.07) → lappingout eventually;
(2) inner ring: raceway (allowance 0.008 ~ 0.012) → heat treatment in corase grind plane (allowance 0.1 ~ 0.2) → corase grind internal-and external diameter (allowance 0.15 ~ the 0.2) → interior raceway (allowance 0.08 ~ 0. 12) of mill internal-and external diameter (allowance 0.05 ~ 0.07) → lappingout internal diameter (allowance 0.001 ~ 0.003) → corase grind at end → mill internal diameter (allowance 0.04 ~ 0.08) → whole flat surface grinding (allowance 0.04 ~ 0.07) → demagnetizing and cleaning → lappingout;
3, assembly technology step:
Cleaning of Parts → sort trap → assembling trap → play detection → inside and outside footpath measurement → finished product demagnetizing and cleaning → oven dry → oiling, packing → warehouse-in.
1, adopts optimal design, changed the conventional design of common angular contact ball bearing, reasonably adjusted main parameter in the less confined space, adopted without the full ball design of retainer, increased rolling element quantity.Under less sectional area, adopt without the full ball design of retainer, increased a plurality of rolling element quantity, make this series bearing rigidity, load greater than unidimensional wide series product.
2, according to the shaft strength Analysis deterrmination, the wrapping angle of bearing is 40 °; Inside and outside circle width does not wait, the not contour rib of outer ring inclined flange, inner ring.Large wrapping angle can make product namely bear radial load can bear again larger thrust load and radial and axial connected load.Be subjected to sharp direction at bearing working, adopt high rib, opposite side adopts low rib, and the design that do not wait of inner ring, outer ring width, is conducive to bearing lubrication and heat radiation.
3, according to the structure and material performance of bearing, design provides rational lock ball amount δ: the lock ball amount is the key factor in the angular contact ball bearing design, especially for the full ball angular contact ball bearing without retainer.Reasonably lock ball amount δ is that trap play, the bearing material elastic deformation amount according to bearing determines.Reasonably the lock ball amount can improve performance and the manufacturing efficiency of bearing.Because the lock ball amount is excessive: easily hinder steel ball during assembling, the bear vibration noise is increased; The lock ball amount is too small: the easy sequence of sanqu songs within a particular musical mode, reject rate is high.
4, adopt press hardening technique: owing to very easily distortion in the ultralight series product heat treatment process, be the control distortion, adopt press hardening---during soon each lasso is packed a grinding tool into, clamp the amount of deformation of controlling lasso.Reduce reject rate, thereby reduced the cost of bearing, guaranteed the high-precision performance of bearing.
A new generation's high performance hydraulic pump is the Updated product of oil hydraulic pump industry, and market prospects are wide.Exploitation synchronous with it can be grasped more primitive technology, prospective meaning arranged in that the development in this field is supporting.Simultaneously, structure of the present invention is highi degree of accuracy thin-wall bearing scope, and its difficulty of processing is large, and market can not lost easily, and added value is high, and formation is extensively supporting easily, realizes the market efficiency maximization.Because the inside and outside circle width of this ultralight serial bearing does not wait, so that the bearing sectional area is very little, has saved the space of equipment, make compact equipment, volume little, lightweight, receive praises from customers.Employing has increased a plurality of rolling element quantity without the full ball design of retainer, makes this series bearing rigidity, load greater than unidimensional wide series product.Adopt 40 ° of wrapping angles, make product can bear radial load and larger thrust load and radial and axial connected load.Inner ring, outer ring width do not wait, and outer ring inclined flange, inner ring be the design of contour rib not, are conducive to bearing lubrication and heat radiation.Rational lock ball amount δ can improve performance and the manufacturing efficiency of bearing.Because the lock ball amount is excessive: easily hinder steel ball during assembling, the bear vibration noise is increased; The lock ball amount is too small: the easy sequence of sanqu songs within a particular musical mode, reject rate is high.The present invention also adopts press hardening technique effectively to control distortion in the ultralight serial lasso heat treatment process, guaranteed the requirement of bearing highi degree of accuracy, low noise, heavy load, high comprehensive technical performances such as rigidity of support.
