Abstract
The invention discloses a method for fitting an angular contact ball bearing and belongs to the technical field of bearing assembly. The method comprises the steps of heating an outer ring (2), cooling an inner ring (4) and fitting to obtain the finished angular contact ball bearing. According to the invention, the fitting rate in one time is effectively improved, the assembly efficiency is also improved, the time and cost are reduced, and the waste bearing which is not fitted properly is avoided.
Description
Technical field
The present invention relates to bearing assemble technical field, especially relate to a kind of trap method of angular contact ball bearing.
Background technique
Known, for trap convenience, on one or two lasso of angular contact ball bearing with slope, but the slope of only having a lasso is the slope with fore shaft, in angular contact ball bearing trap process, conventionally use constant temperature electric furnace heating outer ring to uniform temperature, make outer ring produce thermal expansion, then steel ball is pressed into raceway by the one end, slope with fore shaft, this trap method is to rely on high the choosing and machining accuracy of fore shaft, if fore shaft Gao Tai great, steel ball cannot be pressed in raceway and affect manufacturing efficiency, even if be pressed into, in raceway, also will destroy raceway and produce waste product, if, will there is the sequence of sanqu songs within a particular musical mode after trap and produce waste product in fore shaft Gao Tai little.
Summary of the invention
In order to realize described goal of the invention, the invention discloses a kind of trap method of angular contact ball bearing, described method is used the principle of rising-heat contracting-cold, in heating outer ring 1, inner ring 4 is carried out cooling, can guarantee smooth trap, can guarantee again not occur the sequence of sanqu songs within a particular musical mode after trap; The present invention has effectively improved trap rate one time, has also improved efficiency of assembling, and has saved time and cost, and has avoided the appearance of sequence of sanqu songs within a particular musical mode waste product.
In order to realize the object solving the problems of the technologies described above, the present invention has adopted following technological scheme:
A trap method for angular contact ball bearing, comprises heating outer ring, cooling outer ring and trap, obtains finished product angular contact ball bearing, and concrete steps operation is as follows:
A, heating outer ring
Outer ring is placed on heating equipment and is heated, outer ring is heated and produces expansion;
B, cooling outer ring
Connect previous step, inner ring is placed on cooling unit cooling, make inner ring meet cold generation and shrink;
C, trap
Connect previous step, by the retainer with rolling element, produce the outer ring of thermal expansion and meet the inner ring that cold generation shrinks and carry out trap, obtain finished product angular contact ball bearing.
The trap method of described angular contact ball bearing, the heating equipment in described steps A is the device with heating function, the described device with heating function is electric heater or electric jacket.
The trap method of described angular contact ball bearing, the heating-up temperature in described steps A is 80 ℃-120 ℃.
The trap method of described angular contact ball bearing, the cooling unit in described step B is the device with refrigerating function.
The trap method of described angular contact ball bearing, the chilling temperature in described step B is-20 ℃-0 ℃.
By adopting technique scheme, the present invention has following beneficial effect:
The trap method of angular contact ball bearing of the present invention, described method is used the principle of rising-heat contracting-cold, in heating outer ring 1, inner ring 4 is carried out cooling, can guarantee smooth trap, can guarantee again not occur the sequence of sanqu songs within a particular musical mode after trap; The present invention has effectively improved trap rate one time, has also improved efficiency of assembling, and has saved time and cost, and has avoided the appearance of sequence of sanqu songs within a particular musical mode waste product.
