Abstract
The invention discloses an assembly technology of a bearing box of a crystalline silicon slicer, which comprises the steps as follows: a, a bearing outer ring is cooled to a temperature of minus 10 degrees Celsius in a freezing manner, and the frozen bearing outer ring is pressed into a bearing hole on a bearing box body by using an oil press; b, a bearing inner ring is heated to a temperature of 120 degrees Celsius in an electromagnetic induction heating manner and is then sleeved on a transmission shaft; and c, the transmission shaft on which the bearing inner ring is sleeved is loaded into the bearing box body loaded with the bearing outer ring. By using the assembly technology, the assembly precision and the assembly efficiency of a bearing of the crystalline silicon slicer can be improved, so the mounting of the bearing is simple and easy.
Description
Technical field
The present invention relates to a kind of crystalline silicon slicer bearing housing assembly technology.
Background technology
The used bearing enclose of crystalline silicon slicer bearing housing is separable structure at present; Existing assembly method is to increase the bearing aperture on the casing through the thermal expansion casing; Again bearing outer ring is beaten and accomplish assembling; But this method inefficiency is very big to the precision influence of bearing, influences its assembly precision and process efficiency; And the outer ring also has and struck bad risk, and the increase of cost and the overall performance influence of equipment cause cutting into slices. can not be stressed that the enterprise of crystalline silicon section cheaply accepts.
Summary of the invention
The technical problem that the present invention will solve is: overcome the deficiency in the prior art, a kind of easy for installation, the crystalline silicon slicer bearing housing assembly technology that can guarantee the bearing installation accuracy is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of crystalline silicon slicer bearing housing assembly technology; Have following steps: a, bearing outer ring is cooled to-10 degrees centigrade through freezing mode, the bearing outer ring after freezing is pressed in the dead eye on the bearing housing with hydraulic press; B, bearing inner race is heated to 120 degrees centigrade through the electromagnetic induction heating mode, then bearing inner race is enclosed within on the power transmission shaft; C, the power transmission shaft that will be with bearing inner race are packed into and are equipped with in the bearing housing of bearing outer ring.
Specifically, the cooling time of described bearing outer ring is five hours, and freezing equipment is a refrigerator-freezer; Be one minute the heat time heating time of described bearing inner race, and firing equipment is an electromagnetic induction heater.
The invention has the beneficial effects as follows: the present invention can improve crystalline silicon slicer bearing assembly precision and efficiency of assembling, makes the installation of bearing simple, easily.
The specific embodiment
Assembly technology with the NU2228 bearing is an example, and the present invention is further described.
A kind of crystalline silicon slicer bearing housing assembly technology has following steps: a, the NU2228 bearing outer ring is put into refrigerator-freezer, cooling time is five hours; Cool to-10 degrees centigrade; This moment, bearing outside diameter dwindled 10 microns, with hydraulic press the bearing outer ring after freezing was pressed in the dead eye on the bearing housing, and the pressure that is pressed into of hydraulic press is 400N; Pressure stroke is 200mm, and accomplishing the assembling back, to measure the bearing precision of beating be 6 microns; B, the mode of NU2228 bearing inner race through electromagnetic induction heater heating was heated to 120 degrees centigrade in one minute, the bearing inner race internal diameter enlarges 10 microns, then bearing inner race is enclosed within on the power transmission shaft, and accomplishing the assembling back, to measure the bearing precision of beating be 6 microns; C, the power transmission shaft that will be with bearing inner race are packed into and are equipped with in the bearing housing of bearing outer ring, accomplish whole assembling process.
Routine as a comparison with the original assembly technology of NU2228 bearing.
At first with bearing housing heating one hour, make casing upper bearing (metal) aperture enlarge 10 microns, the mode of knocking is by hand knocked the NU2228 bearing outer ring in the dead eye, and whether bearing puts in place relies on sensation to judge, accomplishing the assembling back, to measure the bearing precision of beating be 12 microns; Secondly the NU2228 bearing inner race is put into baking oven heating one hour to 200 degrees centigrade, the bearing inner race internal diameter enlarges 10 microns, and bearing inner race is enclosed within on the power transmission shaft, and accomplishing the assembling back, to measure the bearing precision of beating be 12 microns; The power transmission shaft that will be with bearing inner race is at last packed into and is equipped with in the bearing housing of bearing outer ring, accomplishes whole assembling process.
From above embodiment and Comparative Examples, can find out that use assembly technology according to the invention that the bearing housing of crystalline silicon slicer is installed, to the casing not damaged, assembly precision is high, assembling speed is fast; And original assembly technology causes box deformation easily and influences whole assembly precision because bearing housing need heat, and too high will material being exerted an influence of bearing inner race heating-up temperature reduced assembly precision simultaneously, and the whole assembling process time is long, and efficient is lower.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
