1), use machined into bearing inner race and inner ring outer spherical surface, inner ring convex spheroid machining precision is 0.1mm;
2), with numerical control milling machine process inner ring outer spherical surface, machining accuracy is 0.02mm;
3), use machined into bearing outer ring and outer ring inner ball surface, outer ring inner sphere working precision is 0.1mm;
4), with numerical control milling machine process outer ring inner ball surface, machining accuracy is 0.02mm;
5), by PTFE(teflon) matrix and 808 glue are made into bonding strip, are pasted onto in the bearing outer ring inner ball surface that processes;
6), by bearing outer ring cut a seam vertically, bearing inner race is pushed in bearing outer ring; And
7), mounted joint shaft bearing is placed in lock ring ring, banding lock ring ring closes to bearing outer ring, lock ring ring is put into heating box together with joint shaft bearing and carries out heating cure process, solidifying temperature 80 ~ 120 degrees Celsius, 2.5 ~ 6.5 hours curing times, be down to after room temperature until temperature and take out, remove lock ring ring, solidification process completes.
Beneficial effect of the present invention is: change the mode that original manual brush coating pastes matrix into polymeric matrix bonding strip, improve product self-lubricating quality, decrease raw-material consumption, after bearing inner race installation, with lock ring, outer ring banding is cured process, prevents outer ring to be heated foreign minister Shi Xiang, make it to borough chief, improve matrix and outer ring Adhesion force, improve quality and the working life of bearing.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the sectional view of polymeric matrix bonding strip described in the embodiment of the present invention.
In figure:
1, PTFE base layer; 2,808 glue layers; 3, protection film.
Embodiment
The production method of a kind of high-precision polymer substrate joint shaft bearing described in the embodiment of the present invention, comprises the following steps:
1), use machined into bearing inner race and inner ring outer spherical surface, inner ring convex spheroid machining precision is 0.1mm;
2), with numerical control milling machine process inner ring outer spherical surface, machining accuracy is 0.02mm;
3), use machined into bearing outer ring and outer ring inner ball surface, outer ring inner sphere working precision is 0.1mm;
4), with numerical control milling machine process outer ring inner ball surface, machining accuracy is 0.02mm;
5), by PTFE matrix and 808 glue be made into bonding strip, be pasted onto in the bearing outer ring inner ball surface that processes;
6), by bearing outer ring cut a seam vertically, bearing inner race is pushed in bearing outer ring;
7), mounted joint shaft bearing is placed in lock ring ring, banding lock ring ring closes to bearing outer ring, lock ring ring is put into heating box together with joint shaft bearing and carries out heating cure process, solidifying temperature 110 degrees Celsius, 4 hours curing times, be down to after room temperature until temperature and take out, remove lock ring ring, solidification process completes; In solidification processing procedure, tight by lock ring hoop outside bearing outer ring, inwardly can only grow after bearing outer ring is heated, make bearing outer ring and PTFE substrate adhesive better effects if.
As shown in Figure 1, PTFE matrix is made into bonding strip in advance, and described bonding strip comprises PTFE base layer 1,808 glue layer 2 bonding successively and protection film 3.During making, according to the size of bearing outer ring inner ball surface, PTFE matrix bonding strip is cut into corresponding size.During use, protection film 3 is torn, 808 glue layers 2 are pasted onto in bearing outer ring inner ball surface.
Above-described embodiment is the preferred embodiment of the present invention, and the result of other mode of executions is as follows:
The different glue material deck watch of table 1
| Glue material | The Adhesion force of glue | Other factors such as Costco Wholesale | Overall merit |
| 502 glue | Below 1cps is poor | Low price cost is low | Difference |
| 558 glue | Below 200cps is general | Price general cost is general | Generally |
| 808 glue | 2000cps is with first-class | Price general cost is general | Good |
| Water-soluble gilding glue | 2000cps is with first-class | Price cost is high | Better |
As shown in table 1, the Adhesion force of 502 glue and 558 glue is lower, and overall merit is bad; Adhesion force and 808 glue of water-soluble gilding glue are more or less the same, but its price is more expensive, causes cost of production to increase, and therefore select 808 glue to make viscose glue.
Result deck watch is solidified under table 2 different time different temperatures
