Abstract
The invention discloses a method for machining a tilting type bearing bush and aims to solve the problem that the conventional tilting type bearing bush has instable quality and low production efficiency. The method is characterized by comprising the following steps of: 1, forging a bush blank and dehydrogenating; 2, roughly machining the blank on a lathe, performing finish turning on an alloy and casting an inner wall; 3, casting Babbitt metal; 4, remaining machining allowance except an excircle, and machining the other parts on the lathe to meet a design requirement; 5, marking a radial central line on an end face of the bearing bush, and marking the position of a limiting hole on a bush back; 6, drilling the limiting hole; 7, positioning by using a bearing bush plane and a bearing bush inner hole, and performing finish machining on the arced bush back of the bearing bush on a numerical control milling machine by taking the radial central line as reference of a circumferential direction; and 8, performing linear cutting on the bearing bush to obtain five bush blocks by taking the bearing bush plane and the bearing bush inner hole as reference and taking the radial central line as the reference of the circumferential direction.
Description
Technical field
The present invention relates to a kind of processing method of bearing shell, in particular for the processing method of a kind of tilting-type bearing shell of high-speed gear box.
Background technology
The tilting-type bearing shell that is used for high-speed gear box is generally formed (as shown in Figure 1) by five tile fragments.At present, processing method commonly used is that line cuts its arc watt behind, fine finishining bearing shell internal diameter again, and obvious this method can't accurately be controlled arc watt back of the body A angle, a both sides size, cause unstable product quality, and production efficiency is low.
Summary of the invention
The objective of the invention is to provide a kind of and can effectively guarantee machining accuracy in order to address the above problem, and the processing method that can enhance productivity.
Method of the present invention may further comprise the steps:
1. the forging of unbaked tile and dehydrogenation are handled;
2. at lathe roughing blank, finish turning alloy casting inwall;
3. babbitting;
4. remove cylindrical and stay allowance, all the other all are machined to designing requirement on lathe;
5. separated time in the bearing shell end face marks radially marks the spacing hole position at a watt back of the body;
6. brill spacing hole;
7. with bearing shell plane and bearing shell endoporus location, radially middle separated time is the circumferencial direction benchmark, the fine finishining bearing shell arc watt back of the body on CNC milling machine;
8. be benchmark with bearing shell plane and endoporus, radially middle separated time is the circumferencial direction benchmark, and the bearing shell line is cut into five tile fragments.
The invention has the beneficial effects as follows: utilize numerical control device to process watt arc watt back of the body that to incline, simplified the processing method of bearing shell, effectively guaranteed machining accuracy, improved production efficiency.

Among the figure: 1, bearing shell plane, 2, the bearing shell endoporus.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is further described:
Method of the present invention may further comprise the steps:
1. the forging of unbaked tile and dehydrogenation are handled;
2. roughing blank on lathe, finish turning alloy casting inwall;
3. babbitting;
4. remove cylindrical and stay allowance, all the other all are machined to designing requirement on lathe;
5. separated time in the bearing shell end face marks radially marks the spacing hole position at a watt back of the body;
6. brill spacing hole;
7. as shown in Figure 2,, adjust radially middle separated time, the fine finishining bearing shell arc watt back of the body on CNC milling machine with 1 bearing shell endoporus, 2 location, bearing shell plane;
8. be benchmark with bearing shell plane and endoporus, radially middle separated time is the circumferencial direction benchmark, and the bearing shell line is cut into five tile fragments.
