缓冲托辊制作工艺

Making process of cushion roller

1.轴：用20号冷拔圆钢加工，加工好后去毛刺，两侧轴承挡同心度误差小于0.025mm。

The 1. axis is made from cold drawn round steel No. 20, processed and burrs. The concentricity error of two side bearing blocks is less than 0.025mm.

2.轴承座，内挡圈，外挡圈，挡板等用08F冷压板冲压制成，成品不得有表面拉毛、破裂、裂纹、地面不平等缺陷，缓冲托辊生产厂家，同时需保证内外圆同心度及外形公差尺寸等。

2. bearing seat, internal retaining ring, external retaining ring, baffle and so on are made of 08F cold press plate. The finished product must not have surface pulling, rupture, crack, unequal ground defect, cushion roller manufacturer, and guarantee the internal and external concentricity and shape tolerance.

3.密封圈，内密封圈，外密封圈为尼龙注塑产品，外加工验收时需检查其不得有裂纹、飞边和毛刺，密封环处应平整，其局部低凹缺陷不得大于0.5mm，注塑气泡不得大于0.5mm，每平方厘米不得多于2个，包胶缓冲托辊，总数不得多于5个。在轴向力为1500N时，轴向变形不得超过0.5mm。

3. sealing ring, inner seal ring and outer seal ring are nylon injection products. It should be checked for no crack, flying edge and burr in the external processing acceptance. The seal ring should be flat, its local low concave defect should not be more than 0.5mm, the injection bubble must not be more than 0.5mm, not more than 2 per square centimeter, and the total amount of the rubber cushion roller is not much. 5. When the axial force is 1500N, the axial deformation should not exceed 0.5mm.

4.辊皮：用Q235 钢管加工。

4. roller skin: processing with Q235 steel pipe.

5.轴承，新型缓冲托辊，挡圈，瓦合等为外购件。

The 5. bearing, new buffering roller, retaining ring, tile and so on are purchased parts.

6.橡胶圈，用工业橡胶1260浇制，不允许有气孔、裂纹等缺陷。橡胶耐磨且富有弹性。

The 6. rubber ring is made of industrial rubber 1260. It is not allowed to have holes, cracks and other defects. The rubber is wear-resistant and elastic.

托辊配件的轴承在使用过程中，缓冲托辊，经常会出现被损伤的现象，一般是由于使用太久造成的，也有其它方面的原因造成。为了避免被损伤，就应将相关工作做到位。各加工工艺的正当性、保守性、稳固性也会反应到轴承的寿数。随着冶金技术的退步，原人才质量失去好转。轴承整机正在生产进程中，要通过许多道冷、热加工岁序，为了满意少量量、高频率、质量上乘量的请求，轴承钢应具有良好的加工功能。内中反应废品单向推力球轴承质量的热解决和磨削加工岁序，常常与轴承的生效有着更间接的联系。

The bearing of the accessories of the roller is used in the process of using the cushion roller, which often appears to be damaged, usually due to the use of too long, and other reasons. In order to avoid being damaged, relevant work should be done in place. Right, conservative and stable will response to the bearing life of the machining process. With the retrogression of metallurgical technology, the quality of original talents has been improved. Bearing machine is in the process of production, to pass a lot of cold, hot processing age, in order to satisfy a small amount, high frequency, high quality request, bearing steel should have good processing function. The heat treatment and grinding sequence of internal thrust waste ball unidirectional thrust ball bearings are often more closely related to the effectiveness of bearings.
