产品的装配

dilatability

 

   轴承的推荐的装配方法有两种，一种是常温压制装配法。另一种是冷却装配法，冷却装配法具有操作方便，配合精度高的优点，在条件具备的情况下，应优先选用。座孔加热的方法由于热量会破坏轴承材料的组织结构所以应避免使用。

 

冷却装配的方法

 

1、  所需材料

冷却介质：液氮或干冰

容器：保温隔热容器

 

2、  冷却后轴承外径收缩量△d的计算

 

△d = d x α x (t-t1)

 

注释：

d:  轴承外径

α：轴承线膨胀系数

t： 轴承冷却温度

t1：装配环境温度

 

3、  操作方法

 

①   将轴承放入保温隔热容器中，放入冷却介质，一般推荐的冷却温度为-40°c~-70°c。

②   冷却时间1小时以上，如果轴承与座孔的过盈量较大时，需要适当延长冷却时间。

③   再次测量轴承的外径与座孔内径的尺寸，便于装配顺利进行。

④   将冷却好的轴承迅速装入座孔中，如果在中途停留时间过长，将造成轴承难以装入。

⑤   在轴承工作表面涂布润滑脂。

⑥   在冬季气温较低时，应让座孔保持在20°c~30°c。

 

installation:

there are two kinds of bearing assembly methods recommended, one is pressing and assembling method at room temperature. the other is a cooling assembly method, cooling assembly method has the advantages of convenient operation, with the advantages of high precision, in the case of conditions, should be preferred. methods the seat hole heating due to the organizational structure of heat will damage the bearing material and should be avoided.

 

method of cooling assembly

 

1, the required materials

the cooling medium: liquid nitrogen or dry ice

container: thermal insulation container

 

2,bushing od shrinked rate (△d) calculate after cooling

△d = d x α x (t-t1)

notes:

d: bearing outside diameter

α: bearing coefficient of linear expansion

t: bearing cooling temperature

t1: assembly environment temperature

 

3, operation method

①   the bearing in the thermal insulation container, into the cooling medium and cooling temperature is generally recommended for-40°c~-70°c.

②the cooling time of 1 hours or more, if the bearing seat hole and the amount of interference is larger, the need for appropriate to extend the cooling time.

③inspect bushing od and housing id again,easy to installation.

④bearing the good cooling rapidly into the seat hole, if long residence time in the middle, will cause the bearing to load.

⑤the working surface of the bearing grease coating.

⑥the low temperature in winter, the seat hole should be maintained at 20°c~30°c.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

产品使用的注意事项

 

1,在设计时尽量选用标准规格，如需采用非标规格，请与我们联系。

2,装配前应清洁轴承内外表面，要求内外表面无杂质、异物。

3,在装配前，若能用润滑油脂涂布于摩擦表面，可缩短摩擦副的走合期。使机械运转更加平稳，延长使用寿命。

4,装配时，建议将轴承与座孔垂直慢慢压入。严禁野蛮敲击，以免引起轴承变形，降低使用寿命。

5,在承载压力较高或往复运动时，建议将轴承与座孔用螺栓固定。

6,轴承使用一段时间后，会在轴承表面形成黑色或灰黑色的润滑膜，请不要擦洗，正常使用。

7,一般说来，轴应选用比轴承硬度高的材料，以保护轴。

 

notice for using

 

1, in the design to the selection of standard specification, if need to use non-standard specifications, please contact us.

 

2, the inside and outside surface should be clean bearing assembly requirements, internal and external surface without impurities, foreign matter.

 

3, in the assembly, if can use grease is coated on the surface of the friction, the friction pair can shorten the running in period. make the machine run more smoothly, to extend the service life.

 

4, the assembly, and bearing seat hole should be vertical pressure slowly into the. no savage knock, so as not to cause the bearing deformation, reduce the service life.

 

5, in the high load bearing pressure or reciprocating motion, bearing and the hole should be fixed with bolts.

 

6, the use of a period of time after the bearing, lubricating film will form a black or dark gray in the bearing surface, do not wash, normal use.

 

7, generally speaking, shaft bearing should be used than the hardness of the material, in order to protect the shaft.
