Looking for Yuwei for insulation

Release time: May 18, 2018 16:08:43 Views: 1863

first Shanghai Yuwei Bearing Co., Ltd Let's learn about mixing Ceramic bearing General situation of

(1) It has high temperature resistance and small thermal expansion coefficient of ceramic ball, which will not cause bearing ball expansion due to temperature in high temperature environment, which greatly improves the service temperature of the whole bearing. The temperature of ordinary bearing is about 160 ℃, and that of ceramic ball can reach above 220 ℃.

(2) Ceramic ball bearing has a high rotational speed of 1.5 times that of ceramic ball bearing

(3) Long service life, ceramic ball can not add any grease, that is to say, even if the grease is dry, the bearing can still operate, so as to avoid the bearing premature failure caused by grease drying out. According to our test and some customer feedback, the service life of the bearing after using ceramic ball is 2-3 times of that of the ordinary bearing

(4) The last and most important point is insulation. The bearing with ceramic ball can insulate the inner and outer rings of the bearing. Because the ceramic ball is an insulator, using ceramic ball between the inner and outer rings of the bearing can achieve the effect of insulation. In this way, the bearing can be used in the conductive environment

What is the general appearance of hybrid ceramic bearings?

Bearing steel inner and outer ring + zirconia ceramic ball / silicon nitride ceramic ball

Stainless steel inner and outer ring + zirconia ceramic ball / silicon nitride ceramic ball

What problems can such an assembly solve?

First, increase the speed

Second, prolong the service life

But the bearing is composed of four categories: inner and outer rings of bearing, ball, cage and dust cover. So how can hybrid ceramic bearings be insulated like all ceramic bearings?

The requirement of insulation is that the inner and outer rings of the bearing are not connected. The core of the problem lies in the cage.

The purpose of cage: to isolate and guide the movement of rolling element.

But when the cage is metal, the inner and outer rings of the bearing will be connected, which will lead to the bearing conducting electricity, which will lose part of the significance of ceramic ball.

As shown in the figure below, customer requirements:

1) Bearing high speed, noise requirements in Z2 group

2) The bearing is in the center of magnetic field, and the bearing can rotate flexibly

3) The service life is 2 / 3 longer than the previous all metal bearings

It can be imagined that the bearing meeting the above requirements:

Hybrid ceramic bearing + nylon cage + rubber cover + oil lubrication / dry drying without oil
