The Z shaft screw is close to the motor and is equipped with 3 angular contact bearings. There are 2 bearings under it. Ask experts to teach me how to install, the top 3 how to arrange, the following 2 how to arrange, thank you!
The following two big faces, the two should be connected in series; the three above two and the two below are Shun Zi; that is to say, the four of them are connected in series; the top one is face-to-face
Would you like to ask about the installation method or the arrangement of the bearings?Installation method: there are mechanical, heating and hydraulic methods of three, when the main choice of the size of the bearings.The method of arrangement is to look at the "V" mark of the outer diameter of the bearing.
There are 3 bearings. Generally not 4, that is, 2. Angular contact bearings are marked on each side. Are generally installed back-to-back. The bearings are facing outwards.Some may pretend to be face-to-face. The two bearings, such as the made in China Harbin and the NSK, are put together. Back to a V word, like the NSK, the installation time is generally inverted V. The point in the direction of the screw.Extended introduction:Bearing (Bearing) is an important component of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement and guarantee its rotation accuracy.According to the friction property of the moving element, the bearings can be divided into two kinds: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimensions, vibration and noise are relatively large, and the price is higher.Generally, the rolling bearings are composed of four parts: the outer ring, the inner race, the rolling body and the cage. According to the shape of the rolling element, the rolling bearings are divided into two major categories: ball bearings and roller bearings.
The following 2 bearings are back to back, but the top one is on the opposite side and the two is on the opposite!!
