Jiaxing bearing group, bearing and shaft

There is rotational, have HRB bearing ( ) Jiaxing bearing group, bearing and shaft. Jiaxing bearing group sales co. , LTD. ( The company) Is in jiaxing bearing group set up by the spot sales window, specializing in HRB brand bearings, existing stocks of 50 million yuan, covers the whole bearing, have very strong cash supply ability. Fitting clearance of bearing and the shaft must be appropriate, radial clearance test can adopt the following methods. 1, the ruler test for larger diameter bearing, gap is larger, with a narrow feeler direct detection. For small diameter of the bearing, clearance is lesser, inconvenience with feeler, bearing clearance, however, must use the thickness of the appropriate feeler. 2, pressure lead test method to detect bearing by pressing lead clearance was detected using feeler, accurately but more trouble. Aluminium wire used in the test should be soft, shoulds not be too big or too small in diameter, the diameter of the ideal of clearance of 1. 5 ~ 2 times, the actual work showed soft lead wire for testing. Detection, first open the bearing cover, the diameter of the lead wire, appropriate to cut it into 15 ~ 40 mm long segments, on the shaft neck and upper and lower bearing interface, cover the bearing cover, tighten the retaining bolt torque by the regulation, unscrew the bolt, then remove the bearing cover, micrometer is used to inspect flattening lead wire thickness, and the average of the top bearing clearance. If the top gap is too small, can add pad on the surface of the upper and lower tile combination. If too large, the reduction of pad, scraping the inquiry or watering the tile again. Adjustment of bearing force: in order to prevent the bearing shell may occur in the process of job rotation and axial movement, besides the fit interference and stop parts, bearing bush must also to compaction with bearing cover, tip clearance method, measurement method and measure the thickness of the soft lead wire, can be used to calculate the bearing force ( With the elastic deformation of axle bush compressed volume) General bearing pressure force at 0. 02 ~ 0. 4 mm. If the clamp force do not conform to the standard, usable increase or decrease of the bearing and bearing joint surface of the gasket thickness method to adjust, tile back no padded. Sliding bearing in addition to to ensure the radial clearance, should also guarantee the axial clearance. Detection of axial clearance, remove the shaft to an extreme position, and then measured with a feeler dial indicator or shaft position from one extreme to another extreme position of channeling momentum namely axial clearance. When the clearance is not in conformity with the provisions of the sliding bearing, should be adjusted. Often use shim adjustment of open type bearing radial clearance, Tip clearance) 。 24-hour customer service hotline: if you are more interested in jiaxing bearing group introduced industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - - - - - - - - - - - - - - - - Editor: HRB bearing company sourcing consultant LTD.
