Problems solved by technology
Even if the bearing with the highest precision on the market is selected, if it is not properly adjusted and used, it will fail in a short period of time and cause a lot of waste
The direct loss is a pair of expensive bearings, and the inevitable indirect loss is even greater
[0003] Traditional taper bearings, angular contact, etc. are adjusted with screws on the end cover of the bearing seat. Manual adjustment is difficult. First of all, it is difficult to accurately control the clearance with experience and feel. The most important thing is that this kind of screw adjustment is difficult to lock. Prohibition of strong protection, often can not withstand strong vibration and other impacts, and even cause greater accidents

Embodiment Construction
[0012] In the following, the present invention will be further described through examples in conjunction with the accompanying drawings. A bearing assembly seat that can accurately adjust the gap includes a main shaft 1, an inner end cover 2, four inner end cover screws 3, a bearing assembly seat 5, and a paired inner side bearing. 6 and outer bearing 9, outer threaded bearing outer circle retaining ring 7 and inner thread bearing outer circle retaining ring 8, bearing inner circle spacer 10, tightening nut 11, outer end cover 20 and four M8 outer end cover screws 30 Composition, between the inner side bearing 6 and the outer bearing 9, there are external threaded bearing outer circle retaining ring 7 and internal thread bearing outer circle retaining ring 8. Four adjustment holes 55 are arranged in the middle section of the bearing group seat 5, four M8 screw holes 52 are arranged on the inner end surface of the bearing group seat 5, and four M8 screw holes 502 are arranged on...

The invention relates to a bearing pack seat capable of regulating clearances accurately. The bearing pack seat comprises a principal axis, an inner end cover, at least three inner end cover screws, a bearing pack seat, a paired inner side bearing and an outer side bearing, an outer thread bearing excircle retainer, an inner thread bearing excircle retainer, a bearing inner circle spacer, a tightened nut, an outer end cover and at least three outer end cover screws; the outer thread bearing excircle retainer and the inner thread bearing excircle retainer are arranged between the inner side bearing and the outer side bearing; and when the clearances of a bearing pack increase after the long-term working abrasion, as long as the combining amount of the outer thread bearing excircle retainerand the inner thread bearing excircle retainer is rotated and changed again, the random clearance accuracy of the bearing pack in the bearing can be realized. The invention has the beneficial effectsthat the outer thread bearing excircle retainer and the inner thread bearing excircle retainer are adopted inventively, not only is the bearing clearance accuracy improved and specific technology requirement is satisfied, but also the service life of the bearing can be prolonged.
Description
technical field [0001] The invention belongs to the field of mechanical transmission equipment, and in particular relates to a bearing group seat which can precisely adjust the gap. Background technique [0002] In the field of large-scale mechanical transmission equipment, the service life of bearings often represents the service life of the overall equipment. Especially in fields that have special requirements for bearing clearance accuracy, such as crystal, agate, diamond and other cutting fields, the bearing clearance accuracy is required to be controlled within 0.001 mm. Even if the bearing with the highest precision on the market is selected, if it is not properly adjusted and utilized, it will fail in a short period of time and cause a lot of waste. The direct loss is a pair of expensive bearings, and the indirect loss that inevitably comes with it is even greater. [0003] Traditional taper bearings, angular contact, etc. are adjusted with screws on the end cover o...
