Problems solved by technology
[0002] In the prior art, the bearing is generally connected to the fixed shaft through the inner ring transition. Since the inner ring of the bearing and the fixed shaft are in surface contact, the heat dissipation space is extremely small, and the heat generated when the bearing rotates at high speed cannot be removed in time, so it is easy to be heated. Wear and tear, its service life is short and needs to be replaced in time, otherwise it will cause certain safety accidents

Embodiment Construction
[0014] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0015] like figure 1 , figure 2 As shown, the supporting mounting sleeve structure of the bearing in this embodiment includes a mounting sleeve 1, the bearing inner ring 2 is installed on the outer periphery of the mounting sleeve 1, and the outer wall of the mounting sleeve 1 is symmetrically arranged with arc-shaped fastening holes 11 relative to its center. A hollow fastening column 3 with a central through hole 33 is inserted in the fastening hole 11. The inner surface of the fastening column 3 is an inner arc surface 31 that matches the arc-shaped fastening hole 11, and the outer surface is an inner arc surface that matches the inner surface of the bearing. The inner wall of the ring 2 coincides with the outer arc surface 32, and a tapered transition structure is formed between the inner arc surface 31 and the outer arc surface 32; th...

The invention relates to a supporting installation sleeve structure for a bearing. The supporting installation sleeve structure for the bearing comprises an installation sleeve; a bearing inner ring is installed on the periphery of the installation sleeve; arc-shaped fastening holes are symmetrically formed in the outer wall of the installation sleeve relative to the center of the installation sleeve; fastening columns are inserted in the arc-shaped fastening holes; the inner side faces of the fastening columns are inner arc faces matched with the arc-shaped fastening holes; the outer side faces of the fastening columns are outer arc faces matched with the inner wall of the bearing inner ring; a conical transition structure is formed between the inner arc faces and the outer arc faces; and a cooling ring gap is formed between the outer wall of the installation sleeve and the inner wall of the bearing inner ring. According to the supporting installation sleeve structure for the bearing, the installation sleeve is isolated from the bearing inner ring through the fastening columns, the cooling ring gap is formed, the cooling effect of the bearing during high-speed rotation is greatly improved, and therefore the service life of the bearing is prolonged, and the beneficial effects of a simple structure and convenient installation are achieved.
Description
technical field [0001] The present invention relates to bearings, in particular to mounting seats for bearings. Background technique [0002] In the prior art, the bearing is generally connected to the fixed shaft through the inner ring transition. Since the inner ring of the bearing and the fixed shaft are in surface contact, the heat dissipation space is extremely small, and the heat generated by the high-speed rotation of the bearing cannot be removed in time, so it is easy to be heated. Wear and tear, its service life is short, need to be replaced in time, otherwise also can cause certain safety accident. Contents of the invention [0003] The applicant researches and improves the above-mentioned shortcomings of the prior art, and provides a bearing support installation sleeve structure, which is installed with a large gap, which greatly improves the heat dissipation effect of the bearing and prolongs the service life. [0004] In order to solve the above problems, th...
