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
[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 , figure 2 As shown, the ring sleeve 1 is included, and the bearing inner ring 3 is installed on the outer circumference of the ring sleeve 1. The outer wall of the ring sleeve 1 is symmetrically arranged with an arc-shaped cooling groove 2 relative to its center, and the arc-shaped cooling groove 2 is arranged along the central axis of the ring sleeve 1. , which is surrounded by the inner wall of the bearing inner ring 3 to form a heat dissipation through hole 4, including an inwardly recessed main arc portion 21 and a side arc portion 22 located at both ends of the main arc portion 21 and protruding outward. The main arc portion The central angle of 21 is greater than the central angle of side arc 22; waist-shaped cooling holes 5 are provided on the collar 1 between adjacent arc-shaped cooling grooves 2.

The invention relates to a cooling installation ring sleeve of a bearing. According to the cooling installation ring sleeve, a bearing inner ring is arranged on the periphery of a ring sleeve; arc-shaped heat emission grooves are symmetrically arranged on the outer wall of the ring sleeve around the center of the ring sleeve; the arc-shaped heat emission grooves are arranged in a through-out manner along the central axis of the ring sleeve; heat emission through holes are formed via enclosure of the arc-shaped heat emission grooves with the inner wall of the bearing inner ring; each heat emission through hole comprises a main arc-shaped part and two side arc-shaped parts, the main arc-shaped part is concaved inwards, and the two side arc-shaped parts are arranged on the two ends of the main arc-shaped parts and protrude outwards; and the central angle of the main arc-shaped part is larger than that of the side arc-shaped parts. According to the cooling installation ring sleeve, the arc-shaped heat emission grooves are arranged on the periphery of the ring sleeve, after installation of the bearing inner ring, the heat emission through holes are formed between the arc-shaped heat emission grooves and the bearing inner ring, so that bearing heat dissipation effect in high speed rotating is improved greatly, and bearing service life is prolonged; the structure is simple; and the cooling installation ring sleeve is convenient for installation.
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 cooling installation ring, 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, the present in...
