Abstract
Ring set is installed in the cooling that the present invention relates to a kind of bearing, bearing inner race is installed in the periphery of ring set, the outer wall of described ring set has been centrosymmetrically arranged arc radiating groove relative to it, arc radiating groove runs through setting along the central axis of ring set, thermal vias is enclosed between itself and the inwall of bearing inner race, including the minor arc portion inwardly concaved and be positioned at two ends, minor arc portion outwardly arc portion, side, the central angle in minor arc portion is more than the central angle in arc portion, side.In the present invention, the outer peripheral face of ring set arranges arc radiating groove, after bearing inner race is installed, form multiple thermal vias between the two, the radiating effect of bearing when it greatly improves high-speed rotation, thus extend the service life of bearing, there is simple in construction, feature easy for installation.
Description
Technical field
The present invention relates to bearing, particularly to the mounting seat of bearing.
Background technology
In prior art, bearing is typically connected on fixing axle by inner ring transition, owing to being face between bearing inner race and fixing axle
Contact, its heat-dissipating space is minimum, and the heat produced during bearing high-speed rotation cannot be got rid of in time, thus easily thermal wear, its
Service life is shorter, needs to change in time, the most also can cause certain security incident.
Summary of the invention
The applicant, for the disadvantages mentioned above of prior art, studies and improves, it is provided that ring set is installed in the cooling of a kind of bearing,
It uses wide arc gap to install, and substantially increases the radiating effect of bearing, increases the service life.
In order to solve the problems referred to above, the present invention uses following scheme:
Including ring set, bearing inner race is installed in the periphery of ring set, and the outer wall of described ring set has been centrosymmetrically arranged arc heat radiation relative to it
Groove, arc radiating groove runs through setting along the central axis of ring set, encloses thermal vias between itself and the inwall of bearing inner race, bag
Including the minor arc portion inwardly concaved and be positioned at two ends, minor arc portion outwardly arc portion, side, the central angle in minor arc portion is more than arc portion, side
Central angle；The adjacent ring set between arc radiating groove is provided with waist shaped heat dispersing hole.
The method have technical effect that:
In the present invention, the outer peripheral face of ring set arranges arc radiating groove, after bearing inner race is installed, forms multiple heat radiation between the two and leads to
Hole, the radiating effect of bearing when it greatly improves high-speed rotation, thus extend the service life of bearing, have simple in construction,
Feature easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structure chart that the present invention installs bearing inner race.
In figure: 1, ring set；2, arc radiating groove；21, minor arc portion；22, side arc portion；3, bearing inner race；4, heat radiation is logical
Hole；5, waist shaped heat dispersing hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As shown in Figure 1 and Figure 2, including ring set 1, bearing inner race 3 is installed in the periphery of ring set 1, and the outer wall of ring set 1 is wherein
The heart has been arranged symmetrically with arc radiating groove 2, and arc radiating groove 2 runs through setting along the central axis of ring set 1, itself and bearing inner race 3
Inwall between enclose thermal vias 4, including the minor arc portion 21 inwardly concaved and be positioned at two ends, minor arc portion 21 outwardly
Arc portion, side 22, the central angle in minor arc portion 21 is more than the central angle in arc portion, side 22；The adjacent ring set between arc radiating groove 2
1 is provided with waist shaped heat dispersing hole 5.
In the present invention, the outer peripheral face of ring set 1 arranges arc radiating groove 2, after bearing inner race 3 is installed, is formed multiple between the two
The waist shaped heat dispersing hole 5 arranged on the thickening part between arc radiating groove 2 adjacent on thermal vias 4, and ring set 1, carries significantly
The radiating effect of bearing during high high-speed rotation, thus extend the service life of bearing, there is simple in construction, spy easy for installation
Point.
Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not appoints the present invention
What pro forma restriction, has usually intellectual, if without departing from the carried technical characteristic of the present invention in any art
In the range of, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and without departing from this
Bright technical characteristic content, all still falls within the range of the technology of the present invention feature.
