Abstract

The present invention relates to the porous mounting ring nested structure of a kind of bearing, including ring set, 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, the central axis of the parallel ring set of arc radiating groove also runs through the axial two ends 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, the middle part in minor arc portion is provided with the through hole at the center of ring set, the tapered structure of through hole.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, plus the multiple through holes axially penetrating through ring set being provided with in arc radiating groove, 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

The porous mounting ring nested structure of bearing
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 the porous mounting ring noose of a kind of bearing Structure, it uses wide arc gap to install, substantially increases the radiating effect of bearing, increase the service life.
In order to solve the problems referred to above, the present invention uses following scheme:
The porous mounting ring nested structure of a kind of bearing, including ring set, bearing inner race, the outer wall of described ring set are installed in the periphery of ring set Relatively it has been centrosymmetrically arranged arc radiating groove, and the central axis of the parallel ring set of arc radiating groove also runs through the axial two ends of ring set, Thermal vias is enclosed, including the minor arc portion inwardly concaved and be positioned at two ends, minor arc portion outwards between itself and the inwall of bearing inner race The arc portion, side protruded, the central angle in minor arc portion is more than the central angle in arc portion, side, and the middle part in minor arc portion is provided with the center of ring set Through hole, the tapered structure of through 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, adds the multiple through holes axially penetrating through ring set being provided with in arc radiating groove, and when it greatly improves high-speed rotation, bearing dissipates Thermal effect, thus extend the service life of bearing, there is 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, through 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, the porous mounting ring nested structure of the bearing of the present embodiment, including ring set 1, the periphery peace of ring set 1 Dress bearing inner race 3, the outer wall of ring set 1 has been centrosymmetrically arranged arc radiating groove 2, the parallel ring set of arc radiating groove 21 relative to it Central axis and run through the axial two ends of ring set 1, enclose thermal vias 4 between itself and the inwall of bearing inner race 3, including The minor arc portion 21 that inwardly concaves and be positioned at two ends, minor arc portion 21 outwardly arc portion, side 22, the central angle in minor arc portion 21 is big In the central angle in arc portion, side 22, the middle part in minor arc portion 21 is provided with the through hole 5 at the center of ring set 1, the tapered knot of through hole 5 Structure.
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 Thermal vias 4, adds the multiple through holes 5 axially penetrating through ring set 1 being provided with in arc radiating groove 2, it greatly improves and turns at a high speed The radiating effect of bearing time dynamic, thus extend the service life of bearing, there is simple in construction, feature easy for installation.
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.
