Abstract
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
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 nested structure is installed in the support 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:
Nested structure is installed in the support of a kind of bearing, and including installing set, bearing inner race is installed in the periphery installing set, described installation set
Outer wall has been centrosymmetrically arranged arc fastener hole relative to it, is plugged with the hollow fastening post of band central through hole, tightly in arc fastener hole
Gu the medial surface of post is the intrados matched with arc fastener hole, its lateral surface is the outer arc that the inwall with bearing inner race matches
Face, forms tapering transition structure between intrados and extrados；With dissipating between the inwall of the described outer wall installing set and bearing inner race
Hot annular space.
Further improvement as technique scheme:
The diameter of the lower end of described fastening post is less than the diameter of its upper end, and the lower end of fastening post is with cone arc shape.
The material of described fastening post is copper.
The method have technical effect that:
Installation set is kept apart with bearing inner race by the present invention by fastening post, forms one and dispels the heat annular space, and to fasten post be hollow
Structure, the radiating effect of bearing when substantially increasing 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 fastening post in the present invention.
In figure: 1, set is installed；11, arc fastener hole；2, bearing inner race；3, fastening post；31, intrados；32, outer arc
Face；33, central through hole；4, heat radiation annular space.
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, nested structure is installed in the support of the bearing of the present embodiment, including installing set 1, installs the periphery of set 1
Installing bearing inner race 2, the outer wall installing set 1 has been centrosymmetrically arranged arc fastener hole 11 relative to it, inserts in arc fastener hole 11
Being equipped with the hollow fastening post 3 of band central through hole 33, the medial surface of fastening post 3 is the intrados matched with arc fastener hole 11
31, its lateral surface is the extrados 32 that the inwall with bearing inner race 2 matches, and forms cone between intrados 31 and extrados 32
Shape transition structure；Install between the outer wall of set 1 and the inwall of bearing inner race 2 with heat radiation annular space 4.
In the present invention, fastening post 3 is pyramidal structure, and its mounting stability is high, is difficult to rock during bearing working.
Further, the diameter of the lower end of fastening post 3 less than the diameter of its upper end, the lower end of fastening post 3 with cone arc shape,
Overall tapered fastening post 3, it is easy to assembly.
Further, the material of fastening post 3 is copper, and its wearability is good.
Installation set 1 is kept apart with bearing inner race 2 by the present invention by fastening post 3, forms a heat radiation annular space 4, and fastens
Post 3 is hollow-core construction, thus the radiating effect of bearing when substantially increasing high-speed rotation, extend the service life of bearing, have
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.
