Abstract
The utility model provides a kind of main fulcrum structure of the rotor of double-row bearing, including two bearings (3), central oil pipe (2) and clearance adjuster (1), bearing (3) is ball bearing, two bearings (3) and clearance adjuster (1) are sleeved between axis (4) and bearing block (5), wherein clearance adjuster (1) is between two bearings (3), to adjust two bearings (3) Internal and external cycle axial position, the clearance adjuster is annular construction member, and inside and outside two circle contradicts respectively with inside and outside two circle of two bearings (3) to connect；Central oil pipe (2) sets through bearing block and is inserted into clearance adjuster (1), it is inserted into the oil outlet that the end set of clearance adjuster (1) one end is useful for lubrication two bearings (3), and oil outlet respectively sets spout at one towards two bearings (3) direction.Under existing bearing conditions, fulcrum bearing capacity is improved by being arranged in juxtaposition for the main fulcrum structure of rotor of double-row bearing provided by the utility model.
Description
Technical field
The utility model belongs to aero-engine field of structural design, more particularly to rotor field, and in particular to Yi Zhongshuan
Arrange the main fulcrum structure of rotor of bearing.
Background technology
The operating of rotor needs fulcrum, and main fulcrum will also undertake possible axial force in addition to radial support is provided for rotor,
A ball bearing, i.e. single row bearings generally are taken, axial force will be controlled in the tolerance range of bearing.But single row bearings are unless more
The bearing of greater degree is changed, otherwise can not improve bearing capacity.
Utility model content
The purpose of this utility model is to provide a kind of main fulcrum structures of the rotor of double-row bearing, overcome or alleviated by existing skill
At least one drawbacks described above of art.
The purpose of this utility model is achieved through the following technical solutions：A kind of main fulcrum structure of the rotor of double-row bearing, if
It puts between axis and bearing block, is set with including two bearings, central oil pipe and clearance adjuster, two bearings and clearance adjuster
Between axis and bearing block, wherein clearance adjuster is between two bearings, to adjust two bearings Internal and external cycle axial position；In
Oil pipe is entreated to be set through bearing block and is inserted into clearance adjuster, the end set for being inserted into clearance adjuster one end is useful for lubricating
The oil outlet of two bearings.
Preferably, the bearing is ball bearing.
Preferably, the oil outlet on the central oil pipe respectively sets spout at one towards the two bearing directions.
Preferably, the clearance adjuster is annular construction member, and inside and outside two circle is respectively with inside and outside two bearings two
Circle, which contradicts, to connect.
A kind of advantageous effect of the main fulcrum structure of rotor of double-row bearing provided by the utility model is, in existing axis
Under the conditions of holding, fulcrum bearing capacity is improved by being arranged in juxtaposition.
Description of the drawings
Fig. 1 is the structure diagram of the main fulcrum structure of rotor of the utility model double-row bearing.
Reference numeral：
1- clearance adjusters, 2- centers oil pipe, 3- bearings, 4- axis, 5- bearing blocks.
Specific embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.In the accompanying drawings, from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Described reality
It is the utility model part of the embodiment to apply example, instead of all the embodiments.Below with reference to the embodiment of attached drawing description
It is exemplary, it is intended to for explaining the utility model, and it is not intended that limitation to the utility model.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
The main fulcrum structure of the rotor of the double-row bearing of the utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of main fulcrum structure of the rotor of double-row bearing, is arranged between axis 4 and bearing block 5, including two
Bearing 3, central oil pipe 2 and clearance adjuster 1.Bearing 3 selects ball bearing, and two bearings 3 and clearance adjuster 1 are sleeved on axis
Between 4 and bearing block 5, wherein clearance adjuster 1 is between two bearings 3, to adjust 3 Internal and external cycle axial position of two bearings,
The clearance adjuster 1 selection is set as annular construction member, and its inside and outside two circle is contradicted phase with two circles inside and outside two bearings 3 respectively
It connects.Central oil pipe 2 sets through bearing block and is inserted into clearance adjuster 1, and the end set for being inserted into 1 one end of clearance adjuster has
For lubricating the oil outlet of two bearings 3, and select oil outlet respectively setting spout at one towards two bearings 3.
Two 3 Internal and external cycle axial positions of bearing are adjusted by clearance adjuster 1 during assembling, ensure that two bearings 3 are respectively interior
Outer ring relative position is identical, that is, ensures two bearings 3 carrying and equal separate loading simultaneously.Central oil pipe 2 is located in two bearings 3
Between, both sides oil outlet lubricates two side bearings 3 simultaneously.Two 3 spacing of bearing are small, can for the larger rotor of length, span
A single fulcrum is considered, since two bearings 3 share load simultaneously, it is possible to increase more than 50% fulcrum bearing capacity, and then
It can preferably ensure rotor high-speed cruising safety and service life.
The above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, in the technical scope that any one skilled in the art discloses in the utility model, the change that can readily occur in
Change or replace, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with described
Subject to scope of the claims.
