Abstract
The present invention relates to a high-speed beairng, in particular, it is a spinning rotor for mounting break spinning machine. It includes a jshaft and a cylindrical bushing. Said shaft and bushing are equipped with mutually-separated steel-made circular guide tracks, in every guide track a train of rolling contact bodies guided by means of retaining frame is received, and in every train of rolling contact bodies at least one rolling contact body is made up by using silicon nitride Si3N4, and other rolling bodies are made of steel, and the number of Si3N4 rolling contact bodies is less than that of steel-made rolling contact bodies.
Description
The present invention relates to a kind of high-speed bearing, be particularly useful for installing the spinning rotor of free-end spinning machine, this high-speed bearing comprises an axle and a cylindrical bush, this axle and lining all are provided with steel circular track spaced apart from each other, contain the rolling contact of row by the retainer guiding in each track.
As everyone knows, high-speed bearing, be particularly useful for installing the main shaft of centrifuge, comprise a steel axle, has a pair of circular track spaced apart from each other on it, with a cylindrical steel lining, this lining also has a pair of circular track spaced apart from each other, all contains the rolling contact of row by the retainer guiding in each track.
The shortcoming of this structure is, when high speed since heavier steel rolling contact with too much loading on circular track, so greatly reduce the working life of bearing.
In order to overcome this shortcoming, a kind of solution of relevant high-speed bearing has been proposed among the patent CZ281421, be particularly useful for centrifuge, this high-speed bearing comprises a steel axle, it is provided with an a pair of steel circular track spaced apart from each other and a cylindrical steel lining, and this lining also has a pair of steel circular track spaced apart from each other, all accommodate the rolling contact by the retainer guiding in each track, this rolling contact is to be made by special pottery.
This structure corresponding advantages is, can obtain high working life of when high speed, installing, yet, owing to need a large amount of very uses of expensive high technology ceramics rolling contact, so this advantage is to be cost with the relevant high cost of the manufacturing of this sleeve.
The object of the present invention is to provide a kind of high-speed bearing, be particularly useful for installing the spinning rotor of free-end spinning machine, this bearing has low cost and enough working life.
Realized purpose of the present invention on high-speed bearing, in particular for the spinning rotor of free-end spinning machine is installed, this principle is that in the rolling contact of each row, at least one rolling contact is by silicon nitride Si
3N
4Make, simultaneously remaining rolling contact is formed from steel, in each row by silicon nitride Si
3N
4The number of the rolling contact of making is less than the number of the rolling contact that is formed from steel.
This structure of high-speed bearing is particularly useful for installing the spinning rotor of free-end spinning machine, allows to reduce the manufacturing expense of bearing, when remaining on high speed simultaneously, and enough bearing working life.
Accompanying drawing illustrates high-speed bearing of the present invention briefly, is used to install a longitudinal cross-section of the spinning rotor of free-end spinning machine.
High-speed bearing, be particularly useful for installing the spinning rotor of free-end spinning machine, comprise an axle 1 and a cylindrical bush 2, this axle and lining all are provided with a pair of steel circular track spaced apart from each other, are all holding the rolling contact 3 of row by retainer 4 guiding in each track.Each end at sleeve 2 all is equipped with a Sealing 5, is provided with a snap ring 6 on the outer surface of sleeve.
In the rolling contact 3 of each row, the part of rolling contact is formed from steel, and another part of rolling contact 3 is by silicon nitride Si in each row
3N
4Make.In each row, by silicon nitride Si
3N
4The number of the rolling contact of making 3 is less than the number of the rolling contact 3 that is formed from steel.In other words, in each row rolling contact 3, by silicon nitride Si
3N
4The ratio of the number of the rolling contact of making 3 and the number of the rolling contact 3 that is formed from steel is less than 1.This just means that in the rolling contact 3 of each row, at least one rolling contact is by silicon nitride Si
3N
4Make, and at least one rolling contact is formed from steel.
From rotating the power effect angle of material, be favourable if the rolling contact 3 of every kind of material is evenly distributed on the circumference of circular track of each row rolling contact 3.
