Description
Technical field
The utility model belongs to motor field, specially a kind of machine shaft.
Background technology
With the development of science and technology, motor needs to be applied to various particular surroundings, wherein hot environment is to electric machine operation state
Influence it is maximum, to ensure the steady operation of motor, the temperature of motor body should be at 300 DEG C or less.When machine shaft exports
When the operating temperature at end is higher than 300 DEG C, high temperature will be conducted by machine shaft to motor, and influence directly connects with machine shaft
The cooperation of the connectors such as the bearing connect, and harmful effect is caused to each component in motor.In the prior art generally use water cooling or
It is air-cooled that cooling and heat dissipation is carried out to motor, but this heat dissipation effect is limited, when the operating temperature of machine shaft output end is in 700
DEG C~1500 DEG C when, the above method can no longer meet the cooling requirement of motor.The producer having currently on the market is using heatproof gold
Belong to alloy and makes machine shaft, it is with high costs although improving the heat insulation of machine shaft in this way, it can not produce in batches
It uses.
Utility model content
The purpose of this utility model is to provide a kind of machine shafts, can promote the stability of motor work.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of machine shaft, including it is mounted on motor
Interior interior shaft, the interior outwardly extending axle stretch end of shaft are connected by transition axis with outer shaft, and transition axis is using zirconium oxide, carbonization
Silicon or silica are made.
Compared with prior art, there are following technique effects for the utility model：Transition axis can completely cut off outer shaft and interior turn
Heat transfer between axis to the failure for avoiding the connectors such as interior shaft and bearing caused by high temperature from coordinating, and then is effectively promoted
The Stability and dependability of motor work.

In figure：Shaft in 11., 12. outer shafts, 13. transition axises, 20. ring flanges, 21. connecting holes, 22. bolts.
Specific implementation mode
Below in conjunction with the accompanying drawings, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
It describes in detail bright.
A kind of machine shaft, includes the interior shaft 11 in motor A, and 11 outwardly extending axle stretch end of interior shaft passes through
Transition axis 13 is connected with outer shaft 12, and transition axis 13 is made of heat-barrier material.Transition axis 13 can completely cut off outer shaft 12 in this way
With the heat transfer between interior shaft 11.Specifically as shown in Figure 1, stretching into operating temperature in outer shaft 12 is in 700 DEG C~1500 DEG C
Hot operation region B in when, due to the setting of transition axis 13 so that high temperature will not pass through the conduction of outer shaft 12 to interior shaft
11, to the failure for effectively avoiding the connectors such as interior shaft 11 and bearing caused by high temperature from coordinating, and then greatly promote motor A works
The Stability and dependability of work.
Preferably, the transition axis 13 is made of zirconium oxide, silicon carbide or silica.Zirconium oxide and silicon carbide etc.
Material has the characteristics that high intensity, high-melting-point, pyroconductivity are low, can work long hours in the environment of 1500 DEG C, both can guarantee
The transmission of torque, and it is avoided that the normal operation of high temperature conduction effects motor.
Preferably, as shown in Fig. 2, the inside and outside shaft 11,12 and transition axis 13 are integral type sinter molding shaft part.
When sintering as shown in figure 3, mold both ends fill metal powder, sintering aftershaping be inside and outside shaft 11,12, middle part fill every
Hot material powder, sintering aftershaping are transition axis 13.
Preferably, as shown in figure 4, the outer diameter of the transition axis 13 is equal with inside and outside shaft 11,12, the two of transition axis 13
End respectively with inside and outside shaft 11,12 laser sintered connections.It can be directly processed, be used using common electric machine shaft in this way
Laser sintering process realizes the heat-barrier material of high intensity and being fixedly connected for metal machine shaft, easy making process and of low cost.
Preferably, the inside and outside shaft 11,12 is respectively equipped with ring flange 20, ring flange 20 adjacent to the end of transition axis 13
Disk edge on ring its be axially arranged with the connecting hole 21 for 22 company of wearing of bolt, transition axis 13 is located between two ring flanges 20 and passes through
Bolt 22 is fixedly connected.Further, the outer diameter of the transition axis 13 is greater than or equal to inside and outside shaft 11,12, to ensure transition
The heat insulation of axis 13.As shown in Figure 5,6, inside, the mutually adjacent end set ring flange 20 of outer shaft 11,12 was convenient for
Cross the reliable installation of axis 13.Bolt 22 can also be made of heat-barrier material, further avoid heat through bolt 22 realize from it is interior,
Conduction between outer shaft 11,12.
