Abstract
A kind of electric machine support bearing chamber heating frock, for operation before rolling bearing is loaded electric machine support bearing chamber, comprises heater support, positioning seat, bearing chamber heating head, heat-generating pipe and temperature controller; The positioning seat being positioned at described heater support is the cylindricality round platform can placing motor machine support, the bearing chamber heating head of the bossed cylindricality in middle part on the positioning seat top of described cylindricality round platform, described heat-generating pipe and temperature controller are arranged in the inner chamber of this positioning seat and bearing chamber heating head, and heat-generating pipe is electrically coupled to temperature controller; The heating end of described heat-generating pipe is fixed in bearing chamber heating head; When described electric machine support is positioned over positioning seat, the upper bearing chamber heating head of positioning seat inserts in the bearing chamber of described electric machine support just.The beneficial effects of the utility model be can better ensure rolling bearing be positioned over the bearing chamber of electric machine support after concentricity, avoid high strength pressure to the destruction of rolling bearing.
Description
Technical field
The utility model relates to motor, is particularly exclusively used in manufacture, assembling, safeguards or the method and apparatus of repairing motor, particularly relate to the heating frock of the electric machine support bearing chamber for mounted motor rolling bearing.
Background technology
The rolling bearing of motor is arranged in electric machine support bearing chamber with requiring close-fitting, and prior art installs rolling bearing, is to adopt frock to apply pressure to rolling bearing to make it directly be pressed into electric machine support bearing chamber.This mounting means, is easy to cause rolling bearing steel ring to be out of shape when rolling bearing room tension, thus destroys bearing, and the frock that rolling bearing is pressed into directly is difficult to the concentricity ensureing rolling bearing and axle by this employing.
Utility model content
The technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part to propose electric machine support bearing chamber heating frock, solves existing technology direct-type and to install in bearing frock installation process fragile axle and easily cause the problems such as rolling bearing steel ring distortion.
The utility model is solve the problems of the technologies described above the technical scheme proposed to be, a kind of electric machine support bearing chamber heating frock, for operation before rolling bearing is loaded electric machine support bearing chamber, comprise heater support, positioning seat, bearing chamber heating head, heat-generating pipe and temperature controller; The positioning seat being positioned at described heater support is the cylindricality round platform can placing motor machine support, the bearing chamber heating head of the bossed cylindricality in middle part on the positioning seat top of described cylindricality round platform, described heat-generating pipe and temperature controller are arranged in the inner chamber of this positioning seat and bearing chamber heating head, and heat-generating pipe is electrically connected to temperature controller; The heating end of described heat-generating pipe is fixed in bearing chamber heating head; When described electric machine support is positioned over positioning seat, the bearing chamber heating head above positioning seat inserts in the bearing chamber of described electric machine support just.
Bearing chamber heating head external diameter and the described electric machine support bearing chamber internal diameter of described cylindricality are suitable, and the outer wall of bearing chamber heating head is contacted with the internal face of electric machine support bearing chamber.
The beneficial effects of the utility model are: can better ensure rolling bearing be positioned over the bearing chamber of electric machine support after concentricity, avoid high strength pressure to the destruction of rolling bearing.
Accompanying drawing explanation
Fig. 1 is the orthographic projection schematic front view of the electric machine support bearing chamber heating frock in preferably implementing of the utility model electric machine support bearing chamber heating frock;
Fig. 2 is the axonometric projection schematic diagram of electric machine support bearing chamber heating frock in described preferred embodiment.
Embodiment
below, shownschematically preferred embodiment sets forth the utility model further by reference to the accompanying drawings.
See Fig. 1 to Fig. 2, the preferred embodiment of the utility model is, design, produce a kind of electric machine support bearing chamber heating frock, for operation before rolling bearing is loaded electric machine support bearing chamber, comprise heater support 5, positioning seat 2, bearing chamber heating head 1, heat-generating pipe 3 and temperature controller 4; The positioning seat 2 be positioned on described heater support is the cylindricality round platform can placing motor machine support, the bearing chamber heating head 1 of the bossed cylindricality in middle part on positioning seat 2 top of described cylindricality round platform, described heat-generating pipe 3 and temperature controller 4 are arranged in the inner chamber of this positioning seat 2 and bearing chamber heating head 1, and heat-generating pipe 3 is electrically connected to temperature controller 4; The heating end of described heat-generating pipe 1 is fixed in bearing chamber heating head 1; When described electric machine support is positioned over positioning seat 2, the upper bearing chamber heating head 1 of positioning seat 2 inserts in the bearing chamber of described electric machine support just.
Bearing chamber heating head 1 external diameter and the described electric machine support bearing chamber internal diameter of described cylindricality are suitable, and the outer wall of bearing chamber heating head 1 is contacted with the internal face of electric machine support bearing chamber.
Before rolling bearing loads electric machine support bearing chamber, the electric machine support bearing chamber heater that electric machine support is positioned in the present embodiment is loaded onto, bearing chamber is heated, when bearing chamber adstante febre, electric machine support expanded by heating, bearing chamber endoporus becomes large, then electric machine support is taken out, again rolling bearing is put in bearing chamber, when after electric machine support cooling, because electric machine support cooling rear axle bearing bore diminishes, thus tightly encase rolling bearing, often the support of motor is aluminium alloy or kirsite, and these material hardnesses are all little than the steel ring of rolling bearing, when after cooling, endoporus shrinks, impact can not be had to rolling bearing, thus reach the fastening effect of rolling bearing.The internal diameter of this heating frock bearing chamber heating head 1 external diameter and described electric machine support bearing chamber is suitable, the outer wall of bearing chamber heating head 1 is contacted with the internal face of electric machine support bearing chamber, bearing chamber heating head 1 is just inserted in electric machine support bearing chamber, so just, carry out heating electric machine support bearing chamber with heat trnasfer, because the temperature around bearing chamber heating head 1 is the same, the thermal expansion of electric machine support bearing chamber is also the same, the concentricity of so good guarantee electric machine support bearing chamber.So just can better ensure that rolling bearing is positioned over the concentricity of electric machine support bearing chamber, avoid high strength pressure to the destruction of rolling bearing.
