Description
Technical field
This utility model belongs to motor component field, is specifically related to air compressor motor special bearing and rotates and protection device.
Background technology
Air compressor motor is a kind of to apply quite varied motor on air compressor machine, and this motor has the feature of two aspects: the most this motor is typically all encapsulated in inside a casing, in indoor use together with air compressor machine.An air inlet is had before and after above casing, one air outlet, to increase the impact on motor such as degree of protection and minimizing rainwater, the noise sent when also reducing air compressor machine and motor operation impact to external world, the present that old-fashioned air compressor machine being directly installed on indoor has been eliminated.The most this motor is generally bipolar machine, so that motor increases air supply under the conditions of Same Efficieney.But this installing and using mode and general motor is different, be mainly manifested in owing to motor radiating condition is poor, cause temperature rise the highest, thus make motor temperature rise cause bearing temperature also to remain high, because being bipolar machine, motor speed height causes bearing easily to damage.
Summary reason, inventor devises the bearing tumbler coordinating air compressor machine motor special.
Summary of the invention
Technical problem to be solved in the utility model is to provide air compressor motor special bearing and rotates and protection device, it is possible to solve the problem that air compressor machine motor special causes bearing rapid wear because of temperature rise.
For solving above-mentioned technical problem; the technical solution of the utility model is: the air compressor motor special bearing described in utility model rotates and protection device; it is characterized in that: include bearing rotary outer shroud and bearing rotary internal ring; the resilient support arms of more than three is set between bearing rotary outer shroud and bearing rotary internal ring; one end of resilient support arms is welded on bearing inner ring, and the other end of resilient support arms is welded on bearing rotary outer shroud；Bearing rotary outer shroud is fixed on motor bearing end cover；Bearing rotary internal ring includes four circular arcs, is connected by block rubber between each two circular arc, offers bearing roller groove, arrange bearing roller in bearing roller groove on the inner side of bearing rotary internal ring；Bearing set in bearing rotary internal ring；Bearing roller contacts with bearing.
Preferably, resilient support arms arranging auxiliary pressing spring, one end of auxiliary pressing spring connects resilient support arms, and the other end of auxiliary pressing spring connects bearing rotary outer shroud.
Compared with prior art, the beneficial effects of the utility model are:
1, in order to ensure the stability that motor runs, inventor is provided with bearing rotary ring in motor bearing end cover, bearing rotary ring is divided into outer shroud and internal ring, resilient support arms is set between internal ring and outer shroud, in order to solve because motor speed is high, temperature rise is fast, bearing stress problem in the axial direction when expanding with heat and contract with cold.Being flexible coupling by block rubber, the diameter that can make bearing rotary internal ring changes with the diameter of bearing and is finely adjusted, this design is in the case of keeping high rotating speed constant, bearing around leaves expansion space after being heated, no matter can consolidate at any temperature conditions lower bearing and install and use, failure ratio is greatly lowered.
2, this utility model adds bearing wheel rolling in the design, place it in the both sides that block rubber is flexible coupling, avoiding owing to bearing rotary internal ring is divided into four circular arcs, the bearing roller that may bring in the seam place of each two circular arc rotates and has some setbacks, and causes mechanical damage problem.This is novel in design practical, and cost of manufacture is low, and maintenance cost is little.
3, this device arranges between bearing rotary internal ring and bearing rotary outer shroud resilient support arms and auxiliary pressing spring, what this design can continue when motor temperature rise provides support force to bearing rotary internal ring, because after bearing height rotating speed expanded by heating, bearing rotary internal ring expands therewith, but bearing continues in high speed rotating, in order to ensure the smoothness of bearing high speed rotating, need to make whole expansion process be constantly in the control of peripheral pressure, so adding resilient support arms and auxiliary pressing spring coordinated, realize the expansion ratio of bearing rotary internal ring is carried out spacing control.The design advantage of this device ensures the normal operation of equipment while being guarantee equipment temperature rise speed.

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, air compressor motor special bearing rotates and protection device, including bearing rotary outer shroud 1 and bearing rotary internal ring 3, thus the bearing thermal expansion that motor bearings high speed rotating brings is offseted than on bearing rotary internal ring 3.The resilient support arms 2 of more than three is set between bearing rotary outer shroud 1 and bearing rotary internal ring 3, one end of resilient support arms 2 is welded on bearing inner ring, the other end of resilient support arms 2 is welded on bearing rotary outer shroud 1, bearing rotary internal ring 3 is kept to be in all the time under suitable force-bearing situation by resilient support arms 2, properly functioning to ensure that equipment still ensures after rapid warm raising.
Auxiliary pressing spring 4 is set in resilient support arms 2, one end of auxiliary pressing spring 4 connects resilient support arms 2, the other end of auxiliary pressing spring 4 connects bearing rotary outer shroud 1, auxiliary pressing spring 4 is that the pressure to resilient support arms 2 supplements, because resilient support arms 2 needs to there is certain brachium, in the case of temperature rise is too high, support effect is unstable, so falling into auxiliary support arm, when device temperature peaks value, resilient support arms 2 is not enough to spring bearing and rotates internal ring 3, now auxiliary pressing spring 4 can rely on bearing rotary outer shroud 1 to be basic point, aux. pressure is provided to give resilient support arms 2, make it act on still to exist.
Bearing rotary outer shroud 1 is fixed on motor bearing end cover, this device entirety is inlaid on motor bearing end cover, bearing set in bearing rotary internal ring 3.Bearing rotary internal ring 3 is divided into four circular arcs, it is connected by block rubber 7 between each two circular arc, it is easy to when bearing 5 thermal expansion, bearing rotary internal ring 3 can be with the change of bearing 5 diameter, it is finely adjusted, make it adapt to the high-speed rotation of bearing 5 all the time, reduce bearing 5 resistance when expanding with heat and contract with cold in the axial direction, reduce bearing 5 simultaneously and continue temperature rise.Bearing roller groove is offered in the both sides of block rubber 7, bearing roller 6 is set in bearing roller groove, bearing roller 6 is corresponding with bearing, avoid owing to bearing rotary internal ring 3 is divided into four circular arcs, the bearing roller 6 that may bring in the seam place of each two circular arc rotates and has some setbacks, and causes mechanical damage problem.
The above, it it is only preferred embodiment of the present utility model, being not the restriction that this utility model is made other form, any those skilled in the art are combined possibly also with the technology contents of the disclosure above, change or retrofit and are Equivalent embodiments of the present utility model.But every without departing from technical solutions of the utility model content, any simple modification, equivalent variations and remodeling above example made according to technical spirit of the present utility model, still fall within the protection domain of technical solutions of the utility model.
