Description
Technical field
The utility model relates to field of machining and machinebuilding technology, are applied in speed reducer mechanical equipment, relate in particular to one
Variable-speed motor of the kind with the cold outer circulation of oil.
Background technique
Speed reducer is the equipment for promoting torque for reducing revolving speed.It is the important component of dynamical system, is that key is set
It is standby, it is occupied an important position in entire power device.Speed reducer itself is the equipment for having rotary part, rotary part
Even running for rotation axis, rotation axis is particularly significant for speed reducer, and gear is equipped in shaft, and different gears is mounted on
In different shafts, intermeshing forms gear mesh, has certain speed ratio, increases torque to have the function that slow down.
While engagement, a large amount of heat can be generated, if the temperature of meshing gear pair cannot be reduced in time, will lead to gear shifting quadrant texturing,
Cause vibration to increase, and then deteriorates final generation tooth face agglutination even heel fracture.
Utility model content
The purpose of this utility model is to provide one kind to be not necessarily to additional other equipment, and structure simply has the cold outer circulation of oil
Variable-speed motor.
In order to solve the above technical problems, the purpose of this utility model is achieved through the following technical solutions:
Variable-speed motor with the cold outer circulation of oil, by reducer shell, lubricating oil, air cooler, cooling water heat exchanger tube and circulation
Pump assembly composition；
The inside lower half portion of reducer shell is arranged in the lubricating oil, and the air cooler is fixedly mounted on the decelerator body
The outside of body is fixedly mounted on the same pedestal with reducer shell, and circulation water inlet is provided on the air cooler and is followed
Ring water out, the outlet of the circulation water inlet connection circulation pump assembly, the circulating water outlet connect cooling water heat exchanger tube
The outlet of entrance, the cooling water heat exchanger tube is connected with circulation pump assembly.
Cooling water exchanges heat after air cooler with air, and temperature decline, the cooling water by cooling passes through recirculated water
Outlet enters cooling water heat exchanger tube, exchanges heat with lubricating oil, lubricating oil is cooled, the cooling water after heat exchange enters circulation
Enter recirculated water entrance after pump assembly, carries out circulating cooling.
The utility model has the beneficial effects that:
Variable-speed motor described in the utility model with the cold outer circulation of oil is not necessarily to additional other equipment, and lubricating oil setting is becoming
Fast machine enclosure interior, lower part of the housing have cooling water heat exchanger tube, and cooling water is recirculated cooling water, and circulation is equipped with outside variable-speed motor
Water-air cooling device after recirculated water is cooled in air cooler, absorbs the heat of lubricating oil, is sufficiently changed in lubricating oil bath of entering
Heat.For entire variable-speed motor device on a pedestal, overall skid-mounted is compact-sized, powerful.This change with the cold outer circulation of oil
Fast machine structure is simple, easy to use, easy for installation, safe and reliable and easy to maintain, had not only improved production efficiency but also to subtract
The service life of fast machine effectively extends, and large batch of put goods on the market will generate positive social benefit and significant economic effect
Benefit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the variable-speed motor with the cold outer circulation of oil；
Wherein, 1- reducer shell；2- lubricating oil；3- air cooler；31- recycles water inlet；32- circulating water outlet；4- is cold
But water heat exchanger tube；5- recycles pump assembly.
Specific embodiment

Under the premise of implemented, give detailed embodiment, but the protection scope of the utility model is not limited to following embodiments.
As shown in Figure 1, the variable-speed motor with the cold outer circulation of oil, by reducer shell 1, lubricating oil 2, air cooler 3, cooling water
Heat exchanger tube 4 and circulation pump assembly 5 form；
The inside lower half portion of reducer shell 1 is arranged in the lubricating oil 2, and the air cooler 3 is fixedly mounted on deceleration
The outside of casing body 1 is fixedly mounted on the same pedestal with reducer shell 1, is provided with recirculated water on the air cooler 3 and is entered
Mouth 31 and circulating water outlet 32, the outlet of the circulation water inlet 31 connection circulation pump assembly 5, the circulating water outlet 32 connect
The outlet of the entrance of cooling water heat exchanger tube 4, the cooling water heat exchanger tube 4 is connected with circulation pump assembly 5.
Cooling water exchanges heat after air cooler 3 with air, and temperature decline, the cooling water by cooling is by circulation
Water out 32 enters cooling water heat exchanger tube 4, exchanges heat with lubricating oil 2, and lubricating oil 2 is cooled, the cooling water after heat exchange
Enter recirculated water entrance 31 after into circulation pump assembly 5, carries out circulating cooling.
The preferable specific embodiment of the above, only the utility model, these specific embodiments are all based on this
Different implementations under utility model general idea, and the protection scope of the utility model is not limited thereto, it is any ripe
Know those skilled in the art within the technical scope disclosed by the utility model, any changes or substitutions that can be easily thought of, all
It should cover and be within the protection scope of the utility model.
