Abstract
The invention supplies a water-cooling three-phase asynchronous high speed electric machine, relates to the improvement of the electric machine plate wall internal hydrocoel and the improvement of the bearing cooling manner. The water-cooling three-phase asynchronous high speed electric machine, based on the existing three-phase asynchronous electric machine structure, the cooling hydrocoel of bedplate is the gyroidal channel, the cooling water enters from the infall in the middle of bedplate, through the two way gyroidal channel outflow from the two terminal of the end piece outlet, the cooling water enter the end cap through the bedplate, formed the wate channel out of the end cap bearing room. The advantages of the invention lie in: 1.the cooling water enter from the middle of the bedplate, two terminal waterexit, avoided the condition that the iron core one end cooling but the other end hot, at the same time, fully cold heat change, the volume of the electric motor becomes smaller. 2. Forms the water channel outside of the end cap bearing room solved the high speed electric machine bearing heat question. 3. Water leak-proof quality between bedplate and the end cover is outstanding. 4. The high speed electric machine cast-aluminium rotor used the endring stainless steel guard ring structure, has solved the cast-aluminium rotor high-speed operation structural strength problem.
Description
Affiliated field
Water-cooling three-phase asynchronous high-speed motor of the present invention relates to the improvement of water cavity in the motor cabinet wall and the improvement of the bearing type of cooling.
Background technology
The mechanical test that is used for automobile engine and rotational structure.The requirement motor volume is little, speed is high, response is fast, moment of inertia is little, as adopts the conventional type of cooling not reach the requirement of load.The ball bearing of the general type of cooling also can't reach this rotating speed.Water-cooled machine generally adopts in the support wall water cavity is set, the water inlet lower end water outlet of support upper end.This water-cooling pattern often forms the dead band and water cavity can only be set in support in support.
Summary of the invention
The objective of the invention is to: provide a kind of water cooling sufficient water-cooling three-phase asynchronous high-speed motor.
The object of the invention can be achieved through the following technical solutions: on existing threephase asynchronous machine architecture basics, cooling water cavity in its support is spiral water channel, cooling water enters from the water inlet in the middle of the support, flow out from the delivery port of the end cap portions at two ends respectively through two road spirality channels, cooling water channel enters end cap through support, at the outdoor formation water channel of end cap bearing, because of cooling off fully, improved the heat exchanger effectiveness of motor, simultaneously, bearing is cooled off, solved the problem of high-speed electric expreess locomotive bearing heating.
For ensureing the water channel sealing, on the such scheme basis, the watertight construction of O RunddichtringO is adopted in the junction of two water channels between support and end cap.
Because of cooling effectiveness improves motor volume is dwindled, though created prerequisite for improving motor speed, still there is strength problem in the casting aluminium rotor end ring of high-speed electric expreess locomotive, and high-speed electric expreess locomotive cast-aluminum rotor of the present invention adopts end ring stainless steel retaining ring structure.
Superiority of the present invention is: (one) changes the cooling water cavity of support into spiral cooling water channel, and is provided with the water channel of two directions, brings out water from the middle water inlet of support, two, to avoid the situation of the cold end heat of an end unshakable in one's determination.Adopt spirality channel that the flow velocity of water in motor slowed down, cold and hot exchange is abundant, makes the volume of motor littler.(2) cooling water channel enters end cap through support, at the outdoor formation water channel of end cap bearing, bearing is cooled off, and has solved the problem of high-speed electric expreess locomotive bearing heating.(3) watertight construction between support and the end cap, an O RunddichtringO, easy to do head it off are adopted in two water channel junctions.(4) the high-speed electric expreess locomotive cast-aluminum rotor adopts end ring stainless steel retaining ring structure to solve the cast-aluminum rotor structural strength problem that runs up.

Embodiment:
Partly cut open shown in schematic diagram and Fig. 2 structure side view of the present invention as Fig. 1 structure of the present invention, on existing threephase asynchronous machine architecture basics, cooling water cavity in its support 5 is spiral water channel 71, cooling water enters from the water inlet 51 in the middle of the support 5, through two road spirality channels from respectively from the end cap 31 at two ends, delivery port 311 on 32,321 flow out, cooling water channel enters end cap through support 5, at end cap 31,32 bearing chambers form water channel 72 outward, 73, because of cooling off fully, improved the heat exchanger effectiveness of motor, simultaneously, to bearing 21,22 cool off, and have solved the problem of high-speed electric expreess locomotive bearing heating.
For ensureing the water channel sealing, on the such scheme basis, the watertight construction of O RunddichtringO 6, easy to do solution are adopted in the junction of two water channels between support water channel 71 and end cap water channel 72,73.
Because of cooling effectiveness improves, though created prerequisite, new demand has been proposed high speed rotor of motor 9 intensity for improving motor speed, high-speed electric expreess locomotive cast-aluminum rotor of the present invention adopts end ring stainless steel retaining ring 41,42 structures.
Application examples
Utilize YGS200M1-4 100kW 4 utmost point frequency control motors of this mechanical development, the motor rated speed is 4500r/min, and maximum speed reaches 10000r/min.The water cooling mode of the spiral channel that adopts, design water flow 1m
3/ h, hydraulic pressure≤1.5Mpa, the Inlet and outlet water temperature difference are 6 ℃.The bearing that motor is selected for use is 6212 C4, can only reach 5600r/min at the condition limit inferior rotating speed of grease lubrication and therefore adopt water-cooled method outside the bearing chamber, has well solved this problem.Water enters water channel and enters end cap from the outflow of support end face from the support top, at last from end cap bottom water outlet.Casting aluminium rotor end ring adopts the stainless steel retaining ring, and structure is seen accompanying drawing, and motor has satisfied load fully through test to be wanted.Motor is under fully loaded full gear ruuning situation, and the winding temperature rise is 64K, and bearing temperature is 65 ℃, and the postrun insulation resistance of motor reaches 200M Ω, illustrates that hermetically-sealed construction is good.
