Abstract
The utility model particularly relates to a water cooling motor housing with a leakage prevention structure, and the problems of occasional generation of the phenomenon of water leakage of a weld joint and high reworking rate are solved during the production process of the conventional water cooling motor housing. The water cooling motor housing with a leakage prevention structure comprises a flange, an inner cylinder, and an outer cylinder; ribs are arranged between the inner cylinder and the outer cylinder; an end part of the inner cylinder is clamped into a groove opened in a corner part at an inner side of the flange; the inner cylinder is fixed with the flange in a welding manner; a ring rib contacted with an end face at the furthest outer side of the flange is welded on an outer side face of the inner cylinder; and the furthest outer side of the flange, one side end face of the outer cylinder, and an outer side end face of the ring rib are fixed together in a welding manner. According to the utility model, a cooling water path is staggered with a weld joint 2; the reworking rate of the water cooling motor housing is reduced by over a half; operation and inspection during welding for a second time are more easy; the structure is novel; the manufacturing is simple; and production efficiency is high.
Description
Technical field
The utility model relates to the water-cooled machine shell, is specially a kind of water-cooled machine shell with anti-leakage structure.
Background technology
The electric drive system coal-winning machine is reduced volume, increases power with the technology trends of motor, promptly improves power density.Along with the continuous lifting of coal-winning machine design of electrical motor power density, the unit volume loss that produces when making the motor operation constantly increases, and causes that motor each several part temperature raises.Therefore improve cooling system, reduce electric machine temperature rise and become one of coal-winning machine motor technology main direction of studying.Because the special construction of electric drive system coal-winning machine and motor itself improve the requirement of power density, it is increasingly extensive to make the shell Water Cooling Technology in electric drive system coal-winning machine motor, use.Therefore, how to improve the heat-sinking capability of motor water cooling shell, the production cost of reduction water cooled housing, become one of subject matter of coal-winning machine motor technology development.Traditional water cool electric machine shell comprises flange (1), is welded with urceolus (4) and inner core (5) on the flange (1) respectively, is provided with rib (6) between urceolus (4) and the inner core (5), and rib (6) and urceolus (4) and inner core (5) form cooling water channel.But urceolus (4) is the closed weld seam in water route with weld seam, the inner core (5) of flange (1) with the weld seam of flange (1), and promptly the weld seam of seepage might appear in cooling water.This weldquality requires very high, careless slightlyly just might cause seepage.In a single day particularly the weld seam of inner core (5) and flange (1) is positioned at the motor inner core, is difficult for during detection observing, and seepage takes place in the future, water will directly get into motor internal, influences the motor safety operation.Therefore there is very big potential safety hazard.Simultaneously; Inner core (5), urceolus (4), flange (1) are the preceding workpiece of weldering, and machining accuracy is not high, and assembling also might be not in place; Cause between assembling rear flange (1) and the rib (6) and have slit (9); Influence cooling water channel (6) circulation, make the cooling water short circuit, reduce cooling effect.
Summary of the invention
The utility model is in order to solve existing water-cooled machine shell in process of production, and the problem that the weld seam drainage happens occasionally, rework rate is very high provides a kind of water-cooled machine shell with anti-leakage structure.
The utility model is to adopt following technical scheme to realize: the water-cooled machine shell of band anti-leakage structure; Comprise flange, inner core, urceolus; Be provided with rib between inner core and the urceolus, the inner core end snaps in the groove that the inboard bight of flange has, and inner core is fixed with the flange welding; Be welded with the ring muscle that contacts with flange outermost end face on the inner core lateral surface in addition, the common welding of outside end face of a side end face of flange outermost end face, urceolus, ring muscle is fixing.The fixing weld seam II that forms of inner core and flange welding, the fixing weld seam I that forms of the common welding of outside end face of a side end face of flange outermost end face, urceolus, ring muscle.Inner core, urceolus, flange constitute the water-cooled machine shell.During manufacturing, will encircle muscle earlier and be welded on the inner core, then with inner core, urceolus hot jacket, assembly flange behind the hot jacket.Because cooling water channel and weld seam II stagger, having only the weld seam I is the closed weld seam in water route, and the weld seam II no longer is the closed weld seam in water route.The weld seam I is positioned at the water-cooled machine outer surface of outer cover, is easy to during detection observe, and seepage occurs and is easy to repair.
The beneficial effect of the utility model is following: utilize special flange and the structure of setting up the ring muscle, realized that cooling water channel and weld seam II stagger, reach water-cooled machine shell rework rate and reduce by more than 50, and return more easy to operate and inspection when welding.The utility model novel structure is made simply, and production efficiency is high.
Description of drawings
Fig. 1 is the leakage preventing structure sketch map of existing water-cooled machine shell;
Fig. 2 is the structural representation of the utility model.
Among the figure: the 1-flange, 2-weld seam I, 3-encircles muscle, 4-urceolus, 5-inner core, 6-rib, 7-weld seam III, 8-weld seam II, 9-slit.
Embodiment
The water-cooled machine shell of band anti-leakage structure; Comprise flange 1, inner core 5, urceolus 4; Be provided with rib 6 between inner core 5 and the urceolus 4, inner core 5 ends snap in the groove that flange 1 inboard bight has, and inner core 5 is fixing with flange 1 welding; Be welded with the ring muscle 3 that contacts with flange 1 outermost end face on inner core 5 lateral surfaces in addition, the common welding of outside end face of a side end face of flange 1 outermost end face, urceolus 4, ring muscle 3 is fixing.
In the practical implementation process, in 400kW coal-winning machine water-cooled machine shell, increase the ring muscle, the ring muscle forms for the weldering of 10x10 square steel volume, volume postwelding ring muscle internal diameter φ 612.To encircle muscle and be welded in inner core requirement position, then with urceolus, flange assembling and welding.
