Abstract
The invention relates to a structure of a circulating water cooled shell of a motor. The structure comprises a shell inner ring and a shell outer ring. The structure is characterized in that the shell inner ring formed in a way that a steel plate is rolled to be in a round shape is arranged in the shell outer ring, fixed connecting rings are welded on both ends of the shell, circulating water flow channel spacing rib plates are welded on the circumference of the shell inner ring to form a circulating water flow channel which is in a U shape, the cut steel plate side of the shell outer ring is rolled to be in a round shape and then is welded onto the inner ring, a water inlet and a water outlet are formed in one end of the shell outer ring, a motor outlet hole is formed in the other end of the shell outer ring, and the bottom of the motor outlet hole is positioned in the shell inner ring. The structure has the advantages of reasonable design, simplicity, compactness, low cost, convenience in processing and assembly, light product weight and small size, the thickness of the steel plate of the shell outer ring can be reduced, the anti-vibration requirement can be satisfied, and the motor can be effectively cooled.
Description
Technical field
The present invention relates to the technical field of motor case cooling, specifically a kind of structure of motor cycle water cooling casing.For the driving cutter motor of shielding tunnel excavator.
Background technology
The driving cutterhead motor of current domestic shielding tunnel excavator, the casing structure of its circulating water, includes inner ring, outer ring.The technique of present processing is: first by round for the Internal and external cycle roll of steel plate cut out, welding; and weld water channel gusset, then carry out the processing of matching ring size, then in order to protect built-in pipe to adopt hot-mounting process; Internal and external cycle is installed, fixes and welding, finally carry out welding and fine finishining.The shortcoming of this technique is: one is the increase in casing outer ring wall thickness, at least 8mm, and the use of material increases, and product weight is large, and overall dimension strengthens, and motor cost is increased, its complex structure, motor radiating efficiency is low; Two is that the precise requirements that casing outer ring needs is very high, otherwise is easily machined away commissure during casing fine finishining, thus causes revealing, and causes burn-down of electric motor, is easilier damaged by the cutterhead of shielding tunnel excavator, brings huge economic loss.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology, provide a kind of reasonable in design, structure is simple, compact, the convenient and structure of lower-cost motor cycle water cooling casing of process and assemble.
The technical solution adopted in the present invention is: a kind of structure of motor cycle water cooling casing, comprise casing inner ring, casing outer ring, it is characterized in that with the inside of the round-formed casing inner ring of roll of steel plate in casing outer ring, the two ends of casing are welded with and are fixedly connected with ring, circulating water passage interval gusset is welded on the circumferentially formation circulating water passage of casing inner ring, circulating water passage takes the shape of the letter U passage, casing outer ring cutting steel plate limit coiled round edge welds on inner ring, one end on casing outer ring is provided with water inlet and delivery port, the other end on casing outer ring is provided with motor outlet wire hole, the bottom in motor outlet wire hole is on casing inner ring.
The present invention is reasonable in design, and structure is simple, compact, and process and assemble is convenient, and casing outer ring steel plate thickness can be made to reduce, and its thickness is 3mm, and product weight is light, volume is little, and cost significantly reduces, and meets anti-vibration requirement, effectively realizes the cooling of motor.

Mark in figure: 1, be fixedly connected with ring, 2, casing inner ring, 3, casing outer ring, 4, motor outlet wire hole, 5, circulating water passage interval gusset, 6, water inlet, 7, delivery port.
Embodiment
By Fig. 1, 2, 3, 4 is known, a kind of structure of motor cycle water cooling casing, comprise casing inner ring 2, casing outer ring 3, first the casing inner ring 2 round-formed by the roll of steel plate cut out is welded, with the inside of the round-formed casing inner ring 2 of roll of steel plate in casing outer ring 3, the two ends of casing are welded with and are fixedly connected with ring 1, circulating water passage interval gusset 5 is welded on the circumferentially formation circulating water passage of casing inner ring 2, circulating water passage takes the shape of the letter U passage, casing outer ring 3 cuts, its one end is fixedly welded on casing inner ring 2, limit coiled round edge welds by hand, one end on casing outer ring 3 is provided with water inlet and delivery port, the other end on casing outer ring is provided with motor outlet wire hole, the bottom in motor outlet wire hole is on casing inner ring.
Process and assemble through the following steps:
1, be fixedly connected with ring 1 according to drawing requirement processing casing two ends, cut out inner ring roll of steel plate circle, form casing inner ring 2; Cut out casing outer ring 3 steel plate;
2, by drawing and development size figure, processing casing inner ring 2 two ends and the seam being fixedly connected with ring 1 and coordinating;
3, be fixedly connected with ring 1 to weld with casing inner ring 2;
4, tailor circulating water passage interval gusset 5, circulating water passage interval gusset 5 is welded on casing inner ring 2 by the requirement of Fig. 3;
5, casing inner ring 2 roughing, is machined to dimensional requirement by muscle between recirculated water 5;
6, by casing outer ring 3 side weld edge fit volume circle, be sleeved on casing inner ring 2, to casing outer ring 3 steel plate nailing, follow closely on the circulating water passage interval gusset 5 of inner ring 2, in order to fixing casing outer ring 3 and inner ring 2;
7, finally by casing outer ring two end periphery be fixedly connected with ring firm welding.
