Abstract
A screw water intake type cooling electric machine consists of a front cover (1), a stator (4), a rotor (8), a back cover (10), a gland (11) and a casing (16). In order to simplify structure, reduce size and weight, eliminate noise, enable easy assembly and carryover, the utility model adopts a cylinder sleeve (5) with stopping platform (17) and the cast aluminum casing (16) comprising a water inlet (14), a water outlet (3) and the water jacket (7) of an air exhaust hole (9).
Description
The utility model relates to a kind of spiral inlet type cooling motor that is applicable to that portable power tool uses.
At present, the motor that portable power tool adopted mostly is ventilated motor, this motor adopts iron shell, have radiating fin on the shell again, the motor interior design has fan, thereby, increased the volume and weight of motor, make structure comparatively complicated, in installation and use, increased the difficulty of assembling and the inconvenience of carrying.And the employing of air-cooled structure has also increased noise factor.
The purpose of this utility model is developed a kind of spiral inlet type cooling motor exactly.The utility model can reduce volume and weight effectively, and simplified structure reduces noise, and is convenient for assembly and carry.
For achieving the above object, the technical solution of the utility model is: the utility model is made up of protecgulum, stator, rotor, bonnet, gland, shell.Protecgulum and shell link together by binding thread, and bonnet is connected by fastening bolt with shell, and gland is fixed on the bonnet.The utility model has adopted by cylinder sleeve that has the stop platform and the water jacket that has water inlet and delivery port and has been enclosed in the cast aluminium shell of forming together by sealing ring.
The gap thickness that forms between the utility model cylinder sleeve and the water jacket is at 1.5-3mm; Its inner sealing pressure maximum can reach 0.4Mpa; The utility model can adopt the water jacket that has steam vent; The utility model water jacket inwall have can with the spiral salient of outer wall of cylinder jachet fluid-tight engagement; The gap optimum thickness that forms between the utility model cylinder sleeve and the water jacket is 2mm.
Compare with conventional art, the utility model is enclosed in the shell of forming together owing to having adopted by cylinder sleeve and the water jacket that has water inlet and delivery port by sealing ring, required radiating fin of air-cooled structure and fan have been removed, thereby structure is simpler and compact, noise reduces during use, the employing of cast aluminium shell, alleviated weight, thereby convenient assembling and portably using, the design of water jacket spiral inner wall projection, between water jacket and cylinder sleeve, form the spirality space, made cooling water flow twist, strengthened cooling effect.
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the profile of an embodiment of the utility model.
As shown in the figure, protecgulum (1), sealing ring (2), delivery port (3), stator (4), cylinder sleeve (5), gap (6), water jacket (7), rotor (8), steam vent (9), bonnet (10), gland (11), fastening bolt (12), sealing ring (13), water inlet (14), spiral salient (15), shell (16), stop platform (17), binding thread (18).
As figure, during assembling the utility model, the cylinder sleeve (5) that stator (4) is packed into and had stop platform (17) at first, by binding thread (18) protecgulum (1) and cylinder sleeve (5) are connected, load onto the rotor (8) that has combined, on cylinder sleeve (5), put the water jacket (7) that has water inlet (14), delivery port (3) and steam vent (9) again, because the acting in conjunction of the spiral salient (15) of water jacket (7) inwall and sealing ring (13), sealing ring (2), water jacket (7) forms spiral seal clearance (6) with cylinder sleeve (5), and forms shell (16) jointly with cylinder sleeve (5).In the cover process of assembling, unnecessary gas can pass through steam vent (9) discharge in gap (6).Afterwards, bonnet (10) and shell (16) are linked together, at this moment,, make the fixed-site of water jacket (7) owing to the acting in conjunction of stop platform (17) and bonnet (10) with fastening bolt (12).After rotor (8) carried out necessary adjustment, load onto gland (11) and promptly assemble and finish.In the present embodiment, adopted cast aluminium shell (16), gap (6) thickness that forms between cylinder sleeve (5) and the water jacket (7) is 2mm, inner sealing pressure up 0.4MPa.
