Abstract
A small belt pulley device of a split type washing machine comprises a fan impeller 1, an insert 2 and a belt pulley 3. The fan impeller 1 and the belt pulley 3 are connected through uniformly distributed pin bosses 33 in a certain number. The belt pulley 3 is fastened on an output shaft of a washing motor through a threaded hole 32. The fan impeller 1 is a plastic part, and a plurality of fan blades 11 are uniformly distributed on the fan impeller 1 and used for cooling the washing motor. The belt pulley 3 is a plastic part while the insert 2 is a metal part. The insert 2 is nested in the belt pulley 3 during injection molding of the belt pulley 3 and used for increasing strength of the belt pulley during torque transmission. A plurality of reinforcing ribs 34 are distributed on the belt pulley 3 and used for reinforcing the belt pulley. The motion of the washing motor is transmitted to a large belt pulley by connecting a belt pulley groove 31 with a triangular belt. The small belt pulley device of the split type washing machine is simple in structure and manufacture process, reliable in connection, convenient to mount and demount, low in cost, good in quality uniformity and convenient to popularize and apply.
Description
Affiliated technical field
The utility model relates to a kind of device for washing machine, especially relates to a kind of small pulley device of pulsator washing machine.
Background technology
Rotary drum washing machine, be mainly by impeller positive and negative rotation rhythmically, produces certain washing current, washes away clothing, and constantly friction between washing clothes, washtub and impeller etc. simultaneously, make dirt break away from clothing, realizes the cleaning to clothing.The positive and negative rotational power of agitation wheel for washing machine is from washing motor, and concrete bang path mainly comprises washing motor, small pulley, V-belt, large belt wheel, gear-box and impeller, and wherein small pulley is to be assemblied on the output shaft of washing motor.Small pulley comprises flabellum part, wheel slot part and the several funtion parts of tightening part, realizes both having transmitted the power of washing motor, the function of again washing motor being lowered the temperature.
At present, small pulley is generally aluminum casting, then processes by Seiko, its manufacturing technique complexity, and quality conformance is poor, and cost is higher; Also the useful part working of plastics replaces the utility model of flabellum part, but the manufacturing technique complexity of wheel slot part and tightening part is still relatively complicated, and cost is still relatively high.
Summary of the invention
In order to overcome the manufacturing technique complexity of existing washing motor small pulley device, quality conformance is poor, the high in cost of production defect, and the utility model provides a kind of split type washing machine small pulley device.
The utility model specifically solves the technical solution that its technical problem adopts: a kind of detachable washing machine small pulley device comprises Vane wheel 1, inserts 2 and belt wheel 3.Wherein, Vane wheel 1 is realized connecting by all distribution boss 33 of some on belt wheel 3, and inserts 2 is embedded into its inside when belt wheel 3 injection moulding, and belt wheel 3 is tightened on the output shaft of washing motor by screwed hole 32.Vane wheel 1 is working of plastics, is uniformly distributed the fan sheet 11 of some on it, for realizing the function that washing motor is lowered the temperature; Belt wheel 3 is working of plastics, by pulley groove 31, connects V-belt, realizes that the washing motor motion is to large belt wheel transmission, and the reinforcement 34 of distribution some on belt wheel 3, for strengthening the bulk strength of belt wheel 3; Inserts 2 is metalwork, in belt wheel 3 injection moulding process, is embedded in inside, for strengthening the intensity of belt wheel 3 in the transmitting torque process.
The beneficial effects of the utility model are, adopt a kind of detachable washing machine small pulley device, solved the manufacturing technique complexity of current washing machine small pulley device, the problem such as quality conformance is poor, and cost is higher, it is simple in structure, manufacturing technique is simple, connects reliably, and installation and removal are convenient, with low cost, greatly improved the quality conformance of washing machine small pulley device.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model patent is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation top view (for symmetrical view).
1. Vane wheels in figure, 11. fan sheets, 2. inserts, 3. belt wheel, 31. pulley groove, 32. screwed holes, 33. pin boss, 34. reinforcements.
The specific embodiment
Referring to accompanying drawing, a kind of detachable washing machine small pulley device comprises Vane wheel 1, inserts 2 and belt wheel 3.Wherein, Vane wheel 1 is realized connecting by all distribution boss 33 of some on belt wheel 3, and inserts 2 is embedded into its inside in belt wheel 3 injection moulding process, and belt wheel 3 is tightened on the output shaft of washing motor by screwed hole 32.Vane wheel 1 is working of plastics, is uniformly distributed the fan sheet 11 of some on it, for realizing the function that washing motor is lowered the temperature; Belt wheel 3 is working of plastics, by pulley groove 31, connects V-belt, realizes that the washing motor motion is to large belt wheel transmission, and the reinforcement 34 of distribution some on belt wheel 3, for strengthening the bulk strength of belt wheel 3; Inserts 2 is metalwork, is to be embedded in plastics inner in belt wheel 3 injection moulding process, and inserts 2 and belt wheel 3 is the injection moulding assembly, for strengthening the intensity of belt wheel 3 in the transmitting torque process, improves detachable washing machine small pulley device lifetime.
In carrying out detachable washing machine small pulley device assembling process, first Vane wheel 1 is installed to the output shaft of washing motor, top bar and realize location with the output shaft of washing motor, while needing to adjust the height of Vane wheel 1, can top bar and place certain thickness adjustment pad at the output shaft of washing motor in advance; Again inserts 2 and belt wheel 3 injection moulding assemblies are installed on the output shaft of washing motor, make on belt wheel 3 equally distributed pin boss 33 corresponding with the connecting hole on Vane wheel 1, and compress and realize connecting; (caption does not mark to use specific washing machine small pulley device tight fixed bolt assembly, bolt assembly comprises screw bolt and nut) carry out tightening, wherein bolt is for being tightened to the output shaft of washing motor by screwed hole 32, certain tightening torque demand is arranged, nut is for after the bolt tightening, tightening between clamping screw and clothing machine small pulley device, the tightening between the output shaft that washing machine small pulley device and washing motor occur during the course of avoiding moving is become flexible; Finally with V-belt, connect the pulley groove 31 of washing machine small pulley device and the pulley groove of large pulley arrangement.
