The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.Fig. 1, Figure 1A, be low-noise decelerator for washing machine of the present invention, its reduction gearing mechanism is the dead axle transmission formula, mainly by housing 1, power shaft 2, driving wheel 3, driven pulley 4a, 4b, breast wheel 8a, 8b, fixed tensioning wheel 7a and auto-tensioning wheel 7b and output shaft 6,6a forms, be linked together by two-sided polywedge bet 5, driving wheel 3 is packed on the power shaft 2, driven pulley 4a, 4b is packed on the output shaft 6, breast wheel 8a, 8b, output shaft 6 is movably arranged on the housing 1, driving wheel 3, driven pulley 4a, 4b, breast wheel 8a, 8b, regulating wheel 7a, 7b is provided with multiple wedge slot 13, and two-sided polywedge bet 5 is installed on the multiple wedge slot 13; Fixed tensioning wheel 7a directly is movably arranged on the housing 1, and auto-tensioning wheel 7b is movably arranged on an end of lever support 10, and the centre of lever support 10 is provided with fulcrum 9, and the other end is installed on the steady pin 12 by extension spring 11, and steady pin 12 is packed on the housing 1.Because the auto-tensioning wheel can be realized the constant tension state, can guarantee that transmission is non-slip, running steadily.Because be provided with auto-tensioning wheel 7b, two-sided polywedge bet 5 can keep tensioning state, has guaranteed the stationarity of transmission.The cornerite of two-sided polywedge bet 5 on driving wheel 3 is that α 1 is 212 °, the cornerite of two-sided polywedge bet 5 on a driven pulley 4a is that α 2 is 162 °, the cornerite of two-sided polywedge bet 5 on another driven pulley 4b is that α 3 is 230 °, these cornerites are all greater than 140 °, if cornerite is too small, because the basic rated power that every wedge transmitted is certain value, transmission efficiency can decrease like this.
Power shaft 2 upper ends reach above the decelerator, become center output shaft 6a.
Fig. 2,2A, cross sectional representation for the two-sided polywedge bet of low-noise decelerator for washing machine of the present invention, the structure of two-sided polywedge bet is on the matrix of wire rope core structure flat rubber belting, the endless belt that some vertical triangle wedges are all arranged up and down, the upper and lower of its cross section is the triangle that profile of tooth is arranged, working face is a wedge surface, two kinds of rubber and polyurethanes are arranged, it has the softness of flat rubber belting, the characteristics that V-belt frictional force is big, simultaneously owing to its two-sided can engagement, so be specially adapted to the transmission of compact conformation with drive; Test shows that it is than V-belt stable drive, and transmitted power is big, the efficient height, and speed is fast, and gearratio is big, and contour dimension is little, is particularly suitable for more than the requirement V-belt radical or the transmission of wheel shaft vertical ground; Its cross section up and down triangular tooth is furnished with staggered and two kinds of symmetric forms.
Fig. 3,3A are low-noise decelerator for washing machine multiple wedge slot wheel profile schematic diagram of the present invention, and wherein Fig. 3 is overall outer hoist pennants, and Fig. 3 A is the partial enlarged drawing of Fig. 3; Owing on driving wheel 3, driven pulley 4a, 4b, breast wheel 8a, 8b, fixed tensioning wheel 7a and auto-tensioning wheel 7b, all be provided with multiple wedge slot 13, the shape of multiple wedge slot 13 is corresponding with the profile of tooth of two-sided polywedge bet 5, like this, two-sided polywedge bet 5 can be well passes to driven pulley 4a, 4b reposefully with the power of driving wheel 3, make 6 of power shaft 2 and output shafts realize good deceleration transmission effect, reach the purpose that reduces noise.
Below in conjunction with accompanying drawing 1, Figure 1A the working method of low-noise decelerator for washing machine of the present invention is briefly explained:
Power shaft 2 forward and backwards → driving wheel 3 forward and backwards → breast wheel 8a instead, just change → fixed tensioning wheel 7a instead, just change → driven pulley 4a forward and backward → breast wheel 8b instead, just change → auto-tensioning wheel 7b forward and backward → driven pulley 4b instead, just change, so just realized that two driven pulley 4a, 4b are by opposite direction rotation, the speed ratio of having got back and having needed, running is steady, and noise is little.
