Abstract
The utility model discloses a ring gear and input shaft cover subassembly among washing machine transmissions, including ring gear and input axle sleeve, gear in the ring gear is helical gear, the ring gear lower extreme is equipped with the bulge loop rather than coaxial setting, evenly distributed has a plurality of lugs on the lower surface of bulge loop, form the draw -in groove between the lug, input shaft cover including the input shaft ways body and with input shaft ways body fixed connection's apron, be equipped with on the apron with the projection of draw -in groove looks adaptation. Through the improvement of above -mentioned structure, improved ring gear transmission stability in the use, the noise is little, and life is of a specified duration to be connected with the input axle sleeve is stable, improved the transmission effect.
Description
Technical field
The utility model relates to ring gear in a kind of power transmission apparatus of washing machines and power shaft grip assembly.
Background technology
Using the transmission device in washing machine at present, comprise ring gear and input axle sleeve, gear in ring gear is spur-gear wheel, ring gear is positioned at power shaft and puts and therewith rotate, its shortcoming is: ring gear is in the process of rotating, noise ratio is comparatively large, and the connection effect inputted between axle sleeve and ring gear is bad, causes transmission weak effect.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide ring gear in a kind of power transmission apparatus of washing machines and power shaft grip assembly, in washer operation process, can reduce noise, improve transmission effect.
To achieve these goals, ring gear in a kind of power transmission apparatus of washing machines designed by the utility model and power shaft grip assembly, comprise ring gear and input axle sleeve, gear in described ring gear is angular gear, described ring gear lower end is provided with coaxial bulge loop arranged with it, the lower surface of described bulge loop is evenly distributed with some projections, between described projection, forms draw-in groove; The cover plate that described input axle sleeve comprises input axle sleeve body and is fixedly connected with input axle sleeve body, described cover plate is provided with the projection suitable with described draw-in groove.The engagement of angular gear is good, stable drive, and noise is little, and on bulge loop, arrange projection and draw-in groove, and cover plate is provided with the projection suitable with draw-in groove, ring gear can be stablized with input axle sleeve and be connected, thus improve its transmission effect.
Further, described projection is fan-shaped setting, and coaxially arranges with ring gear.
Further, described projection is provided with the material reducing groove with its similar shape, and material reducing groove can reduce the weight of ring gear entirety, thus reduces costs, and can reduce the damage of ring gear under effect of inertia simultaneously.
Further, the external diameter three of the external diameter of described bulge loop, the external diameter of ring gear and projection is equal, and the internal diameter of described bulge loop is less than the internal diameter of ring gear, and the internal diameter of described projection is greater than the internal diameter of bulge loop.
A kind of fixed form between input axle sleeve body and cover plate, is provided with a through hole in the middle of described cover plate, described through hole extends to form an extending seat downwards, and described input axle sleeve body upper end to embed in described extending seat and is fixedly connected with it.
Further, described extending seat and described cover plate arc-shaped transition.
Ring gear in a kind of power transmission apparatus of washing machines that the utility model obtains and power shaft grip assembly, its technique effect is: by the improvement of said structure, improve ring gear in use transmission stability, noise is little, service life is of a specified duration, and be connected with input axle sleeve is stable, improve transmission effect.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model.
Fig. 2 is the top view of ring gear in the utility model.
Fig. 3 is the structural representation inputting axle sleeve in the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, 2, 3, ring gear in a kind of power transmission apparatus of washing machines that the utility model provides and power shaft grip assembly, comprise ring gear 1 and input axle sleeve 2, gear 3 in described ring gear 1 is angular gear, described ring gear 1 lower end is provided with coaxial bulge loop 4 arranged with it, the lower surface of described bulge loop 4 is evenly distributed with some projections 5, between described projection 5, forms draw-in groove 6; The cover plate 8 that described input axle sleeve 2 comprises input axle sleeve body 7 and is fixedly connected with input axle sleeve body 7, described cover plate 8 is provided with the projection 9 suitable with described draw-in groove 6.The engagement of angular gear is good, stable drive, and noise is little, and on bulge loop 4, arrange projection 5 and draw-in groove 6, and cover plate 8 is provided with the projection 9 suitable with draw-in groove 6, ring gear 1 can be stablized with input axle sleeve 2 and be connected, thus improve its transmission effect.
Described projection 5 is in fan-shaped setting, and coaxially arrange with ring gear 1, described projection 5 is also provided with the material reducing groove 10 with its similar shape, material reducing groove 10 can reduce the weight of ring gear 1 entirety, thus reduce costs, the damage of ring gear 1 under effect of inertia can be reduced simultaneously.
In the present embodiment, the external diameter three of the external diameter of described bulge loop 4, the external diameter of ring gear 1 and projection 5 is equal, and the internal diameter of described bulge loop 4 is less than the internal diameter of ring gear 1, and the internal diameter of described projection 5 is greater than the internal diameter of bulge loop 4.
A kind of fixed form between input axle sleeve body 7 and cover plate 8; a through hole 11 is provided with in the middle of described cover plate 8; described through hole 11 extends to form an extending seat 12 downwards; described input axle sleeve body 7 upper end to embed in described extending seat 12 and is fixedly connected with it; extending seat 12 can form protective effect to input axle sleeve body 7, described extending seat 12 and described cover plate 8 arc-shaped transition.
Ring gear in a kind of power transmission apparatus of washing machines that the utility model obtains and power shaft grip assembly, its technique effect is: by the improvement of said structure, improve ring gear 1 in use transmission stability, noise is little, service life is of a specified duration, and be connected with input axle sleeve 2 is stable, improve transmission effect.
