Abstract
A sine-wave type clutch gear of a rear-driving clutch for a lawn mower, namely a sine-wave type clutch gear of a clutch device inside a rear wheel driving gear used for a self-propelled lawn mower. The sine-wave type clutch gear comprises a conical sine-wave type clutch wall of a clutch device arranged in a speed-reducing clutch of the rear wheel driving gear, and crossed shaft helical gears, and is characterized in that the inner-side conical sine-wave type clutch wall of the clutch device arranged in the speed-reducing clutch of the rear wheel driving gear is conical and wave-shaped, and a plurality of small protrusions are also formed at the end part of the conical sine-wave type clutch wall and are elliptic particularly. The utility model adopting the design not only changes the clutch device inside a low-speed claw clutch gear into the sine-wave type clutch gear so as to ensure that the clutch device inside the low-speed claw clutch gear can be applied to a higher-speed occasion, but also utilizes the end surface and the side surface to share load together, and improves the attrition heating conditions of the sole cone clutching on the inner side, so that the situation of frequent fracture of an inner pressure clutch spacer of a rear gear box of the traditional mower is improved ; and for the basis of a mechanical clutch, the sine-wave type clutch gear is the smart combination of a rigid joint manner and an attrition joint manner of a fastener. The sine-wave type clutch gear of the rear-driving clutch for the lawn mower also can widely be applied to various occasions where clutch devices are required.
Description
Technical field
The utility model relates to the clutch gear of the arrangement of clutch in a kind of rear wheel drive engagement sleeve that is used for hay mower, especially hay mower traverse gear that places such as garden, park and road next door cut the grass on a lawn.
Background technology
Hay mower is widely used in not mowing from walking the mode of not walking certainly sometimes sometimes by people's hobby is selected.The operation pedestrian spurs from walking control crank, by steel wire rope and driving lever, makes clutch block move clutch vertically.The clutch block of the arrangement of clutch in the rear wheel drive gear reduction clutch of the traverse gear of prior art is only to lean on the circular cone of clutch block side to come clutch, needs bigger axial adhesion, presses the damage phenomenon of ring washer fracture to take place frequently in causing; In engaging process, produce frictional heat between taper seat, need apply oil in the gear-box; And there is friction that relative slip, consumed power are arranged between taper seat.
Summary of the invention
For overcome the hay mower prior art the rear wheel drive decelerator in clutch due to the deficiency of duty, the utility model provides a kind of improvement of rear-guard speed-reducing clutch of hay mower traverse gear, also can be described as sinusoidal wave formula clutch gear, one can make in pressure pad sheet easy fracture not, two can make between clutch part relatively, and the duty of slip consumed power and frictional heating makes moderate progress.
The foundation of the technical scheme in the invention for solving the technical problem is:
The juncture of the fastener of mechanical clutch has friction and rigidity two big classes, and the class that rubs can be used for higher speed but easily slides and generate heat; And category of rigid has shock and vibration when for example higher speed such as jaw clutch engages; For this reason, the a plurality of little micro-protuberance that the existing inboard circular cone friction clutch of the utility model has inboard sinusoidal wave semi-rigid clutch again and strengthens zygosity, perhaps from fundamentally we can say of mechanical clutch, this is the rigidity of clutch part and the ingenious combination of friction two class junctures.
Special needs to be pointed out is that waveform of the present utility model also can adopt other waveform, for example the slightly slick and sly waveform of other multiple mathematical function or other non-precipitous broken line.
Technical solution adopted in the utility model is:
The sinusoidal wave formula clutch gear of a kind of hay mower rear-guard speed-reducing clutch, be the sinusoidal waveform clutch gear of self-moving lawn mower with the arrangement of clutch in the rear wheel drive gear reduction unit, formed by the medial surface circular cone sinusoidal waveform clutch inwall that is located at the arrangement of clutch in the rear wheel drive gear reduction clutch and kick and gear, it is characterized in that the described inside medial surface that is located at the arrangement of clutch in the rear wheel drive gear reduction clutch is circular cone or waveform particularly inwall and a plurality of kick of sine-shaped equipped clutch block are arranged, promptly with relevant clutch block equipped be the skew back taper seat of gear inside and wave mode face that sinusoidal waveform matches or other can with the face of ripple formula clutch block clutch multiple spot projection envelope etc. for example.
The beneficial effects of the utility model are: the design utilizes existing speed-reducing clutch shell and most of part, only change clutch gear and minority part such as phase accessory with it, both having improved the low speed jaw clutch is that sinusoidal wave formula clutch gear is so that it can be used for the occasion of higher speed, utilize the common load sharing in end face and side to improve the friction heating operating mode of inboard circular cone clutch gear again simultaneously, thereby can improve and press the often phenomenon of fracture of clutch block pad in the existing mower rear gear box, perhaps from mechanical clutch fundamentally, be fastener rigidity and the friction two class junctures ingenious combination.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is a profile of the present utility model.
As shown in Figure 1 to Figure 3: 1. is sinusoidal wave formula clutch inwalls among the figure;
2. is a plurality of microspikes among the figure;
3. is gears among the figure.
Embodiment
The operation pedestrian spurs from walking control crank, by steel wire rope and driving lever, clutch block is moved vertically engage.The clutch gear of the arrangement of clutch in the rear wheel drive gear reduction clutch of the traverse gear of present technique, not only the circular cone by the clutch gear medial surface engages, and what distortion was arranged is that the particularly sinusoidal wave inwall of waveform and a plurality of little micro-protuberance come assist in engagement.When the operation pedestrian unclamps from walking control crank,, clutch block is moved vertically leave this clutch gear by steel wire rope and driving lever elastic reset.Because inwall is that slick and sly sinusoidal waveform is than easier the leaving of tooth embedding clutch block.
Claims (1)
1. the sinusoidal wave formula clutch gear of a hay mower rear-guard clutch, be the sinusoidal wave formula clutch gear of self-moving lawn mower with the arrangement of clutch in the rear wheel drive gear reduction unit, formed by sinusoidal wave formula clutch wall (1) of the inboard circular cone that is located at arrangement of clutch in the rear wheel drive gear reduction clutch and a plurality of kicks (2) and the gear that are located at inner side end, be it is characterized in that the described inboard circular cone ripple clutch wall that is located at the interior arrangement of clutch of rear wheel drive gear reduction clutch is that circular cone a plurality of kicks sine-shaped and that be located at end face are ellipses or circular.
