Abstract

The utility model discloses a driving wheel of a mowing machine, which includes a solid rubber tire, an aluminum alloy hub and a nylon inner gear ring which share the same axis, wherein the tire is sleeved on the outer circumference of the hub; the inner gear ring is located in an inner hole of the hub; grooves extending in the axial direction are formed on the inner circumference surface of the hub; bosses corresponding to the grooves in shape and size are formed on the outer circumference surface of the inner gear ring; the end surface of the inner gear ring and the steps of the inner hole of the hub are in close contact and fixed connection; the lengths of three uniformly-distributed grooves on the hub are shorter than those of other grooves; the bosses on the inner gear ring corresponding to the short grooves are short bosses; and the short grooves and the short bosses are connected via bolts. The utility model integrates the metal casting driving hub and the nylon inner gear ring, so as to achieve complementary advantages, i.e. the intensity of the hub, as well as the advantages of the nylon inner gear ring in self-lubricating vibration absorption and abrasion resistance.

Description

The driving wheel of mowing machine

Technical field

The utility model relates to a kind of parts of mowing machine, especially relates to a kind of driving wheel of mowing machine.

Background technique

Domestic mowing machine commonly used generally uses the transmission part of ring gear as driving wheel at present, this driving wheel comprises tire, metal wheel hub, the ring gear that is enclosed within on the wheel hub excircle, wheel hub and ring gear are injection molded of nylon material, or are metallic material such as casting forming of aluminum alloy material.Nylon wheel hub intensity difference, fragile, can not adapt to the lawn maintenance workload that is doubled and redoubled at present, and the aluminum alloy ring gear is not wear-resisting and noise is big.

Driving wheel on the high-grade mowing machine of import generally adopts installs the steel external gear on the aluminium alloy wheel hub axle sleeve, still have the big problem of noise.

The model utility content

The technical problems to be solved in the utility model provides the driving wheel of a kind of intensity height, the wear-resisting and mowing machine that noise is low.

For solving above technical problem, the driving wheel of mowing machine of the present utility model, the metal wheel hub, the ring gear that comprise total same axis, ring gear is arranged in the endoporus of wheel hub, the inner peripheral surface of wheel hub is provided with the groove that extends vertically, the outer peripheral surface of ring gear is provided with the suitable boss of groove shapes size with the wheel hub inner circumference, and the end face of ring gear and the step of wheelboss inner hole fit, and be fixedly connected between the two.

The sectional shape of the groove of wheel hub and ring gear boss can be evenly distributed with 12 along the inner peripheral surface of wheel hub and the outer peripheral surface of ring gear respectively for trapezoidal.

As improvement of the present utility model, other groove that is shorter in length than of three uniform grooves is arranged on the wheel hub, be short boss with the corresponding boss of short groove on the ring gear, interconnect by screw between short boss and the short groove.

As another improvement of the present utility model, groove on the wheel hub and wheel hub are a single piece, and boss on the ring gear and ring gear are a single piece.

Driving wheel of the present utility model is a split-type structural, ring gear can adopt wear-resisting nylon material, high-intensity metal wheel hub and wear-resisting ring gear combine, have complementary advantages, both guaranteed the intensity of wheel hub, bring into play selflubricating absorbing of nylon ring gear and wear-resisting advantage again, reduced noise simultaneously.

Among the figure: 1 tire, 2 wheel hubs, 3 bearings, 4 ring gears, 5 grooves, the short groove of 5a, 6 boss, the short boss of 6a, 7 screws, 8 tapped holes, 9 through holes.

Embodiment

As shown in Figure 1, the driving wheel of mowing machine of the present utility model, comprise the solid tire 1, aluminium alloy wheel hub 2 of total same axis, the bearing 3 and the nylon ring gear 4 of paired mounting vertically, tire 1 is enclosed within on the excircle of wheel hub 2, nylon ring gear 4 is arranged in the endoporus of aluminium alloy wheel hub 2, and four parts are formed driving wheel with concentric circle mode assembled in sequence.

As shown in Figures 2 and 3, the inner peripheral surface of wheel hub 2 is provided with the groove 5 that extends vertically.As Fig. 4 and shown in Figure 5, the outer peripheral surface of ring gear 4 is provided with and the suitable boss 6 of wheel hub groove 5 shapes size, the sectional shape of groove 5 and boss 6 is preferably trapezoidal, be evenly distributed with 12 along the inner peripheral surface of wheel hub 2 and the outer peripheral surface of ring gear 4 respectively, the circumferencial direction of the groove 5 that matches and boss 6 realization wheel hubs 2 and ring gear 4 is fixed.Fit by the end face of ring gear 4 and the step of wheel hub 2 endoporus, and boss 6 fits towards the bottom of the end face of wheel hub and groove 5 and realizes the axially locating of ring gear 4, there are three uniform grooves to be shortened in 12 axial notches 5 on the wheel hub 2, short groove 5a bottom is respectively arranged with tapped hole 8, also be shortened with the corresponding boss of short groove 5a on the ring gear 4, be provided with the through hole 9 that is used for mounting screw 7 on the short boss 6a, short boss 6a is fixedlyed connected by screw 7 with lacking between the groove 5a.
