Abstract
The utility model discloses a careless device is prevented twining by gear box, including gear case housing, snap rings for hole, first bearing, little bevel gear, key axle, second bearing, big bevel gear, oil blanket, third bearing, clamp plate, flange and the head of beating the grass, little bevel gear passes through second bearing and third bearing and gear case housing cooperation location through first bearing and gear case housing cooperation location, key axle, and big bevel gear passes through the spline and is connected with the key shaft fit, and big bevel gear passes through key axle threaded connection through spline fit and key hub connection, the head of beating the grass with gear case housing with little bevel gear meshing, flange. The device simple structure, it is epaxial effectually to prevent that weeds from twining the key, improves the efficiency of beating the grass.
Description
Technical field
The utility model relates to a kind of gear box device, specifically the anti-tangle careless device of a kind of gear-box.
Background technique
Mowing machine is in the process of beating the grass, and often have the phenomenon generation that gear-box key axle is wound around a lot of weeds in moving head beats the grass process, the rotating speed of extreme influence gear-box key axle, affects the practical efficiency of beating the grass.
Summary of the invention
The purpose of this utility model is to provide a kind of gear-box anti-tangle careless device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
The anti-tangle careless device of a kind of gear-box, comprises gear box casing, hole back-up ring, clutch shaft bearing, bevel pinion, key axle, the second bearing, bevel gear wheel, oil sealing, the 3rd bearing, pressing plate, flange and moving head; Bevel pinion to be coordinated with gear box casing by clutch shaft bearing locates, key axle is coordinated with gear box casing by the second bearing and the 3rd bearing locates, bevel gear wheel is connected by spline and key axle, bevel gear wheel engages with bevel pinion, flange is connected with key axle by spline fitted, and moving head is connected by key male thread with gear box casing.
As further program of the utility model: clutch shaft bearing, the second bearing and the 3rd bearing are all two.
As the utility model further scheme: the gap of moving head and flange will control within 0.5mm.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, can effectively prevent weeds to be wound on key axle, improve efficiency of beating the grass.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-tangle careless device of gear-box.
Fig. 2 is the structural representation of flange in the anti-tangle careless device of gear-box.
Fig. 3 be in the anti-tangle careless device of gear-box flange generalized section.
Wherein: 1-gear box casing, 2-hole back-up ring, 3-clutch shaft bearing, 4-bevel pinion, 5-key axle, 6-second bearing, 7-bevel gear wheel, 8-oil sealing, 9-the 3rd bearing, 10-pressing plate, 11-flange, 12-moving head.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1-3, the anti-tangle careless device of a kind of gear-box, comprise gear box casing 1, hole back-up ring 2, clutch shaft bearing 3, bevel pinion 4, key axle 5, second bearing 6, bevel gear wheel 7, oil sealing 8, the 3rd bearing 9, pressing plate 10, flange 11 and moving head 12.Bevel pinion 4 is coordinated with gear box casing 1 by two clutch shaft bearings 3 locates, key axle 5 is coordinated with gear box casing 1 by the second bearing 6 and the 3rd bearing 9 locates, bevel gear wheel 7 is connected by spline and key axle 5, bevel gear wheel 7 engages with bevel pinion 4, flange 11 is connected with key axle 5 by spline fitted, and moving head 12 is threaded by key axle 5 with gear box casing 1.
Working principle of the present utility model is: start grass-mowing machine, transmission shaft drives bevel pinion 4 to rotate by spline, bevel pinion 4 engages with bevel gear wheel 7 and then drives bevel gear wheel 7 to rotate, and bevel gear wheel 7 drives flange 11 and moving head 12 to rotate by spline and key axle 5, carries out operation of beating the grass.In the process of beating the grass, flange 11 is with moving head 12 synchronous rotary and within the two gap control to 0.5mm, can effectively prevent grass from twining on key axle 5, improves efficiency of beating the grass.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
