Background technique
Northern area cold in winter through snowing a great deal, usually because of accumulated snow waits obstruction before causing high-grade highway, urban road, country road and room behind the house, can not normally be driven a vehicle, and brings inconvenience for driving and pedestrian.In order to guarantee that the roads were clear of traffic, need in time to remove accumulated snow, remove the accumulated snow way now and mainly contain: artificial snow removing, chemical solvent snow removing and snow removal with machine.The general employing of artificial snow removing pushes away, shovels, sweeps mode, and its shortcoming is to waste time and energy, and efficient is low, only the place of suitable small size.Though chemical solvent snow removing is simply saved trouble, snow melting agent can road pavement produce chemical etching, shortens road working life, also has the problem that surrounding environment is produced severe contamination simultaneously.Snow removal with machine is the most effective snow-removing method at present, and the speed of not only sweeping away snow is fast, snow removing efficient height, and the snow removing cost is low, can not produce environmental pollution, therefore, fast, the economical and practical small-sized snowplow of the various speed of sweeping away snow arises at the historic moment, and is applied rapidly.But present small-sized snowplow has the following disadvantages: the one, because worm gear case adopts the opening and closing left and right structure, and can not be concentric when output shaft is installed, the transmission resistance is big, causes easily and beats, poor stability.The 2nd, in small-sized snowplow swept away snow process, power cannot clutch, brought potential safety hazard for the work of sweeping away snow.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not find solution preferably as yet so far.
Summary of the invention
For overcoming the above-mentioned defective that existing snowplow variable speed drive exists, the purpose of this utility model provide a kind of simple and reasonable, good concentricity, rotation flexibly, stable drive, the reliable snowplow clutch type of power clutch variable speed drive.
The technological scheme that its technical problem that solves the utility model adopts, it comprises worm gear case, the worm gear case lid, worm gear, clutch slider, the clutch dial, output shaft, worm screw, belt pulley, described worm gear case and worm gear case lid are separate type up and down, worm gear is rotating to be arranged on the output shaft, clutch slider can be arranged on the output shaft in axial sliding, be provided with the clutch latch that matches between worm gear and the clutch slider, output shaft is arranged on the worm gear case by output shaft bearing is rotating, the clutch dial is rotating to be arranged between worm gear case and the worm gear case lid, shift fork headgear on the clutch dial is located on the allocating slot of clutch slider, and the rotating shaft of clutch dial is fixed with pivoted arm after stretching out the worm gear case lid; Described belt pulley is fixed on the worm screw by link, and worm screw is arranged on worm gear case and Worm gear case covers, worm gear and worm meshing by worm bearing is rotating.
Described output shaft is provided with the pad of regulating worm gear and worm screw matching gap, and pad is arranged between worm gear and the output shaft bearing.
Correspondence is provided with the output shaft oil sealing that matches with output shaft on the described worm gear case, and output shaft oil sealing correspondence is arranged on the outer side surface of output shaft bearing.
Be provided with the worm screw oil sealing that matches with worm screw between described worm gear case and the worm gear case lid, worm screw oil sealing correspondence is arranged on the outer side surface of worm bearing.
After adopting said structure, following advantage and effect are arranged compared with the prior art, the one and since worm gear case and worm gear case lid be about separate type, output shaft is installed on the worm gear case by the output shaft bearing of both sides is rotating, output shaft is installed good concentricity, stability of rotation can not cause and beat.The 2nd, be arranged on the output shaft because worm gear is rotating, clutch slider can be arranged on the output shaft in axial sliding, be provided with the latch that matches between worm gear and the clutch slider, the clutch dial is rotating to be arranged between worm gear case and the worm gear case lid, shift fork headgear on the clutch dial is located on the allocating slot of clutch slider, the rotating shaft of clutch dial is fixed with pivoted arm after stretching out the worm gear case lid, when the operation pivoted arm, pivoted arm drives the clutch dial and rotates, shift fork head on the clutch dial drives clutch slider and moves axially, clutch slider is separated with worm gear, worm gear idle running, thus realize that power separates.The 2nd, can regulate worm gear and worm screw matching gap by the thickness of pad, make adjusting worm gear and worm meshing reliable.The 3rd, Worm gear case is provided with worm screw oil sealing and the output shaft oil sealing with worm screw and output shaft corresponding matching, can be oil-proof or oil-tight by protecting Worm gear case, guarantee that worm gear and worm screw are lubricated reliable.
