Wherein, said assembly is by unilateral bearing, nut, main shaft; Master gear, friction plate and clamping plate are formed, and said main shaft is erected by Zuo Gai and You Gai through bearing; The interior ring and the master gear of said nut, friction plate, clamping plate, unilateral bearing are installed on the main shaft, and said unilateral bearing is positioned at clamping plate and friction plate, and its outer shroud is fixed on the right side and covers; Nut places a side of friction plate, and said master gear is positioned at a side of nut, and said master gear docks with the nut convex-concave.
On the said seat of honour, be fixed with wheel frame and basket seat, another basket seat is fixed on down on the seat, and said retarder is fixed on the hanging basket through the basket seat, on said wheel frame, is provided with guide wheel, and pinch roller links to each other with guide wheel with torsion spring through pinch roller frame.
The advantage and the beneficial effect of the utility model are: this speed reducer that is provided with self-locking mechanism is novel in design, directly in housing, forms engaging tooth, so just can form sealing configuration, accomplishes oil-proofly, does not advance foreign matter, and is non-maintaining, and volume is little; Adopt unilateral bearing to realize self-locking, can accomplish that fine motion can lock, safety coefficient is high, and strength character is good.Can be widely used in relevant high-lift operation such as construction, high building cleaning, exterior wall brushing, elevator installation.
Description of drawings
Fig. 1 is the speed reducer structural representation that the utility model is provided with self-locking mechanism;
Fig. 2 is the speed reducer structure sectional view that the utility model is provided with self-locking mechanism;
Fig. 3 is the speed reducer embodiment schematic representation that the utility model is provided with self-locking mechanism.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
Like Fig. 1, shown in Figure 2, the utility model is a kind of speed reducer that is provided with self-locking mechanism, mainly comprises left side lid 3, right lid 4, following seat 9, the seat of honour 17, assembly 18, duplicate gear 5, bull gear 12, idle wheel 13.Assembly 18 is by unilateral bearing 14, nut 6, and main shaft 7, master gear 8, friction plate 10 is formed with clamping plate 11.Left side lid 3, right lid 4 be an integral mechanism with bull gear 12, assembly 18, duplicate gear 5, idle wheel 13, is positioned at the enclosed construction of left side lid 3, right lid 4 and bull gear 12 compositions.Master gear 8 meshes with the gearwheel of duplicate gear 5, the small gear of duplicate gear 5 and idle wheel 13 engagements, idle wheel 13 and bull gear 12 engagements.Main shaft 7 is erected by left side lid 3 and right lid 4 through bearing, and the interior ring and the master gear 8 of nut 6, friction plate 10, clamping plate 11, unilateral bearing 14 are installed in respectively on the main shaft 7.Unilateral bearing 14 is in clamping plate 11 and the friction plate 10, and its outer shroud is fixed on the right lid 4.Nut 6 places a side of friction plate 10, and master gear 8 places a side of nut 6, and master gear 8 docks with nut 6 convex-concaves; Said gear, idle wheel and gear ring are helical teeth or gear with helical teeth.
Working principle: on main shaft, add power source, the drive main shaft rotates, and rotates thereby drive main tooth, and gland nut and friction plate push unilateral bearing simultaneously, and master gear, nut, friction plate and unilateral bearing do not have relative movement at this moment.Master gear drives the canine tooth in the duplicate gear, and the small gear in the duplex tooth opinion drives idle wheel, and idle wheel drives bull gear and rotates, thereby has accomplished the secondary transmission; During self-locking, because the load-carrying action of gravity of speed reducer, make bull gear clockwise, the duplex tooth reverses, and master gear is clockwise, extrusion friction sheet and clamping plate to the right, and the interior ring of clamping plate clamping unilateral bearing makes the unilateral bearing self-locking.
Embodiment
As shown in Figure 3, the utility model is used as the speed reducer of pedal hanging basket.Stator ring frame 1 and basket seat 16 on the seat of honour 17, another basket seat 16 is fixed on down on the seat 9.Through basket seat 16 the utility model is fixed on the hanging basket.Guide wheel 2 is arranged on the wheel frame 1, and pinch roller 19 links to each other with guide wheel 2 with torsion spring 21 through pinch roller frame 15.On main shaft 7, adding a pedal, is power with manpower pedal.Outside the bull gear 12 " V " type groove is arranged, wire rope 20 passes " V " type groove, three trains that bull gear 12, guide wheel 2 and pinch roller 19 constitute, and wire rope 20 forms " Q " shapes trend.The gravity of hanging basket and load makes in " V " type groove wire rope 20 produce huge frictional force also just is enough to guarantee hanging basket and the load required gravitation of dragging that goes up and down.
Working procedure:
Hanging basket rises: a drive rotation clockwise, rotate thereby drive main tooth, and gland nut and friction plate push unilateral bearing simultaneously, and main tooth, screw, friction plate and unilateral bearing do not have relative movement at this moment.The canine tooth of the moving duplex tooth of main cingulum, the little cingulum of duplex tooth moves idle wheel, and idle wheel drives bull gear, thereby has accomplished the secondary transmission, and hanging basket rises.
Descend: drive axle counterclockwise and rotate, promptly hanging basket descends.
Stop: no matter in process of rising or falling, when desiring to stop, moment hanging basket downward trend is all arranged, just bull gear is clockwise; The duplex tooth reverses, and main tooth is clockwise, to the right extrusion friction sheet and clamping plate; Clamping plate clamp the interior ring of unilateral bearing, make the unilateral bearing self-locking, and hanging basket stops.
The all right connection gear of the utility model, belt pulley, chain etc. use as speed reducer.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
