Two, background technology:
At present, except that planetary reduction gear, also to the gear reduction driving device be set between planetary reduction gear and bearing axle in the deceleration transmission system of public mine lift winch, just can reach desired step-down ratio.Planetary reduction gear mainly is made of centre tooth, planetary wheel and internally toothed annulus, planetary wheel meshes with centre tooth and internally toothed annulus simultaneously, centre tooth is fixed on the input shaft of planetary reduction gear, this input shaft links to each other with motor output shaft, planetary wheel is fixed on the output shaft of planetary reduction gear, the utilization planetary wheel both revolved round the sun around the central axis of centre tooth, and the principle of rotation simultaneously reaches the purpose that differential clutch is slowed down.Its clutch principle is: when the internally toothed annulus glancing impact, centre tooth can drive planetary wheel and rotate, and promptly motor can drive the load rotation; When the internally toothed annulus brake off, centre tooth can not drive planetary wheel and rotate, then motor idle running.Planetary reduction gear is widely used in the mine hoisting machinery according to little, the lightweight characteristics of its volume.But because its planetary processing and assembling all require higher precision, the cost height, installation and maintenance are very inconvenient; And noise is big at work, and wearing and tearing are generated heat its casing easy oil leakage greatly easily in the gear mesh conversion process.
Three, summary of the invention:
The purpose of this utility model provides a kind of mine lift winch clutch reductor, and in use noise is big, gear wear is fast to solve the planetary reduction gear that plays the clutch deceleration effort in traditional mine lift winch, easily heating, installation and the inconvenient problem of maintenance.
The purpose of this utility model is achieved by following technical proposals:
Mine lift winch clutch reductor, comprise input gear axle, output shaft and deceleration box, input gear axle, output shaft all by bearings on deceleration box, be engaged with one or more levels under drive gear pair between input gear axle in the deceleration box and the output shaft; Wherein the ring gear in the one-level under drive gear pair by bearings on output shaft, be fixedly connected with the connection axle sleeve on the ring gear, connecting the axle sleeve sky is enclosed within on the output shaft, and the one end stretches out deceleration box, connect the axle sleeve outer end and be engaged with brake disc by tooth, reaction plate is installed on the output shaft, and the corresponding face of brake disc and reaction plate is provided with friction lining; One side of brake disc is provided with braking bolt, is connected with stop-off nut on the braking bolt, is connected with clamping handle on the stop-off nut, is provided with surface bearing between stop-off nut and the brake disc, and stifle is with axial compression between brake disc, surface bearing and the stop-off nut.
Connecting axle sleeve in the utility model will be through the Motor torque output deceleration box of one or more levels deceleration, and be delivered on the brake disc by tooth engagement, connecting the axle sleeve sky is enclosed within on the output shaft, reaction plate is installed on the output shaft, when clamping handle drove stop-off nut and rotates on braking bolt, stop-off nut then drove brake disc and advances or retreat.When the brake disc contact reaction plate that advances, under the friction force effect between brake disc upper friction plate and the reaction plate, moment of torsion on the brake disc is delivered to and drives the output shaft rotation on the reaction plate, and promptly this mine lift winch clutch reductor is in engagement state, makes the work of motor bringing onto load; The counter-rotation clamping handle, the drive brake disc retreats, make between friction lining on the brake disc and the reaction plate and produce the gap, brake disc no longer drives reaction plate and rotates, then the rotation of motor only rotates connection axle sleeve, brake disc and stifle by under drive gear together, motor does not drive load, is equivalent to idle running.
The utility model has the advantages that: deceleration transmission and arrangement of clutch constitute an an organic whole, can reach high step-down ratio, and clutch is reliable, and noise little, be difficult for heating and leakage of oil, low, the installation and easy to maintenance of cost.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
The meaning of each label is among the figure: 1 input gear axle, and 2 output shafts, 3 deceleration box, 4 ring gears, 5 connect axle sleeve, 6 brake discs, 7 reaction plates, 8 friction linings, 9 braking bolts, 10 stop-off nuts, 11 clamping handles, 12 surface bearings, 13 stifles, 14 bearings, 15 bearings.
Five, the specific embodiment:
In Fig. 1, input gear axle 1, output shaft 2 all by bearings on deceleration box 3, input gear axle 1 is formed one-level under drive gear pair with the ring gear 4 on the output shaft 2 in the deceleration box 3, ring gear 4 by bearings on output shaft 2, be bolted to connection on the ring gear 4 and connected axle sleeve 5, connecting axle sleeve 5 skies is enclosed within on the output shaft 2, and the one end stretches out deceleration box 3, connect axle sleeve 5 outer ends and be engaged with brake disc 6 by tooth, reaction plate 7 is installed on the output shaft 2, and brake disc 6 is provided with friction lining 8 with reaction plate 7 corresponding faces; One side of brake disc 6 is provided with braking bolt 9, be connected with stop-off nut 10 on the braking bolt 9, be connected with clamping handle 11 on the stop-off nut 10, be provided with surface bearing 12 between stop-off nut 10 and the brake disc 6, stifle 13 is with axial compression between brake disc 6, surface bearing 12 and the stop-off nut 10.Surface bearing 12 makes between stop-off nut 10 and the brake disc 6 only in transfers power.
