Abstract
A worm & gear reduction gear, in the field of reduction gear equipment, comprises a worm, a worm wheel and a case body. The case body is fixed to connect with an end cover through bolts. The worm meshes with the worm wheel; an output shaft is installed in the center of the worm wheel; the output shaft is movably supported inside the case body. The utility model is characterized in that the worm (3) is connected with a hydraulic /pneumatic power source. The utility model has the advantages of small volume, light weight, compact structure, rather stable working, easy to fulfill overload protection, hydraulic elements being self-lubricated and long service life and etc. A double-face oil seal is utilized between the output shaft and the end cover, for which perfect sealing performance can be guaranteed.
Description
Technical field
The utility model belongs to the speed reducer apparatus field, is specifically related to a kind of worm-gear speed reducer.
Background technique
At present, worm-gear speed reducer adopts belt transmission, and belt elasticity sliding motion easily takes place and skids, and transmission efficiency is low and can not keep velocity ratio accurately, and the pressure ratio of bearing on the axle is bigger, and the life-span of belt is shorter.
The model utility content
Technical problem to be solved in the utility model provides that a kind of volume is little, the worm-gear speed reducer of compact structure, long service life.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted is: this worm-gear speed reducer, comprise worm screw, worm gear and casing, casing is bolted to connection end cap, worm and wheel is meshed, output shaft is installed at the center of worm gear, and the output shaft movable supporting is characterized in that in casing: worm screw connects the hydraulic/pneumatic power source.The hydraulic/pneumatic power source is oil hydraulic motor or pneumatic cylinders.
Adopt double-sided oil seal between output shaft and the end cap.Improve sealing effect.
Working procedure: oil hydraulic motor drives the worm screw rotation, and worm screw drives the worm gear rotation, the rotation of worm gear drives output shaft.
Compared with prior art the beneficial effect that the utility model had is: because the utility model adopts the oil hydraulic motor transmission, overcoming belt elasticity sliding motion easily takes place and skids, transmission efficiency is low and can not keep velocity ratio accurately, the pressure ratio of bearing on the axle is bigger, the problem that the life-span of belt is short.Make the volume-diminished of equipment, in light weight, compact structure, work more steadily, easily realizes overload protection, and hydraulic element can lubricate voluntarily, and working life is longer.Adopt double-sided oil seal between output shaft and the end cap, make that the sealing of equipment is good.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a right elevation of the present utility model.
Embodiment
1 oil hydraulic motor, 2 worm gears, 3 worm screws, 4 output shafts, 5 bearings, 6 casings, 7 oil sealings, 8 end caps.
Shown in Fig. 1-2, worm-gear speed reducer, form by oil hydraulic motor 1, worm gear 2, worm screw 3, output shaft 4, bearing 5, casing 6, oil sealing 7, end cap 8, casing 6 is bolted to connection end cap 8, worm screw 3 is meshed with worm gear 2, output shaft 4 is installed at the center of worm gear 2, and output shaft 4 movable supporting are in casing 6, and worm screw 3 connects the hydraulic/pneumatic power source.
The hydraulic/pneumatic power source is oil hydraulic motor 1 or pneumatic cylinders.
Oil hydraulic motor 1 connects worm screw 3, and worm screw 3 is meshed with worm gear 2, and output shaft 4 is installed at the center of worm gear 2, and in casing 6, fixedly connected with end cap 8 by bolt by casing 6 by bearing 5 movable supporting for output shaft 4, adopts double-sided oil seal 7 between output shaft 4 and the end cap 8.
Working procedure: oil hydraulic motor 1 drives worm screw 3 rotations, and worm screw 3 drives worm gear 2 rotations, and worm gear 2 drives output shaft 4 rotations.Realize speed change.
