Background technique
Worm-gear speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, and the winding number of motor is decelerated to desired winding number, and obtains the mechanism of larger torque.All can use in the transmission system of various machinery, from boats and ships, automobile, the locomotive of the traffic tool, heavy machinery for building, the machining machine and tool that mechanical industry is used and automated production equipment, household electrical appliances common in daily life, clock and watch etc., its application is from the transmission work of large power, to Smaller load, accurate angle transmission all can see the application of speed reducer, is therefore widely used in the conversion equipment of speed and moment of torsion.The effect of speed reducer mainly reduction of speed improves output torque simultaneously, and moment of torsion export ratio exports by motor and takes advantage of reduction speed ratio; Slow down and reduce the inertia of load simultaneously, inertia be reduced to reduction speed ratio square.Worm reduction gear basic structure formed primarily of driving parts worm and gear, axle, bearing, casing and annex thereof, can be divided into and have three large basic structure portion casings, worm and gear, bearing and axle to combine, casing is the pedestal of all accessories in worm-gear speed reducer, is supporting and fixing shaft components.
But the output screw of tradition machinery and worm-gear toothing direct-drive, cannot overcome the worm-gear toothing of product and the torsion of screw rod and frictional force, make worm-gear toothing not wear-resisting, the life-span is not long.Therefore, for above aspect, need reasonably to improve prior art.
Model utility content
For above defect, the utility model provides one to be conducive to reducing frictional force, efficacy, makes the worm gear reducer device that the worm-gear toothing life-span is longer, durable, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of worm gear reducer device, comprise gear box cover, input screw rod, described input screw rod is arranged at gear box cover side, installs worm-gear toothing on rear side of described gear box cover;
Input screw rod to be wherein arranged at above worm-gear toothing and input screw rod wherein one end with external gear;
Meanwhile, between input screw rod and worm-gear toothing, set up the driving mechanism be made up of gear I and gear II;
Gear I wherein engages with external gear, and gear II wherein engages with worm-gear toothing, thus defines a sets of transmission mechanism between input screw rod and worm-gear toothing.
Described gear I can be set to coaxial configuration with gear II;
On rear side of described gear box cover 1, outward edge is with some locating columns;
The diameter of described gear I is greater than gear II;
Described gear I is on same level height with the axle center of each axis of rotation of gear II.
The beneficial effect of worm gear reducer device described in the utility model is:
Between input screw rod end and worm-gear toothing, two miniature gears are set, accept the gearing between input screw rod and worm-gear toothing, utilize one end of this cover miniature gear I and input screw gear connection for transmission, another miniature gear II is connected with worm-gear toothing, reach gearing, reduce frictional force, efficacy, make the worm-gear toothing life-span longer, durable.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of worm gear reducer device described in the utility model embodiment.
In figure:
1, gear box cover; 2, screw rod is inputted; 3, external gear; 4, worm-gear toothing; 5, gear I; 6, gear II.
