Description
Technical field
The utility model relates to a kind of worm reduction gear.
Background technique
As everyone knows, worm reduction gear 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.Worm reduction gear has been applied in mechanical processing industry widely as a kind of conventional retarding device.Along with increasing of machining needs, the requirement of retarding device is also increased thereupon, not only requires that transmission accuracy is high, bearing capacity large, long service life, and require the compact structure of speed reducer own, save space, existing speed reducer equipment can not meet such requirement.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides that a kind of precision is high, bearing capacity is large, the life-span is long, the worm reduction gear of compact structure.
For achieving the above object, the technical solution of the utility model there is provided a kind of worm reduction gear, comprises worm gear and the worm screw of the transmission that cooperatively interacts, and described worm gear and worm screw outer installment have the frame coordinated with worm gear and worm screw; Described worm screw is provided with the worm drive tooth with worm gear, and described worm drive tooth is arranged on a plane-generated double enveloping anchor ring, and described worm gear is provided with worm drive tooth, and described worm drive tooth engages with worm drive tooth; Described worm gear center is provided with output shaft, and it is shaping that described output shaft and worm gear pass through spheroidal graphite cast iron integrally casting; Described worm screw is connected with drive motor by coupling.Speed reducer described in the utility model improves transmission accuracy and bearing capacity and working life by using planar double-enveloping worm, simultaneously by output shaft and worm gear integrally casting, obtains comparatively compact structure.
As preferably, described plane-generated double enveloping anchor ring is the thinner arc ring concave surface in thicker center, two ends.Such design is the further optimization to scheme.
As preferably, described frame is spliced by left shell and right shell body, and described frame lower end is provided with base, and described base is spliced by left fitting seat and right fitting seat.Installation and maintenance are convenient in such design.
As preferably, worm screw input end stretches out from outer casing ends, and described outer casing ends is removably connected by connecting bolt and motor flange; Described connecting bolt is that ring is symmetrical.Frame can rotate arbitrarily within the specific limits, to adapt to the random adjustment of mounting point.
Advantage of the present utility model and beneficial effect are: speed reducer described in the utility model improves transmission accuracy and bearing capacity and working life by using planar double-enveloping worm, simultaneously by output shaft and worm gear integrally casting, obtain comparatively compact structure.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As Figure 1-Figure 2, a kind of worm reduction gear, comprises worm gear 1 and the worm screw 2 of the transmission that cooperatively interacts, and described worm gear 1 and worm screw 2 outer installment have the frame coordinated with worm gear 1 and worm screw 2; Described worm screw 2 is provided with worm screw 2 driving cog coordinated with worm gear 1, and described worm screw 2 driving cog is arranged on a plane-generated double enveloping anchor ring 3, and described worm gear 1 is provided with worm gear 1 driving cog, and described worm screw 2 driving cog engages with worm gear 1 driving cog; Described worm gear 1 center is provided with output shaft 4, and described output shaft 4 is shaping by spheroidal graphite cast iron integrally casting with worm gear 1; Described worm screw 2 is connected with drive motor by coupling.
The arc ring concave surface that described plane-generated double enveloping anchor ring 3 is thinner in thicker center, two ends.
Described frame is spliced by left shell 5 and right shell body 6, and described frame lower end is provided with base, and described base is spliced by left fitting seat 7 and right fitting seat 8.
Worm screw 2 input end stretches out from outer casing ends, and described outer casing ends is removably connected by connecting bolt 9 and motor flange 10; Described connecting bolt 9 is symmetrical in ring.
During use, by the connecting bolt 9 on frame, frame is connected with motor flange 10, the angle of frame can be adjusted as required, motor output shaft 4 is connected with worm screw 2 input end by coupling, then worm screw 2 is by plane-generated double enveloping anchor ring 3 and worm gear 1 transmission, such kind of drive formation basic theory Percent of contact area is high, and transmission accuracy is high; Worm screw 2 is multiple tooth contact with the engagement of worm gear, the instantaneous doublet contact in per tooth position, and circular tooth contact can reach more than 70%; The synthetic curvature of Surface of action is large; Line of contact is large in relative velocity angular separation, dynamic pressure oil film formed and retentivity good; Bearing capacity is large, and transmission efficiency is high, wear-resistant, can be widely used in the various industry kinds such as metallurgy, mine, chemical industry, building, rubber and plastic, boats and ships; Worm gear 1 and output shaft 4 integrally casting, and adopt the spheroidal graphite cast iron of high strength to cast to form, so both can save material and in turn save processing cost and also make the compact structure of product simple.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
