Abstract
Provided is a gapless worm and gear speed reducer for an industrial pipe mechanical device. The speed reducer comprises a box body, a first output shaft pivoted in the box body and one end of which penetrates from the box body, a worm pivoted in the box body, and a worm gear synchronously connected on the first output shaft and engaged with the worm. The worm gear and the worm are double-lead worm and gear, the box body is fixed with two output end covers provided at two ends of the first output shaft, and the box body is also fixed with two input end covers provided at two ends of the worm. Compared with the prior art, the double-lead worm and gear is employed, after the worm and gear is wore and a gap appears, an engagement gap between the worm and the worm gear can be adjusted along the axial direction of the worm so that the transmission error is reduced and the transmission precision is guaranteed. Meanwhile, double-shaft output can be achieved, by the transmission of a gear, the output torque is increased, and multi-shaft linkage is realized.
Description
Technical field
The utility model relates to the gapless worm-gear speed reducer of a kind of industry pipe machinery.
Background technique
In industry pipe course of working, usually the rotating spindle that industry need be managed process equipment is connected on the speed reducer, utilize speed reducer that the rotational velocity of machine shaft is adjusted to the speed of machine spindle proper functioning, make the main shaft of equipment obtain bigger moment of torsion simultaneously.
Most speed reducer normally adopts gear as the parts of transmission, realize the purpose of slowing down in the mode of multistage transmission, but these is higher as the wear rate of the speed reducer of transmission part with gear.In industry pipe course of working; usually can adopt the speed reducer of the worm and gear kind of drive; its compact structure, velocity ratio are big; and has auto-lock function under certain condition; but; because worm and gear after wearing and tearing, can increase the back lash of worm gear and worm screw, is unfavorable for mechanical circular movement precision drive.
The model utility content
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of industry pipe machinery gapless worm-gear speed reducer, it can adjust the back lash of worm gear and worm screw after worm gear and worm screw wearing and tearing, improve the precision of mechanical circular movement.
For achieving the above object, the utility model adopts following technological scheme:
The gapless worm-gear speed reducer of industry pipe machinery, comprise casing, be articulated in the casing and first output shaft that an end is passed by casing, be articulated in worm screw in the casing, synchronously be connected on first output shaft and with the worm gear of worm meshing, worm gear and worm screw are two helical pitch worm and gears, two output end caps that are positioned at the first output shaft two ends are fixedly arranged on the casing, two input end caps that are positioned at the worm screw two ends are fixedly arranged on the casing.
Worm screw and first output shaft all by bearing hinge joint in casing.
Also be articulated with one second output shaft in the casing, this second output shaft and second output shaft parallel with first output shaft connects synchronously with first output shaft.
Be connected with one first driving gear on first output shaft synchronously, be connected with second driving gear of one and first driving gear engagement on second output shaft synchronously.
First driving gear is identical with the diameter of second driving gear.
The beneficial effects of the utility model are:
Than prior art, the utility model adopts the worm and gear of two helical pitches, after the worm and gear wearing and tearing produce the gap, can in order to reduce driving error, guarantee the precision of transmission along the back lash of the axial adjustment worm and wheel of worm screw.Simultaneously, can realize twin shaft output, by gear transmission, output torque strengthens, and realizes multi-shaft interlocked.

Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, 2, be the gapless worm-gear speed reducer of a kind of industry pipe machinery of the utility model, it comprises casing 10, be articulated in the casing 10 and first output shaft 20 that an end is passed by casing 10, be articulated in worm screw 40 in the casing 10, synchronously be connected on first output shaft 20 and with the worm gear 30 of worm screw 40 engagements, worm gear 30 and the two helical pitch worm and gears of worm screw 40 for working in coordination, two output end caps 11 that are positioned at first output shaft, 20 two ends are fixedly arranged on the casing 10, two input end caps 12 that are positioned at worm screw 40 two ends are fixedly arranged on the casing 10.Worm screw 40 and first output shaft 20 all by bearing hinge joint in casing 10.
Because above-mentioned worm gear 30 adopts two worm and gears of leading into worm screw 40, after worm gear 30 and worm screw 40 uses the long periods to wear and tear, can be along the axial adjustment worm screw 30 of worm screw 40 and the distance of worm gear 40, thus the back lash of worm gear 30 and worm screw 40 changed, guarantee the validity of transmission.
Referring to Fig. 3, the gapless worm-gear speed reducer of another kind of industry pipe machinery of the present utility model, it is on the basis of such scheme, in casing 10, be articulated with one second output shaft 50, this second output shaft 50 is parallel with first output shaft 20, its the two certain distance that staggers mutually, be connected with one second driving gear 51 on second output shaft 50 synchronously, be connected with one first driving gear 21 on first output shaft 20 synchronously, first driving gear 21 connects synchronously with second driving gear 51, namely drives first output shaft 20 and 50 rotations of second output shaft simultaneously by worm screw 40.The first above-mentioned driving gear 21 is identical with the diameter of second driving gear 51, makes the output shaft 20 of winning identical with the rotating speed of second output shaft, 50 outputs.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection domain of the utility model claim all according to technological scheme described above and design.
