Abstract
The utility model discloses a dual-lead worm and gear speed reducer. The dual-lead worm and gear speed reducer comprises a shell, a worm gear arranged in the shell, a worm and an output shaft, wherein the worm gear is perpendicular to and matched with the worm, the worm is fixedly sheathed on the output shaft, a mounting flange and an end closure are fixedly connected at the two ends of the shell, which correspond to the worm, and the tooth thickness of the worm gradually and uniformly increases from one end of the worm, which corresponds to the mounting flange, to the other end of the worm. The technical scheme of the dual-lead worm and gear speed reducer has the advantages of high transmission accuracy, indexing accuracy and positioning accuracy, and stronger reliability, and has a more economic and practical effect.
Description
Technical field
The utility model relates to a kind of pair of helical pitch worm-gear speed reducer.
Background technique
Traditional two helical pitch worm-gear speed reducers, generally include casing, be arranged on worm gear, worm screw and output shaft in the casing, described worm gear is the vertical setting that matches with worm screw, the worm gear fixed cover is located on the output shaft, the corresponding worm screw end positions of casing is fixedly connected with mounting flange and end cap, because the Surface of action of worm and gear has relative movement when work, can aggravate its wearing and tearing if eliminate the gap of the worm and gear flank of tooth fully, cause motion dumb, worm gear, worm screw are scrapped in advance; If excesssive gap can affect its transmission accuracy, indexing accuracy, Location accuracy again, need to change worm and gear.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of transmission accuracy, indexing accuracy, Location accuracy higher, and reliability is stronger, more economically, practical two helical pitch worm-gear speed reducers.
For achieving the above object, the utility model provides following technological scheme: a kind of pair of helical pitch worm-gear speed reducer, comprise casing, be arranged on worm gear, worm screw and output shaft in the casing, described worm gear is the vertical setting that matches with worm screw, the worm gear fixed cover is located on the output shaft, the corresponding worm screw end positions of casing is fixedly connected with mounting flange and end cap, and the transverse tooth thickness of described worm screw is gradually uniform thickened setting from the corresponding mounting flange end to end of worm screw.
The utility model further is set to: corresponding mounting flange one end of described worm screw is provided with the axis hole with the coaxial setting of worm screw, the worm screw correspondence is provided with axis hole one end, worm screw relatively is provided with and is provided with respectively bearing between the axis hole the other end and the casing, and the worm screw correspondence is provided with between axis hole one end and the mounting flange and also is folded with seal ring.
The utility model further is set to: be provided with oil sealing between described output shaft two ends periphery and the casing.
By adopting the technical program, if in use worm gear, worm screw are because wearing and tearing cause drive gap to increase, as long as at this moment adjust the axial position of worm screw, can make the Worm and Worm Gear Driving pair return to original precision, do not need the worm screw, the worm gear that more renew, very economical, practical, multiplex in precision drive.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the utility model example structure figure;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, disclosed pair of helical pitch worm-gear speed reducer of the utility model, comprise casing 1, be arranged on worm gear 2, the worm screw 3 and output shaft 4 of establishing in the casing 1, described worm gear 2 is the vertical setting that matches with worm screw 3, worm gear 2 fixed covers are located on the output shaft 4, casing 1 corresponding worm screw 3 end positions are fixedly connected with mounting flange 5 and end cap 6, and the transverse tooth thickness of described worm screw 3 is gradually uniform thickened setting from worm screw 3 corresponding mounting flange 5 end to end.Described worm screw 3 corresponding mounting flange 5 one ends are provided with the axis hole 301 with worm screw 3 coaxial settings, worm screw 3 correspondences are provided with axis hole 301 1 ends, worm screw 3 relatively is provided with between axis hole 301 the other ends and the casing 1 and is provided with respectively bearing 7, and worm screw 3 correspondences are provided with between axis hole 301 1 ends and the mounting flange 5 and also are folded with seal ring 9.Axis hole 301 can external input shaft.Be provided with oil sealing 8 between described output shaft 4 two ends peripheries and the casing 1.
By adopting the technical program, if in use worm gear 2, worm screw 3 are because wearing and tearing cause drive gap to increase, as long as at this moment adjust the axial position of worm screw 3, can make worm screw 3 worm gears 2 transmissions return to original precision, do not need the worm screw 3, the worm gear 2 that more renew, very economical, practical, multiplex in precision drive.
Above-described embodiment should not be considered as the restriction to the utility model technology, but any improvement of doing based on technical solutions of the utility model spirit, all should be within the utility model protection domain.
Claims (3)
