Description
[technical field]
The present invention relates to transmission art field, especially relate to a kind of device for revolving and driving that is applicable to, and adopt the enveloping worm drive pair of planar double enveloping worm and Divergent exhaust pipes mating engagement.
[background technique]
Known, traditional device for revolving and driving is the mechanical transmission that slewing bearing and cylindrical gearing pair or cylindrical worm gearing transmission pair are combined to form, under normal circumstances, the outer ring of slewing bearing is cylindrical gears or worm gear, and with it corresponding matching be cylindrical gears or cylindrical worm; Because the device for revolving and driving with big speed ratio often all adopts worm drive, namely single staged transmission ratio can reach 10-200, and therefore its application is comparatively extensive; But, the worm gears of current routine application but also exists following defect: 1, not only efficiency is low, power consumption is large in worm gear pair transmission, and it is higher to lubricating requirement, due to worm and wheel long-term work on one face, therefore pressure is larger, be difficult to produce lubricant film, thus cause it very easily to wear and tear; 2, the conventional worm gear matched with worm screw cannot realize roll flute and processes, cause its bulk strength lower because its tooth face hardness is low, simultaneously, worm screw is difficult to carry out high fine ginding to the flank of tooth in manufacture with processing, and therefore its flank of tooth is also difficult to produce high hardness, as improved its hardness by integral quenching, then worm screw distortion is larger, and then its precision cannot be guaranteed, cause worm gear in use stressed suddenly indiscreet and negligent heavy, extremely uneven; 3, in order to improve the wear resistance of worm gear, the material now for the manufacture of worm gear chooses cast tin bronze usually, expensive due to tin bronze, and the overall cost that thus result in worm gears is higher, and user cost remains high; 4, the outer ring of slewing bearing and bronze worm gear use after needing to assemble, and due to its complex process, therefore very easily produce alignment error; In sum, because worm drive conventional now has more and more been difficult to meet the usage requirement of Large-torsion transmisson, therefore, a kind of device for revolving and driving that can be used in transmitting large torque has just been badly in need of in the market.
[summary of the invention]
In order to overcome the deficiency in background technique, the invention discloses a kind of enveloping worm drive secondary, described transmission can realize larger velocity ratio, therefore, it is possible to be applicable to the revolution transmission of high pulling torque.
For achieving the above object, the present invention adopts following technological scheme:
A kind of enveloping worm drive is secondary, and described transmission comprises housing, end cap, drive motor, planar double enveloping worm and Divergent exhaust pipes; Be provided with in described housing and located by end cap, and the planar double enveloping worm driven by drive motor, this planar double enveloping worm and the Divergent exhaust pipes engagement driving being fixedly placed on slewing bearing inner ring outside; The angle of lead of described planar double enveloping worm is identical with the helix angle size of Divergent exhaust pipes, and Hand of spiral is identical; The ratio of described planar double enveloping worm and the addendum of Divergent exhaust pipes and dedendum of the tooth is set to 0.8 ︰ 1, and the tooth logarithm that planar double enveloping worm and Divergent exhaust pipes engage simultaneously is 4 ~ 7 right.
Described enveloping worm drive is secondary, is symmetrically installed with the planar double enveloping worm of two synchronous and Divergent exhaust pipes engagement driving in described housing.
Described enveloping worm drive is secondary, and after described planar double enveloping worm and Divergent exhaust pipes are all hardened by teeth portion, roll flute processes.
Described enveloping worm drive is secondary, and described Divergent exhaust pipes is made up of Bearing Steel.
Owing to adopting technological scheme as above, the present invention has following beneficial effect:
Enveloping worm drive of the present invention pair have employed the structure that planar double enveloping worm and Divergent exhaust pipes match, wherein, the flank of tooth of toroid helicoids worm forms through flat-faced wheel grinding, helical gear is then common cylinder involute helical gear, namely worm screw and helical gear all can realize roll flute processing, this not only effectively can remove the heat treatment deformation of the flank of tooth, but also effectively can improve tooth accuracy; Meanwhile, because described transmission adopts Divergent exhaust pipes as the outer ring of slewing bearing, it adopts again Bearing Steel manufacture to form, therefore compared with tin bronze, its not only cost significantly reduce, and structure is more compact; In addition, because the flank engagement between the worm screw in described transmission and helical gear is mismatch point cantact, therefore it is insensitive to alignment error, not high to the required precision of profile of tooth, namely conventional worm gear pair is compared, described transmission is not only easier to installation and maintenance, and due to two flank of tooth adopt 4 ~ 7 multiple tooth right while engagement, therefore the intensity of its face and the bending intensity of tooth root all effectively improve; In sum, described transmission bearing capacity is strong and intensity is higher, and it reaches the object of the heavy duty revolution transmission being applicable to transmitting large torque by realizing larger velocity ratio.

In figure: 1, housing; 2, end cap; 3, drive motor; 4, planar double enveloping worm; 5, Divergent exhaust pipes; 6, slewing bearing inner ring.
[embodiment]
Can explain the present invention in more detail by the following examples, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:
Enveloping worm drive by reference to the accompanying drawings described in 1 is secondary, and described transmission comprises housing 1, end cap 2, drive motor 3, planar double enveloping worm 4 and Divergent exhaust pipes 5; Be provided with in described housing 1 and located by end cap 2, and the planar double enveloping worm 4 driven by drive motor 3, this planar double enveloping worm 4 and Divergent exhaust pipes 5 engagement driving being fixedly placed on slewing bearing inner ring 6 outside, namely described transmission have employed the Divergent exhaust pipes 5 be made up of the Bearing Steel outer ring as slewing bearing, therefore not only save cost, but also effectively raise integrally-built compactedness; As required, can in housing 1 symmetrical install two with the planar double enveloping worm 4 of Divergent exhaust pipes 5 engagement driving, thus reach the object utilizing the planar double enveloping worm 4 of these two synchronous axial system effectively to increase described transmission bearing capacity;
When designing physical dimension and the processing flank of tooth, must ensure that the angle of lead of planar double enveloping worm 4 is identical with the helix angle size of Divergent exhaust pipes 5, and Hand of spiral be identical, thus effectively can guarantee both correct engagement; In addition, after described planar double enveloping worm 4 and Divergent exhaust pipes 5 are all hardened by teeth portion, roll flute processes, namely planar double enveloping worm 4 and Divergent exhaust pipes 5 all can realize roll flute processing, thus effectively raise both tooth accuracy, and then described transmission is made to reach the object of the roll flute processing that common worm drive cannot realize; Between planar double enveloping worm 4 and Divergent exhaust pipes 5, there is good flank engagement district in order to ensure, planar double enveloping worm 4 and the addendum of Divergent exhaust pipes 5 and the ratio of dedendum of the tooth can be set to 0.8 ︰ 1, thus effectively ensure that the tooth logarithm simultaneously engaged can reach 4 ~ 7 right between the two, and then the bearing capacity of described transmission is made to improve 3 ~ 5 times than common worm drive.
Part not in the detailed description of the invention is prior art, therefore the present invention is not described in detail.
