Description
Technical field
The utility model is applied to the technical field of index dial, and espespecially it technically provides a kind of index dial drive mechanism.
Background technology
Worm gear and worm screw are the hinge of industrial quarters transmission, every various machinery and machine, the mutual matched combined of worm gear and worm screw is all depended on to form reception and registration, as in mechanical industry the various work mechanisms etc. such as conveyer, lift, crane commonly used, capital uses worm gear, the mutual matched combined of worm screw forms, even be that worm gear interval on worm screw is also convenient as functions such as altitude locations for amplifying drive motor strength, producing high-torque transporting articles.
Wherein, the index dial drive mechanism commonly used is of a great variety, is hereby exemplified below: known drive mechanism uses worm and gear group, and wherein comprise: a worm screw, this worm screw face establishes a screw thread; One worm gear, this worm-wheel shaft is to equidistantly establishing several driving cog, and when this worm screw is rotated, this screw thread is engaged with respectively this driving cog of this worm gear and transmits power; The structure of above, rotates a workbench, makes the workpiece on this workbench can change angle to process.
But still there is many problems in known index dial drive mechanism, wherein worm and gear group belongs to crossed-axes gear drive, and contact Tooth is slided large, and the abrasion of the flank of tooth are comparatively serious, once namely abrasion cause back clearance to increase, and then produce the error of division and make the minimizing of precise decreasing, overall structure rigidity low and torsion; And comparatively inaccuracy during transmission, easily produce the problems such as vibration.
Therefore for the problem points existing for above-mentioned known drive mechanism, how to develop a kind of innovation structure having more desirable practicality, in fact for consumer eagerly looks forward to, be also target and the direction that relevant dealer must make great efforts research and development breakthrough.
Utility model content
For the problem points existing for above-mentioned conventional construction, the purpose of this utility model is to provide a kind of index dial drive mechanism, and its structure is simple, effectively can improve precision, increases integral rigidity, can also improve the torsion of transmission in addition.
For achieving the above object, the utility model discloses a kind of index dial drive mechanism, it is characterized in that comprising: a body, a workbench, a rotary main shaft and a driving shaft; This rotary main shaft establishes a main shaft bearing and one end is fixedly arranged on this workbench, and establishes this driving shaft to carry out this rotary main shaft of vertical-transmission in this body, it is characterized in that:
The solid circular row of this rotary main shaft radial surface spiral shell below this main shaft bearing shows several roller;
This driving shaft establishes a curve cambered surface, and this curve cambered surface establishes a curved-line thread against each this roller, and this curved-line thread embeds respectively between this roller.
Wherein, this driving shaft respectively establishes a bearing in axial two ends.
Wherein, this driving shaft one end is hubbed at this body, and installs an oil seal cover in this body.
By this, the curved-line thread of driving shaft of the present utility model closely embeds respectively between this roller, and this curve cambered surface is also close to respectively this roller; When this driving shaft is through when respectively this roller transmits power to this rotary main shaft, the back clearance produced that reduces wear improves precision, increases drive mechanism integral rigidity simultaneously; In addition the torsion transmitted significantly promotes.
About technology, means and effect thereof that the utility model adopts; hereby lift a preferred embodiment and after coordinating graphic and figure number to be described in more detail in; your juror phase can make have more detailed understanding to the utility model; and make to be familiar with this operator and can implement according to this; the following stated person is only explain preferred embodiment but not be to limit scope of the present utility model; therefore allly have based on spirit of the present utility model; and be any type of change of structure of the present utility model or modification, all should belong to the category of the utility model intention protection.

Detailed description of the invention
Refer to shown in Fig. 1 to Fig. 5, the utility model embodiment provides a kind of index dial drive mechanism, comprises: body 10, workbench 20, rotary main shaft 30 and a driving shaft 40; This rotary main shaft 30 establishes a main shaft bearing 21 and one end sets firmly this workbench 20, and this rotary main shaft 30 loads by above this body 10; And in this body 10, establish this driving shaft 40 to carry out this rotary main shaft 30 of vertical-transmission, it is characterized in that:
The solid circular row columns roller 31 of this rotary main shaft 30 radial surface spiral shell below this main shaft bearing 21; This driving shaft 40 establishes a curve cambered surface 41, and this curve cambered surface 41 establishes a curved-line thread 42 against each this roller 31, and this curved-line thread 42 embeds respectively between this roller 31.
Wherein, this driving shaft 40 respectively establishes a bearing 43 in axial two ends.
Wherein, this driving shaft 40 one end is hubbed at this body 10, and installs an oil seal cover 50 in this body 10.
During operation, driven by a power source (not shown) and rotate this driving shaft 40, this curved-line thread 42 via this curve cambered surface 41 rotates, to drive respectively this roller 31; Rotating via this rotary main shaft 30 allows this workbench 20 change angle to carry out the processing of different angles to rotate to adjust again; In addition, due to above-mentioned structure, this curved-line thread 42 of this driving shaft 40 is closely embedded respectively between this roller 31, and this curve cambered surface 41 is also close to respectively this roller 31 in addition; When this driving shaft 40 is through when respectively this roller 31 transmits power to this rotary main shaft 30, the back clearance produced that reduces wear improves precision, and the torsion simultaneously increasing drive mechanism integral rigidity and transmission such as significantly to promote at the function.
Conclude above-mentioned explanation, by the design of the utility model said structure, effectively can overcome the disappearance that conventional construction faces, there is above-mentioned numerous advantage and practical value further, therefore the utility model is splendid novel of an intention, and in identical technical field, have no identical or approximate product creation or open use, therefore the utility model has met patent about " novelty " and the important document of " progressive ", is file an application in accordance with the law; Only, person skilled in the art scholar is when carrying out changing and revise to the utility model not departing under spirit of the present utility model and principle, and these changes and revising, and all should be covered by the category that following claim defines.
