Abstract
The utility model relates to a gear with function for removing the backlash of a gear pair, which is characterized in that the gear comprises a main gear (1) and an auxiliary gear (3) which are fastened with each other. The fastened faces of the main and auxiliary gears are respectively provided with ring grooves which form a ring cavity in which a torsion spring (2) is arranged, and both ends of the torsion spring (2) are respectively combined with the main and auxiliary gears. The gear of the utility model can cause the tooth surface of the gear and the tooth surface of the gear engaged with the gear of the utility model to be always in backlash-less operating and engaging state under the pre-tightening force action of the torsion spring, which fundamentally solves the transmitting backlash problem of the gear pair and realizes the backlash-less transmission of the gear pair.
Description
(1) technical field
The utility model relates to a kind of gear that is applicable in little load gear auxiliary driving and the manual gear transmission regulating mechanism, relates to a kind of gear of eliminating the gear-pair backlash function that has specifically.
(2) background technique
In gear drive, each is to all existing certain gear-pair backlash between the pitch wheel.Because the existence of this sideshake in the actual transmission process, spacious position phenomenon particularly very easily occurs between the gear pair of frequent clockwise and anticlockwise running, its result not only can cause noise and vibratory output to increase, and also can have influence on the precision of gear transmission regulating mechanism.For addressing the above problem, mostly prior art is to reach the purpose that reduces sideshake from the accuracy of manufacturing that improves gear, but this way has also directly increased the manufacture cost of gear.
(3) summary of the invention
The purpose of this utility model provide at existing problem in the above-mentioned prior art just a kind of scientific and reasonable for structure, manufacture cost is lower and can keep the gear of eliminating the gear-pair backlash function that has of gear pair zero sideshake running automatically.
The purpose of this utility model can realize by following measure:
Gear with elimination gear-pair backlash function of the present utility model comprises the master gear and the pinion of mutual fastening, be provided with torque spring in the toroidal cavity that is made of the annular groove that processes respectively on the major and minor gear buckling surface, the two ends of described torque spring combine with major and minor gear respectively.
Torque spring described in the utility model is an open annular structure, and the attachment hole that the two ends of trip ring process on the extension pin that constitutes of the extension of extending to both sides of the symmetry by being arranged on its end and the major and minor gear sidewall respectively combines.Certain described torque spring also can adopt the structural type of other any known to realize: as spiral torsion spring etc.
Concrete fit of the present utility model and working principle are as follows:
During assembling torque spring is placed in the toroidal cavity of the annular groove formation that processes respectively on the major and minor gear buckling surface, the attachment hole that processes on extension pin by being arranged on the torque spring two ends and the major and minor gear sidewall combines, and major and minor gear is fastened mutually, again pinion is rotated several teeth along the direction of torque spring power, the gear mass and another Gear combination that will form after will being fastened by major and minor gear afterwards get final product.Gear of the present utility model is under the effect of torque spring pretightening force, can make its flank of tooth with and the flank of tooth of its gear that is meshed between be in no sideshake running engagement all the time, this has also just fundamentally solved the sideshake problem in the gear pair transmission, and the zero sideshake transmission of gear pair is become a reality.
(4) description of drawings
Fig. 1 is a three-dimensional structure diagram of the present utility model.
Fig. 2 is the phase diagram that is used in combination of the present utility model.
Part 1 is a master gear among the figure, and part 2 is torque springs, and part 3 is pinion (part 1,2,3 common formation driving gears), and part 4 is driven gears.
(5) embodiment
The utility model is further described below with reference to embodiment's (accompanying drawing):
As shown in Figure 1, gear with elimination gear-pair backlash function of the present utility model comprises the master gear 1 and the pinion 3 of mutual fastening, be provided with torque spring 2 in the toroidal cavity that constitutes by the annular groove that processes respectively on the major and minor gear buckling surface, described torque spring 2 is an open annular structure, and the attachment hole that the two ends of trip ring process on the extension pin that constitutes of the extension of extending to both sides of the symmetry by being arranged on its end and the major and minor gear sidewall respectively combines.Gear of the present utility model uses mainly as driving gear, also can be used as third wheel and uses.Phase diagram when Fig. 1,2 has only provided and used as driving gear, the phase diagram when promptly constituting driving gear jointly and be meshed with driven gear 4 by master gear 1, torque spring 2, pinion 3.
Claims (2)
1, a kind of gear with elimination gear-pair backlash function, it is characterized in that: it comprises the master gear (1) and the pinion (3) of mutual fastening, be provided with torque spring (2) in the toroidal cavity that is made of the annular groove that processes respectively on the major and minor gear buckling surface, the two ends of described torque spring (2) combine with major and minor gear respectively.
2, the gear with elimination gear-pair backlash function according to claim 1, it is characterized in that: described torque spring (2) is for open annular structure, and the attachment hole that processes on the extension pin that the extension that extend to both sides by the symmetry that is arranged on its end respectively at the two ends of trip ring constitutes and the major and minor gear sidewall combines.
