Description
technical field:
The present invention relates to a kind of gear pair that prevents from clashing into and guaranteeing centre distance.
background technique:
Conventional gear engagement at present is mainly divided into following two kinds of situations: the first situation is that gear engages surely, and the central shaft of two gears is on a pedestal, guarantees centre distance (as Fig. 1) by machining accuracy.The second situation is the moving engagement of gear, the central shaft of two gears is respectively on different pedestals, gear 1 is arranged on pedestal 2, gear 4 is arranged on pedestal 3, pedestal 3 is close to it with pedestal 2 benchmark, arrive theoretical center behind position, utilize the positioning parts of screw or buckle and so on, guarantee that by pedestal machining accuracy and assembling Gear center is apart from (as Fig. 2).These two kinds of situations have the defect of oneself, and the first situation need to guarantee the machining accuracy of gear and pedestal simultaneously, if there is side's machining accuracy can not guarantee just may not guarantee centre distance.In second, situation requires highlyer, and not only need to guarantee the machining accuracy of gear and pedestal also will have rational assembly technology simultaneously, guarantees assembly precision, also may occur that in addition gear clashes into injured situation in assembly process.
summary of the invention:
The object of this invention is to provide a kind of in the situation that of the moving engagement of gear low cost guarantee Gear center apart from and prevent from clashing between gear the gear pair of the noise while subtracting pinion rotation.
The present invention is achieved in that
The 1st gear 4 is arranged on slide teeth wheel shaft 6, the 2nd gear 1 is arranged on fixed gear shaft 7, slide teeth wheel shaft 6 moves and coordinates with the groove 3a on the 1st pedestal 3, slide teeth wheel shaft 6 is arranged on the 1st pedestal 3, fixed gear shaft 7 is arranged on the 2nd pedestal 2, the 2nd pedestal 2 and the 1st pedestal 3 positions are fixed, gear holds out against spring 5 one end and is connected with the 1st pedestal 3 groove 3a, the other end holds out against slide teeth wheel shaft 6, the 1st gear 4 holds out against spring 5 pretightening forces with the 2nd gear 1 by gear and engages, when engagement, the 1st cylinder 4a that equals the 1st gear compound graduation circular diameter that the 2nd cylinder 1a that equals the 2nd gear compound graduation circular diameter that the 2nd gear 1 side connects is connected with the 1st gear 4 sides contacts.
Advantage of the present invention is: 1. can, in the time of moving engagement between gear, prevent that the shock between gear from causing gear destruction, particularly the moving meshed gears pair regular to needs, has great protective action.2. the centre distance that can low cost guarantees gear, is farthest guaranteed the centre distance between gear.3. because the engagement between gear is flexible cooperation, so the noise can subtract pinion rotation time.

Embodiment
The 1st gear 4 is arranged on slide teeth wheel shaft 6, the 2nd gear 1 is arranged on fixed gear shaft 7, slide teeth wheel shaft 6 moves and coordinates with the groove 3a on the 1st pedestal 3, slide teeth wheel shaft 6 is arranged on the 1st pedestal 3, fixed gear shaft 7 is arranged on the 2nd pedestal 2, the 2nd pedestal 2 and the 1st pedestal 3 positions are fixed, gear holds out against spring 5 one end and is connected with the 1st pedestal 3 groove 3a, the other end holds out against slide teeth wheel shaft 6, the 1st gear 4 holds out against spring 5 pretightening forces with the 2nd gear 1 by gear and engages, when engagement, the 1st cylinder 4a that equals the 1st gear compound graduation circular diameter that the 2nd cylinder 1a that equals the 2nd gear compound graduation circular diameter that the 2nd gear 1 side connects is connected with the 1st gear 4 sides contacts.
Below in conjunction with accompanying drawing, describe technological scheme of the present invention in detail:
As shown in Figure 3 and Figure 4, gear 1 side is with a cylinder 1a who equals gear compound graduation circular diameter, and gear 4 is with gear 1, same in side with a cylinder 4a who equals gear compound graduation circular diameter.
As shown in Figure 5, fixed gear shaft 7 is arranged on pedestal 2, and gear 1 is arranged on fixed gear shaft 7.On pedestal 3, have a groove 3a, gear 4 is arranged on slide teeth wheel shaft 6, and slide teeth wheel shaft 6 is arranged on pedestal 3, and can slidably reciprocate along groove 3a direction.Gear holds out against spring 5 and can be arranged in groove 3a, and holds out against slide teeth wheel shaft 6, and this is just equivalent to gear and holds out against spring 5 and held out against gear 4, makes gear 4 have the pretightening force of a direction.Pedestal 3 is close to pedestal 2, when engaging gear.Because there is gear to hold out against spring 5, so in the moment of engagement, gear 1 can make gear 4 retreat with the shock that gear 4 produces, and holds out against spring 5 by gear and absorb and clash into the energy producing.Subsequently, pedestal 3 reach design attitude fixing after because gear holds out against the pretightening force of spring 5, can make gear 4 closely engage with gear 1, guarantee that gear 4 can processed precision not affect with assembly precision while engaging with gear 1, can never occur that operating center distance distance is greater than the situation of theoretical center distance.
As shown in Figure 6, when gear 4 and gear 1 engage, because holding out against spring 5, gear gear has pretightening force, to make gear 4 close to gear 1 central direction, during this time, the cylinder 1a that equals gear compound graduation circular diameter of gear 1 side band and gear 4 with the cylinder 4a that equals gear compound graduation circular diameter can contact, prevent that gear 1 and gear 4 are further close, guarantee when gear 1 engages with gear 4 to occur that operating center distance is less than the situation of theoretical center distance.
