Description
Technical field
The present invention relates to a kind of mechanical transmission, particularly relate to a kind of floating gear train.
Background technique
Being used for mechanically operated train at present is divided three classes altogether according to the sorting technique of current textbook: fixed shaft gear train, epicyclic gear train and the compound gear train that is combined by fixed shaft gear train and epicyclic gear train.Although these three kinds of train structures are different, a common characteristic being arranged aspect transmission---the input end of motion and the relative position of output terminal are constant.Often running into input end and output terminal relative position in mechanical transmission is situation about changing, and in the prior art, mainly adopts Hooks coupling universal coupling or similar techniques to solve, and does not also adopt the solution of train at present.Because wheel ties up to transmission campaign aspect and has compact structure, be necessary to study a kind of wheel train structure that transmitting movement under the situation that relative position changes can be arranged at input end and output terminal.
Summary of the invention
Technical problem to be solved by this invention provide a kind of simple in structure, can realize that motion input end and output terminal have the floating gear train of the situation underdrive that relative position changes.
For achieving the above object, the present invention adopts technological scheme as described below:
A kind of floating gear train structure comprises gear shaft a, gear shaft b, gear shaft c; The pitch wheel axle a, the gear shaft b that are installed on the connecting plate a form transmission system I, and the pitch wheel axle b, the gear shaft c that are installed on the connecting plate b form transmission system II; The connecting plate a of transmission system I is that rotating shaft forms different angles with gear shaft b all with the connecting plate b of transmission system II, and gear shaft a realizes different centre distance with gear shaft c.
Described floating gear train structure, described gear shaft a by be sleeved on the corresponding shaft part Bearing Installation on one group of bearing hole of connecting plate a, described gear shaft b by be sleeved on the corresponding shaft part Bearing Installation connecting plate a another the group bearing hole on, diaxon cogs to be meshed and forms transmission system I, and the centre distance of two groups of bearing holes of connecting plate a equals the meshed center distance of gear shaft a and gear shaft b.
Described floating gear train structure, described gear shaft b is by being sleeved on Bearing Installation on the corresponding shaft part on one group of bearing hole of connecting plate b, described gear shaft c by be sleeved on the corresponding shaft part Bearing Installation connecting plate b another the group bearing hole on, diaxon cogs to be meshed and forms transmission system II, and the centre distance of two groups of bearing holes of connecting plate b equals the meshed center distance of gear shaft c and gear shaft b.
Described floating gear train, the axle head of described gear shaft a, gear shaft c is processed with keyway.
Because adopt aforesaid technological scheme, the present invention has following superiority:
1), transmission adopted gear structure, simple in structure, processing cost is low, stable drive.
2), connecting plate a is that rotating shaft forms different angles with connecting plate b with gear shaft b, allow gear shaft a to realize different centre distance with gear shaft c, promptly realized the change in location that input end and output terminal are bigger, compare with the Hooks coupling universal coupling that can realize similar functions, its axial dimension is less, has reduced the space that equipment occupies.
Description of drawings

Fig. 2 is the A-A sectional view of Fig. 1;
Among the figure: 1-connecting plate a; 2-connecting plate b; 3-gear shaft a; 4-gear shaft b; 5-gear shaft c; The 6-bearing; The 7-end cap; 8-covers thoroughly; The 9-jump ring.
Embodiment
Below in conjunction with accompanying drawing the present invention is explained further, it should be noted that the present invention is not limited to following embodiment, disclose purpose of the present invention and be intended to protect all changes and improvements in the scope of the invention.
Among Fig. 2, gear shaft a3, gear shaft b4 and gear shaft c5 are gear in the middle of all being, two ends are the symplex structure of multidiameter shaft, specifically are set to: two bearing positions of symmetrical distribution, gear shaft a3 two ends, four bearing positions of symmetrical distribution, gear shaft b4 two ends, two bearing positions of symmetrical distribution, gear shaft c5 two ends.Bearing 8 adopts with jump ring 9 positioning bearing inner rings and realizes the location of bearing on gear shaft after being set on the bearing position of gear shaft a3, gear shaft b4 and gear shaft c5 respectively.
Gear shaft a3 is installed on one group of bearing hole of connecting plate a1, gear shaft b4 is installed on another group bearing hole of connecting plate a1, gear shaft a3, gear shaft b4 cog and are meshed, and the centre distance of two groups of bearing holes of connecting plate a1 equals the meshed center distance of gear shaft a3 and gear shaft b4.
Gear shaft b4 is installed on one group of bearing hole of connecting plate b2, gear shaft c5 is installed on another group bearing hole of connecting plate b2, gear shaft b4, gear shaft c5 cog and are meshed, and the centre distance of two groups of bearing holes of connecting plate b2 equals the meshed center distance of gear shaft b4 and gear shaft c5.
The bearing position of promptly realizing gear shaft a3 is corresponding with the inner bearing position of gear shaft b4, and the bearing position of gear shaft c5 is corresponding with the outer bearing position of gear shaft b4.
After three gear shafts are in place, cover 8 thoroughly and pass gear shaft a3 shaft part and connecting plate a1 and connect firmly and be used for positioning bearing 6 outer rings and realize the location of bearing 6 on connecting plate a1; Saturating lid 8 passes gear shaft b4 shaft part and connects firmly with connecting plate a1 and be used for the location of realization bearing 6 on connecting plate a1, positioning bearing 6 outer rings; Saturating lid 8 passes gear shaft c5 shaft part and connects firmly with connecting plate b2 and be used for the location of realization bearing 6 on connecting plate b2, positioning bearing 6 outer rings; End cap 7 connects firmly with connecting plate b2 and is used for the location of realization bearing 6 on connecting plate b2, positioning bearing 6 outer rings.
As shown in Figure 1, connecting plate a1 and connecting plate b2 are rotating shaft with gear shaft b4 all, can form different angles, thereby realize that gear shaft a3 and gear shaft c5 centre distance change, but because connecting plate a1 and connecting plate b2 restriction, the centre distance of gear shaft a3 and gear shaft b4 is constant all the time, and the centre distance of gear shaft b4 and gear shaft c5 is constant all the time, does not influence drive connection.When with gear shaft c5 as the motion input end, with gear shaft a3 as the motion output terminal, gear shaft c5 always can transmit motion to gear shaft a3 by intermediate gear shaft b4.The axle head processing keyway of gear shaft a3 and gear shaft c5, gear shaft can connect moving element by coupling.
