Abstract
The utility model discloses a kind of improvement splined shaft, belong to mechanical field, it is characterized in that: said splined shaft (a) is one section of hollow cylindrical body, on its cylndrical surface, corresponding position is provided with arcuate groove (1); The cylindrical raceway of the inner side of spline mother (b) wherein, forms the domestic and foreign work guide rail of ball with the arcuate groove (1) of splined shaft (a).Cylndrical surface is provided with tooth bar (2), realizes straight line motion with gears meshing simultaneously, eliminates in the past additional gear (synchronous pulley) and coordinates with tooth bar (Timing Belt) and make splined shaft realize straight line motion.The overall weight of splined shaft is very light, and motional inertia is very little, is particularly suitable for the performance requirement of modern comfort high speed degree, high sensitivity, high reliability.
Description
Technical field
The utility model relates to a kind of improvement splined shaft, belong to mechanical field, a kind ofly specifically improves on original splined shaft basis, be usually used in automation equipment and other have high sensitivity high reliability straight line motion and in the system of transmitting torque.The frame of such as industrial robot is lived and mechanical arm, automatic loader and unloader, conveyer, automatic conveying device, tyre building machine, spot welding machine main shaft, the High-Speed Automatic application axis of guide, riveting machine, winding machine, discharging processing machine head, lapping machine main shaft drives axle, various speed change gear, precision scale division axis etc.
Background technique
Well-known in machinery, the device of transmitting torque in straight line motion is needed to need to use spline pair, but often in order to realize the mode of structure that straight line motion adopts gear (synchronous pulley) to coordinate tooth bar (Timing Belt) to install separately, such apparatus structure is complicated and cost is higher.
Model utility content
In the utility model, a kind of improvement spline pair mainly solves existing technical problem deficiency, the mode of structure of one is designed to by splined shaft and tooth bar, or the structural type of complexed metal or nonmetal tooth bar on splined shaft, the motor eliminated in the past drives independent gear (synchronous pulley) to coordinate independent installation of tooth bar (Timing Belt) to drive spline pair to realize the straight line motion of moving element.
Splined shaft (a) is steel cylinder, and its periphery is uniform-distribution with the adjacent manufacturing gear strip (2) of the recessed Gothicism raceway (1) be made up of bicircular arcs of more than at least 1 the recessed bicircular arcs on periphery; Or square groove (g) offered by splined shaft (a), tooth bar (f) is fixed in square groove (g), splined shaft (a) coordinates with spline mother (b), and spline mother (b) is fixed on casing (F), gear (K) is fixed on motor shaft, and engage with the tooth bar on splined shaft, realize the linear movement of parts.
The motional inertia of light spline pair is also less, installs and also does relative light and handy with the parts of carry-over moment,
Namely the weight of whole moving element and inertia all less, reach same design speed, required power consumption is also much smaller, and the device of transferring power also can be more very thin, and whole weight of equipment is reduced greatly.
In sum, the utility model has the features such as low cost, low-frictional force, low inertia.The equipment using the utility model to make has low cost, low energy consumption especially, take up room the characteristic such as little.
Accompanying drawing explanation
Fig. 1 is overall structure stereogram of the present utility model.
Fig. 2 is the scheme of installation of the utility model on equipment.
Fig. 3 is another kind of structural representation of the present utility model.
Fig. 4 is the another kind of texture edge view of splined shaft.
In figure (1) for raceway (2) for tooth bar (a) for splined shaft (b) for spline mother (K) for gear (F) for casing (f) for metal or nonmetal tooth bar (g) they are square groove.
Embodiment
Splined shaft (a) is steel cylinder, its periphery is uniform-distribution with the adjacent manufacturing gear strip (2) of the recessed Gothicism raceway (1) be made up of bicircular arcs of more than at least 1 the recessed bicircular arcs on periphery, or square groove (g) offered by splined shaft (a), tooth bar (f) is fixed in square groove (g), splined shaft (a) coordinates with spline mother (b), and spline mother (b) is fixed on casing (F), motor is fixed on casing (F), gear (K) is fixed on motor shaft, and engage with the tooth bar on splined shaft, realize the straight line motion of parts.
