Description
Technical field
The invention belongs to the gear transmission technology field, relate to a kind of gear and all carry transmission device.
Background technique
In gear ordinary transmission system, for improving bearing capacity, existing structure adopts an input helical gear to mesh simultaneously with other three identical output helical gears, utilizes three output helical gears to share moment of torsion jointly, and will import helical gear by radial and float, make that respectively exporting helical gear can all carry.But in this structure, in the time of can producing axial force owing to the employing helical gear, so the working condition requirement height of bearing, damage of bearings rate height when heavy duty is used.
Summary of the invention
Technological scheme of the present invention is in order to overcome the shortcoming that the suffered axial force of bearing is big, the life-span is low that the helical gear that exists in the prior art causes, to propose a kind of gear and all carry transmission device, improve the bearing capacity of prior art, reducing radial dimension.
Technological scheme of the present invention:
A kind of gear all carries transmission device, power is by a primary input axle input, an input gear and this rigid joint, 3 output shafts are arranged, all be connected with 1 output gear on the every axle, these 3 output gears are identical and mesh simultaneously with the input gear, the geometrical axis fixed-site of 3 output shafts, and power is by the output of 3 output shafts; Gear and 3 output gears are herringbone tooth; And 3 output gears can axially be adjusted the fixing or axial free floating in back, but import the gear radial floating simultaneously, thereby make each output shaft in this gear drive all to carry.
Said gear can be internal gear, also can be external gear; Said herringbone tooth can be no groove herringbone tooth, also can be the with groove herringbone tooth; Can be integral structure, also can be the structure that the split manufacturing is linked together in any rigid joint mode afterwards; The both sides helix angle direction of said herringbone tooth is opposite, but the big I of helix angle is identical, also can be different, and can also be to become the helix angle gear; Said power input output can be opposite.
Beneficial effect of the present invention: because this wheel train structure adopts herringbone tooth to eliminate or reduces bearing axial force in the system, the bearing life height, and all carry by the radial floating of different gears and the axially adjustment/realization gear that floats simultaneously, design can make that system reliability is higher like this, and radial dimension is littler.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further:
Characteristic of the present invention will be become clearer by the detailed description of following three preferred embodiments, these preferred embodiments are just in order to illustrate the present invention, and it is a kind of application of the present invention, and can not think to limit the present invention.
Figure 1 shows that the basic layout schematic representation of using the present invention's one structure, power is by 3 inputs of a primary input axle, an input gear 1 and these axle 3 rigid joint, three output shafts 4 are arranged, all be connected with an output gear 2 on the every axle, this three output gears 2 identical and with input gear 1 simultaneously in engagement.Gear 1 and gear 2 are no groove herringbone tooth, and herringbone tooth both sides helix angle size is identical, and direction is opposite; Input gear 1 is an internal gear; Three output gears 2 can axially be adjusted the fixing or axial free floating in back, thereby make herringbone tooth two lateral tooth flanks all to carry, and the axial force that two lateral tooth flanks produce is cancelled out each other; But importing gear 1 radial floating simultaneously makes three output gears 2 all to carry; The geometrical axis fixed-site of three output shafts 4, power is by 4 outputs of three output shafts.
Arrow 5 expression radial direction, arrow 6 expression axial directions.
Structural representation for application another structure of the present invention shown in Figure 2, power is by 3 inputs of primary input axle, an input gear 1 and these axle 3 rigid joint, three output shafts 4 are arranged, all be connected with an output gear 2 on the every axle, this three output gears 2 identical and with 1 outer gearing simultaneously of input gear.Gear 1 and gear 2 have been the groove herringbone tooth, and the herringbone tooth both sides are the helicoid of symmetry; Input gear 1 is an external gear; Three output gears 2 connect with three output shafts 4 by spline 7 respectively, and axle 4 supports and fixes its axial location by bearing 8 respectively, and the other end of axle 4 also with three identical spur gear 9 rigid joint, these three spur gears 9 mesh simultaneously with spur gear 10, therefore transmission of power is to axle 4, be driven gear 9 rotations, thereby transmission of power to the main output shaft 11 of its connection exported by gear 10.In this device, spline 7 does not have axial constraint within the specific limits, so the axial free floating of gear 2, thereby makes herringbone tooth two lateral tooth flanks all to carry, and the axial force of two lateral tooth flanks generation is cancelled out each other; But gear 1 radial floating makes three gears 2 all to carry simultaneously, thereby makes three output shafts 4 all to carry.
Basic layout for another structure of application the present invention shown in Figure 3, power is imported from primary input axle 3A, an input gear 1A and this 3A rigid joint, respectively by three identical input gear 2A of spline 7A connection, gear 2A and input gear 1A mesh simultaneously on three output shafts 4; Other three identical output gear 2B also connect with output shaft 4 by spline 7B respectively, and the main output gear 1B outer gearing simultaneously on output gear 2B and the main output shaft 3B, and axle 4 supports and fix its geometrical axis position by bearing 8 respectively.Therefore power reaches main output gear 1B again after primary input gear 1A reaches axle 4, gear 1B and its 3B rigid joint, and power is by main output shaft 3B output.
Its middle gear 1A, gear 2A is no groove herringbone tooth, and both sides helix angle size equidirectional is opposite, spline 7A does not have axial constraint within the specific limits, make axially free floating of gear 2A, thereby make herringbone tooth two lateral tooth flanks all to carry, and the axial force that two lateral tooth flanks produce is cancelled out each other, but gear 1A radial floating makes three gear 2A all to carry simultaneously; Gear 1B and gear 2B are for there being the groove herringbone tooth, and helix angle size equidirectional is opposite, and assembling the time can adjust gear 2B axial position, confirming behind the even stand under load in herringbone tooth both sides it to be fixed, but gear 1B radial floating makes three gear 2B all to carry simultaneously, and does not have axial force.
