Two groups of angular contact ball bearings use back-to-back combination.
The support base connects transmission shaft root by deep groove ball bearing.
The first gear tail end is equipped with extension, and the extension passes through angular contact ball bearing connecting support seat.
The second gear is set to transmission shaft front end, and gland is installed in the second gear end.
Compared with prior art, the invention has the following advantages that
1, comprehensive off-load, run smoothly: the present invention will act on first by two groups of back-to-back combinations of angular contact ball bearing
Radial load and torque on gear, and off-load is to support base, the deep groove ball bearing between support base and transmission shaft balances
The radial load and torque of two gears guarantee stable drive；
2, compact-sized, stress is clear: first gear and transmission shaft are connected by flat key, to drive using first gear
Second gear, drive mechanism is compact,
3, rationally distributed, easily fabricated: whole device design is rationally, simple for structure, easily fabricated.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, all should belong to the scope of protection of the invention.
Embodiment
A kind of steering transmission support, the device include support base, transmission shaft, first gear and second gear, and first
By mutually connecting back to one group of angular contact ball bearing of setting between gear 5 and support base 1, first gear 5 also passes through flat key
2 13 connection transmission shafts 2, second gear 6 connect transmission shaft by flat key 1, and support base 1 is passed by the connection of deep groove ball bearing 17
Moving axis 2.
As shown in figures 1 and 3, first gear 5 and third gear 8 are spur gear, and third gear 8 drives first gear 5,
Second gear 6 and the 4th gear 9 are bevel gear, as shown in Fig. 2, on transmission shaft deep groove ball bearing and first gear 5 left end
Spacer ring 3 is provided between portion, support base right part is equipped with end cap 4 by soket head cap screw 3 14, and second gear right part passes through
Soket head cap screw 1 and soket head cap screw 2 11 are equipped with gland 7.
First gear 5 is supported in support base 1 with the first angular contact ball bearing 15 and the second angular contact ball bearing 16, and first jiao
Contact ball bearing 15 and the second angular contact ball bearing 16 are combined into back-to-back combination angular contact ball bearing (DB shape), such back-to-back
Combine angular contact ball bearing (DB shape) supporting role point between distance be it is widened, solve the support of first gear 5 first
Stability, balances radial load and torque when third gear 8 and first gear 5 are driven to first gear 5, and off-load is to propping up
Seat 1 is supportted, so as to steadily be driven.
In order to turn to transmission, first gear 5 cooperates flat key 2 13 and flat key 1 to impart power to the by transmission shaft 2
Two gears 6, then matched by the transmission of second gear 6 and the 4th gear 9 and, implement steering and be driven.
It is driven at this time in order to balance second gear 6 and the 4th gear 9 and increased combines angular contact ball bearing (DB to back-to-back
Shape) radial load and torque, 2 shaft end of transmission shaft increase deep groove ball bearing 17, balance increased radial load well
And torque, and off-load is to support base 1；The axial load of transmission shaft is also by back-to-back combination angular contact ball bearing (DB shape) simultaneously
Off-load is to support base 1.
When work, first gear 5 is rotated by external force, drives the transmission shaft 2 connecting with first gear 5 to rotate, 2 band of transmission shaft
Dynamic second gear 6 rotates, and being driven between first gear and second gear by flat key is also led between transmission shaft and second gear
Flat key rotation is crossed, the first angular contact ball bearing 15 and the second angular contact ball bearing 16 balance the torque of first gear and radial direction is born
It carries, deep groove ball bearing 17 balances the torque and radial load of second gear, first gear and the equal off-load of second gear to support
Seat keeps turning to transmission support even running.
