Abstract
The utility model discloses a kind of dedicated driving speed reducer take-off (propeller) shafts of high pedestal jib crane, including shaft assembly, gear and spacer sleeve；Shaft assembly includes being sequentially connected into a single integrated structure axis one, the shaft shoulder, axis two, keyway one is offered on axis one, is opened up on axis two there are two keyway two, two keyways two are symmetrical at 180 °, circlip groove is offered on axis two, two keyways two are between the shaft shoulder and circlip groove；Gear includes gear mass, and the center of gear mass offers dowel hole；Gear is sleeved on by key on axis two, and spacer sleeve is sleeved on the side on axis two and positioned at gear.Shaft assembly and gear are changed to separate structure by the utility model, and in disassembly process, active force acts on spacer sleeve, avoid housing failure, reduce repair risk and expense.
Description
Technical field
The utility model is related to speed reducer technical field more particularly to a kind of dedicated driving speed reducers of high pedestal jib crane
Take-off (propeller) shaft.
Background technology
The output shaft that KA97 and KA87 models speed reducer output hollow shaft matches at present is that gear is integrated knot with long axis
Structure, gear end diameter are bigger than the output hollow shaft diameter of gear-box, and in disassembly process, reducer shell needs stress, is dismounting
Cheng Zhonghui causes the phenomenon that shell is by pressure break, causes unnecessary damage, while influencing normal produce and use.Institute as shown in Figure 1, Figure 2
Show, to extract gear shaft out, the active force of a negative direction need to be applied on shell, shell has the risk of damage.
Utility model content
The utility model is to solve the problems, such as that existing reducer shell is flimsy, and it is dedicated to provide a kind of high pedestal jib crane
Driving speed reducer take-off (propeller) shaft.
In order to solve the above technical problems, the technical solution of the utility model is：The dedicated walking of high pedestal jib crane is slowed down
Machine take-off (propeller) shaft, including shaft assembly, gear and spacer sleeve；Shaft assembly include be sequentially connected into a single integrated structure axis one, the shaft shoulder,
Axis two offers keyway one on axis one, opens up that there are two keyways two on axis two, and two keyways two are symmetrical at 180 °, axis two
On offer circlip groove, two keyways two are between the shaft shoulder and circlip groove；Gear includes gear mass, and the center of gear mass opens up
There is dowel hole；Gear is sleeved on by key on axis two, and spacer sleeve is sleeved on the side on axis two and positioned at gear.
Further, the material of shaft assembly is 40Cr, quenched HB280-310.
Further, the material of gear is 40Cr, quenched HB280-310.
Further, the Z=16 of gear, M=9.
Shaft assembly and gear are changed to separate structure by the utility model, and in disassembly process, active force acts on spacer sleeve
On, housing failure is avoided, repair risk and expense are reduced.

Specific implementation mode
3-6 is described further specific embodiment of the present utility model below in conjunction with the accompanying drawings.
The dedicated driving speed reducer take-off (propeller) shaft of high pedestal jib crane, including shaft assembly, gear and spacer sleeve；Shaft assembly
Material be 40Cr, quenched HB280-310, shaft assembly includes being sequentially connected into a single integrated structure axis 1, the shaft shoulder 3, axis 28, axis
Keyway 1 is offered on one 1, is opened up on axis 28 there are two keyway 24, two 4 one-tenth 180 ° of keyways 2 are symmetrical, on axis 28
Circlip groove 5 is offered, two keyways 24 are between the shaft shoulder 3 and circlip groove 5；The material of gear is 40Cr, quenched HB280-
310, the Z=16 of gear, M=9, gear include gear mass 6, and the center of gear mass 6 offers dowel hole 7；Gear passes through key set
On axis 28, spacer sleeve is sleeved on the side on axis 28 and positioned at gear.
Power is obtained from speed reducer, is outputed power using gear, speed reducer power is passed into gear, separate form subtracts
The risk that shell damages in disassembly process is lacked.
More than, the only preferable specific implementation mode of the utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, according to the utility model
Technical solution and its utility model design be subject to equivalent substitution or change, should all cover the scope of protection of the utility model it
It is interior.
