Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provide it is a kind of avoid tooth shaft off-axis have overload protection
The gear-box of function.
In order to achieve the above object, the utility model adopts the following technical solutions: a kind of gear with overload protection function
Case, including cabinet, are arranged tooth shaft in cabinet, and the gear being meshed with tooth shaft is arranged on the outside of the middle part of tooth shaft, in tooth shaft head
End setting axle end baffle plate, is arranged with bearing in tooth shaft both ends periphery, it is fixed that first is arranged on the outside of the bearing for being located at tooth shaft head end
Be arranged the second distance collar away from ring, inside, be located at tooth shaft tail end bearing outside along far from tail end bearing direction successively
It is arranged with disc, third distance collar, nitridation set, is arranged oil baffle disc in disc periphery, oil seal cover is set in cabinet tail end,
Oil sealing is set between oil seal cover and nitridation set, is provided on the outside of oil seal cover for the butter to oil transportation between oil sealing and tooth shaft
Pipe, is arranged end cap in the outside of the first distance collar, and torsion identical with tooth shaft axis collinear and radial dimension is arranged in tooth shaft tail end
Square axis opens up groove in tooth shaft breech face, and torque axis head end radial dimension is less than torque axis axle body, the head end and tooth shaft of torque axis
It groove grafting and is connected by key, sets fluting in the axle body periphery of the torque axis adjacent with tooth shaft tail end.
Preferably: grooved section is triangle.
Preferably: the cabinet is made of the upper box and lower box parallel with tooth shaft axis, upper box and lower box
It is bolted.
The beneficial effects of the utility model are: the utility model under the structure situation for not changing original gear-box, designs
It is a kind of in overload or shock loading using a kind of structure type of the fluting of torque axis, in overload, torque axis is slotted
Place cut, to inside gear-box gear and axis play the role of protection, avoid the generation of gear-box tooth shaft off-axis phenomenon, protect
Effective production of production task is demonstrate,proved.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As depicted in figs. 1 and 2, the utility model includes cabinet 7, tooth shaft 1 is arranged in cabinet 7, outside the middle part of tooth shaft 1
The gear 8 being meshed with tooth shaft 1 is arranged in side, and axle end baffle plate 5 is arranged in 1 head end of tooth shaft, is arranged with bearing in 1 both ends periphery of tooth shaft
6, the outside for the bearing 6 for being located at 1 head end of tooth shaft is arranged the first distance collar 4, inside is arranged the second distance collar 15, positioned at tooth shaft
The outside of the bearing 6 of 1 tail end is successively arranged with disc 9, third distance collar 16, nitridation along the direction far from tail end bearing 6
Set 11, be arranged oil baffle disc 10 in 9 periphery of disc, 7 tail end of cabinet be arranged oil seal cover 13, oil seal cover 13 and nitridation set 11 it
Between be arranged oil sealing 12, be provided on the outside of oil seal cover 13 for the butter pipe 14 to oil transportation between oil sealing 12 and tooth shaft 1, first
End cap 3 is arranged in the outside of distance collar 4, and torque axis 2 identical with 1 axis collinear of tooth shaft and radial dimension is arranged in 1 tail end of tooth shaft,
Groove is opened up in 1 breech face of tooth shaft, 2 head end radial dimension of torque axis is less than 2 axle body of torque axis, the head end and tooth shaft 1 of torque axis 2
It groove grafting and is connected by key, sets fluting 17 in the axle body periphery of the torque axis 2 adjacent with 1 tail end of tooth shaft, 17 sections of slotting
