Utility model content
To solve the above-mentioned problems, a kind of protector for avoiding motor overload is provided, the utility model devises a kind of light
Type transmission shaft protector.
The utility model the specific technical proposal is: a kind of light-duty transmission shaft protector, including it is driving shaft, driven shaft, outer
Shell and chain wheel, driven shaft upper end are equipped with flange, and the flange upper surface is installed with the first chain wheel, is engaged above the first chain wheel
There is the second chain wheel, the flange upper end is equipped with shell by dismountable mode, and the shell is the first chain wheel of buckle closure and the
The lid-like of two chain wheels, end are equipped with the perforation of corresponding driving shaft；Driving shaft protrudes into the perforated inner point end equipped with non-
Round tenon head, the second chain wheel end are equipped with the mounting groove of the corresponding non-circular tenon；The driving shaft outer wall is socketed with corresponding second
Between chain wheel and shell.
Preferably, flange is connected in outer casing end by the first bolt.Bolster is spring or rubber pad.
Preferably, the blind hole of corresponding non-circular tenon outer diameter is equipped in the middle part of the first chain wheel.Oiling is equipped in the middle part of driving shaft
Hole, the oil filler point extend downward into non-circular tenon end；No less than one, which is extended with, to two sides in the middle part of oil filler point extends to the
The branch hole of one chain wheel.
Oil filler point upper end is equipped with the oil inlet for extending to driving shaft outer wall, and the oil inlet is equipped with silk plug.
Preferably, outer casing end is equipped with about the equally distributed wire hole in its axle center, and the wire hole screw-internal thread fit has
Second bolt of lower end conflict bolster.The non-circular tenon is milling square structure.
Advantageous effects: the first chain wheel or the second chain wheel are in meshing state under conventional sense, and driven shaft is driven to execute
Normal kinetic energy transmitting；When load excessive or abnormal conditions occurs in load end driven shaft, the second chain wheel is moved up and is squeezed
Rubber pad, the first chain wheel and the second chain wheel component disengage at this time, to realize the purpose of protection driving motor and transmission shaft.
Detailed description of the invention
Fig. 1 is the utility model structure chart；
Fig. 2 is 1 driven shaft in the utility model section figure figure, 2 driving shafts, 3 shells, 4 second chain wheels, 5 rubber pads, 6 the
One bolt, 7 first chain wheels, 8 oil filler points, 9 second bolts.
Specific embodiment
A kind of light-duty transmission shaft protector, referring to Fig. 1-2: including driving shaft 2, driven shaft 1, shell 3 and chain wheel, driven shaft
1 upper end is equipped with flange, and the flange upper surface is installed with the first chain wheel 7, the second chain wheel 4 has been engaged above the first chain wheel 7,
The flange upper end is equipped with shell 3 by dismountable mode, and the shell 3 is buckle closure the first chain wheel 7 and the second chain wheel 4
Lid-like, end are equipped with the perforation of corresponding driving shaft 2；Driving shaft 2 protrudes into the perforated inner point end and is equipped with non-circular tenon,
Second chain wheel, 4 end is equipped with the mounting groove of the corresponding non-circular tenon；2 outer wall of driving shaft is socketed with corresponding second chain wheel 4
Between shell 3.
Flange is connected in 3 end of shell by the first bolt 6.Bolster is spring or rubber pad 5.
The blind hole of corresponding non-circular tenon outer diameter is equipped in the middle part of first chain wheel 7.Oil filler point 8, the note are equipped in the middle part of driving shaft 2
Oilhole 8 extends downward into non-circular tenon end；8 middle part of oil filler point is extended with no less than one to two sides and extends to the first chain wheel 7
Branch hole.
8 upper end of oil filler point is equipped with the oil inlet for extending to 2 outer wall of driving shaft, and the oil inlet is equipped with silk plug.
3 end of shell is equipped with about the equally distributed wire hole in its axle center, and it is slow that the wire hole screw-internal thread fit has lower end to contradict
Second bolt 9 of stamping.The non-circular tenon is milling square structure.
The first chain wheel 7 or the second chain wheel 4 are in meshing state under conventional sense, and driven shaft 1 is driven to execute normal kinetic energy
Transmitting；When load excessive or abnormal conditions occurs in load end driven shaft 1, the second chain wheel 4 moves up and squeezes rubber pad 5,
The first chain wheel 7 and 4 component of the second chain wheel disengage at this time, to realize the purpose of protection driving motor and transmission shaft.
Oil filler point 8 is set, oil injecting lubricating is carried out to two chain wheels by oil filler point 8, guarantees that the two does the lubrication relatively rotated,
The overload situations of the excessive formation of torsion needed for avoiding the two frictional force is excessive the second chain wheel 4 is caused to turn one's head；Colleague's setting branch hole, energy
Enough lubrications to the second chain wheel 4 and tenon avoid the two frictional force is excessive from causing the later excessive formation of required torsion of the second chain wheel 4
Overload situations.
Second bolt 9 is set, by the second bolt 9 squeeze rubber pad 5, can as needed turn the second bolt 9 to rubber
Rubber mat 5 is squeezed, to realize the adjustment to overload pressure size.
