Specific embodiment
The utility model provide it is a kind of it is simple in structure, load overload when can cut off torsion transmission machine overload protection
Device, it is stuck so as to efficiently solve transmission, the problems such as the caused end rotating member damage of when motor rotation blockage and burn-down of electrical machinery.
Referring to Fig. 1, the mechanical overload protection device includes active gear shaft 10, overload protection part 20 and driven tooth shaft 30,
Wherein, for active gear shaft 10 for connecting input power with power source, power source herein is generally motor, active gear shaft 10 and electricity
The output terminal connection of machine, so as to which the power that motor provides is input to transmission system.Driven gear ring 30 is used to connect with external load
It connects, so as to export power outward, driven gear ring 30 is set in outside active gear shaft 10.
In the prior art, driven gear ring 30 is directly set on active gear shaft 10, and this rigid connection causes occurring
Carry it is stuck, when driven gear ring 30 can not rotate, often because torsion is excessive so that final drive damage and burn-down of electrical machinery.
The mechanical overload protection device of the utility model is arranged between active gear shaft 10 and driven gear ring 30 with bullet
The overload protection part 20 of property, the overload protection part 20 of the elasticity can generate deformation beyond normal torque, so as to make
It obtains and generates relative displacement between active gear shaft 10 and driven gear ring 30, realize the cut-out of torsion transmission, both protect power source
The motion after the device is also protected such as motor, and itself will not be damaged.
With continued reference to Fig. 1, the active gear shaft 10 of the utility model is equipped with along its first circumferentially distributed driving cog 101,
The first arc groove 102 is formed between adjacent first driving cog 101, and the circular arc of adjacent first arc groove 102 is tangent, institute
It states overload protection part 20 to be set on the active gear shaft 10, and fits with the active gear shaft 10.
The overload protection part 20 is arranged in order to form one by including multiple elastic cylinders 21, each elastic cylinder 21
A cylindrical sleeve being set in outside active gear shaft 10.The elastic cylinder 21 can be that solid cylinder may be hollow cylinder
Body, it is contemplated that the complexity of processing and manufacturing, the present embodiment preferably the elastic cylinder 21 be solid cylinder, the filled circles
Cylinder is made of elastic material, such as can be polyurethane rubber, PU.
The driven gear ring 30 is set on the overload protection part 20, and the driven gear ring 30 is close to the overload protection
The inner wall of part 20 is equipped with along the second circumferentially distributed driving cog 301 of the driven gear ring 30, adjacent second driving cog 301
Between form the second arc groove 302, the circular arc of adjacent second arc groove 302 is tangent.
The elastic cylinder 21 is placed between 102 and second arc groove 302 of the first arc groove, and the elasticity
The central axis of the central shaft of cylinder 21 and 102 and second arc groove 302 of the first arc groove.Due to adjacent
The circular arc of one arc groove 102 is tangent, and the circular arc of adjacent second arc groove 302 is tangent, when each elastic cylinder 21 is placed in
When between the first arc groove 102 and the second arc groove 302 so that adjacent spring cylinder 21 is in tangent state.
The operation principle of the mechanical overload protection device is as follows：When power source drives 10 rotary input power of active gear shaft
When, due to the central shaft of the first arc groove 102 on active gear shaft 10 and the central shaft of elastic cylinder 21 and driven gear ring
The central axis of the second arc groove 302 on 30, therefore, in the case where elastic cylinder 21 is not deformed, actively
Tooth shaft 10 will not generate displacement, the two meeting synchronous rotary, so as to achieve the purpose that normally to be driven with driven gear ring 30.
When the load being connected on driven gear ring 30 transfinite i.e. overload lead to occur stuck stall when, driven gear ring 30 can not
Rotation, but power source still conveys power to active gear shaft 10 at this time, due to elastic cylinder 21 be placed in the first arc groove 102 with
Between second arc groove 302, which can be in the first driving cog 101 with being generated under the extruding of the second driving cog 301
Deformation, outside wall surface can be flattened by moment, and be pushed on driven gear ring 30 by the first driving cog 101 on active gear shaft 10 simultaneously
The second adjacent arc groove 302, form all elastic cylinder of overload protection part 20 since the above process is happened at simultaneously
On body 21, i.e., all elastic cylinder 21 constantly repeats：The process of deformation → movement → deformation → movement ..., it is achieved thereby that
The cut-out that torsion transmits so that power source such as motor is unlikely to burn, be also unlikely to power continue to be transmitted to trouble location make therefore
Barrier upgrading.
In one preferred embodiment, the active gear shaft 10 includes driving shaft 11 and is set in the driving shaft 11
On the first cylinder 12, first driving cog 101 is uniformly distributed on its outer surface along the circumferential direction of first cylinder 12, institute
The first driving cog 101 is stated as strip, and along the axially extending of first cylinder 12, is formed in adjacent first driving cog 101
Between the first arc groove 102 therefore also along the axially extending of the first main body 12.
The driven gear ring 30 includes the second cylinder 31 and the outer ring 32 being set on second cylinder 31, the outer ring
32 are used to connect with external load.The outer ring 3 can be gear, sprocket wheel, belt pulley or shaft coupling, it is, of course, also possible to be it
His form, spreads out of power as long as can realize, the utility model is not restricted this.
Second cylinder 31 is set on the overload protection part 20, and second driving cog 301 is along second column
The circumferential direction of body 31 is evenly distributed on its inner wall.Second driving cog 301 is strip, and along the axis of second cylinder 31
To extension, therefore the second arc groove 302 being formed between adjacent second driving cog 301 prolongs also along the axial direction of the second main body 31
It stretches.
The size of torsion of the tooth height of first driving cog 101 and the second driving cog 301 with generating is related, and general torsion is got over
Greatly, tooth Gao Yuegao.In addition, the tooth height of driving cog is also related with the material of elastic cylinder 21, its bullet for having of different materials
Property it is different, therefore, the deformation degree of elastic cylinder 21 made of different materials is also different, it is preferred that the first driving cog 101
High size that is determining while considering born torsion and the material of elastic cylinder with the tooth of the second driving cog 301.
In one preferred embodiment, the tooth of the tooth height of first driving cog 101 and second driving cog 301
It is high identical, manufacture difficulty can be both reduced in this way, can also achieve the effect that preferably to cut off torsion transmission.Certainly, it needs
Bright, the tooth height of the first driving cog 101 and the second driving cog 301 can also be different, and the tooth height of such as the first driving cog 101 is less than
The tooth of second driving cog 301 is high.
Since elastic cylinder 21 can be due to generating during deformation, movement with driven gear ring 30 and active gear shaft 10
It rubs and heat, elastic cylinder 21 is burnt out due to no heating of oil in order to prevent, in one embodiment, in overload protection part 20
Installation site filling lubricating substance, the non-corrosive lubricating grease such as vaseline or to rubber, it is ensured that cut in torsion transmission
Deformation during disconnected was not only smooth, but also can protect overload protection part 20, so as to extend the service life of the device.
