Abstract
The utility model discloses an overload protector, which consists of a driving flange (4), a drive shaft (5) and an overload ring assembly which is damaged after bearing rating torque, wherein, the driving flange (4) consists of a circular tube body and an end flange body which is integrated into a whole with the circular tube body; the drive shaft (5) consists of a drive shaft body and an end drive shaft flange which is integrated into a whole with the drive shaft body; the circular tube body of the driving flange (4) is sleeved with the drive shaft body of the drive shaft (5); and the overload ring assembly is respectively movably connected with the circular tube body of the driving flange (4) and the drive shaft flange of the drive shaft (5). Due to adoption of the structure, when the input torque is oversized and exceeds the rating torque, the overload ring assembly is damaged; the torque input of a machine is cut off; and the machine is effectively protected and then the machine is prevented from being damaged, thereby the overload protector is simple in structure and convenient in assembly and is safe and reliable.
Description
Technical field
The utility model relates to the overload protective device that carries rated torque.
Background technique
Overload protective device commonly used will be imported transmission of power to transmission shaft by drive flange, drive housing by the frictional force between transmission shaft and the friction plate again, thus the drive machines motion.Complex structure not only; and the size of frictional force is the degree of tightness adjusting that tightens screw by end cap; and the pressure of change dish spring; thereby change the frictional force between transmission shaft and the friction plate; frictional force is too small can not transmit enough power; skidding easily burns out protector, excessively can't implement effective overload protection to complete machine.And the size of frictional force fully regulates relevantly with the degree of tightness that end cap tightens screw, and tightness is artificially regulated, and it is loaded down with trivial details that adjusting is installed.
The model utility content
Technical problem to be solved in the utility model is: a kind of overload protective device simple in structure, safe and reliable, easy for installation is provided.
Solve this technical problem; the technical solution of the utility model is: a kind of overload protective device; form by the overload circle assembly that destroys behind drive flange, transmission shaft and the carrying rated torque; drive flange is formed by the pipe body with its end flange body that forms one; transmission shaft is formed by the transmission shaft axis body with its transmission shaft flange that forms the end of one; the transmission shaft axis body socket of the pipe body of drive flange and transmission shaft, described overload circle assembly flexibly connect with the pipe body of described drive flange and the transmission shaft flange of transmission shaft respectively.
Described overload circle assembly is an elastic rubbery body, this elastic rubbery body in the form of a ring, forming one by the connecting ring between six uniform anchor plates and six anchor plates forms, all stud with the aluminium core that forms one in each anchor plate, wherein the axis of the aluminium core bolt hole of axis normal in other three anchor plates uniformly at intervals of the aluminium core bolt hole in three anchor plates uniformly at intervals with bolt hole.
The transmission shaft flange of described transmission shaft also flexibly connects with connection seat.
The utility model overload protective device adopts such structure, and during actual the use, overload protective device is imported power by drive flange, drives transmission shaft by overload circle assembly, is outputed power by transmission shaft again.Overload circle assembly can carry specified moment of torsion, and when input torque is excessive when surpassing its rated torque, overload is enclosed assembly destruction; thereby disconnect moment of torsion input to machine; machine is implemented effectively protection, avoid machine breakdown, such overload protective device is simple in structure, safe and reliable, easy for installation.

Embodiment
As shown in Figure 1 and Figure 2; a kind of overload protective device; form by drive flange 4, transmission shaft 5, overload circle assembly and coupling seat 1; drive flange 4 is formed by the pipe body with its flange body that forms the end of one; transmission shaft 5 is formed by the transmission shaft axis body with its transmission shaft flange that forms one; the transmission shaft axis body socket of the pipe body of drive flange 4 and transmission shaft 5, the transmission shaft flange and the connection seat 1 of transmission shaft 5 flexibly connect by bolt.Overload circle assembly is an elastic rubbery body 3, this elastic rubbery body 3 in the form of a ring, forming one by the connecting ring 7 between 8,9 and six anchor plates 8,9 of six uniform anchor plates forms, all has the aluminium core that the injection moulding all-in-one-piece has bolt hole in each anchor plate 8,9, wherein the axis of the aluminium core bolt hole of axis normal in other three anchor plates 9 uniformly at intervals of the aluminium core bolt hole in three anchor plates 8 uniformly at intervals.The anchor plate 8 interior aluminium core bolts hole that bolt 2 passes elastic rubbery body 3 are connected elastic rubbery body 3 with drive flange 4, the anchor plate 9 interior aluminium core bolts hole that bolt 6 passes elastic rubbery body 3 are connected elastic rubbery body 3 with transmission shaft 5.Connection seat 1 is connected with machine with drive flange 4 during practical set.
The utility model overload protective device, the coupling shaft bearing 1, only is made up of drive flange 4, transmission shaft 5 and overload circle assembly, and transmission shaft 5 directly is connected with machine with drive flange 4 during practical set.
Its working principle is as follows: overload protective device drives transmission shaft 5 by drive flange 4 input power by elastic rubbery body 3, thereby drives the machine rotation.Elastic rubbery body 3 can carry specified moment of torsion; when the moment of torsion of input is unstable; elastic rubbery body 3 plays buffer function; prevent that machine is subjected to the impact infringement; when input torque is excessive when surpassing its rated torque, elastic rubbery body 3 destroys, thereby disconnects the moment of torsion input to machine; machine is implemented effectively protection, avoid machine breakdown.
