Abstract
A kind of shaft coupling with function of safety protection, including the first half a coupler and the second half a coupler, second half a coupler are inlaid into the first half a coupler, pass through safety pin axis connection between first half a coupler and the second half a coupler.When driven member is stuck, the torque of the transmission between the first half a coupler and the second half a coupler is caused to increase sharply, when torque value increases to certain value, safe axis pin is cut, and the connection between the first half a coupler and the second half a coupler disconnects, to play the function of security protection.
Description
Technical field
The present invention relates to a kind of shaft coupling for transmitting torque, more particularly to a kind of shaft couplings with function of safety protection
Device.
Background technology
Shaft coupling is common component in machine driving, is mainly used to coupling spindle and axis or coupling spindle and other pivoting parts
Intermediate transmission mechanism, with transmit movement and torque.In the transmission system of current most of equipment, driving link and driven member are all
It is directly connected to by gear, spline engagement or other modes.In transmission system use the above connection type, when from
When moving part is stuck because of failure, since driven member and driving link can not be disconnected, and causes driving link and driven member while being damaged.
In the equipment to run at high speed, it is badly damaged or even scrap that such failure may result in equipment.
Invention content
Goal of the invention：In order to solve the above technical problem, the present invention provides one kind when driven member is stuck driving link with from
The shaft coupling with function of safety protection that moving part can be detached from.
Technical solution：A kind of shaft coupling with function of safety protection, including the first half a coupler and the second half a coupler, institute
It states the second half a coupler to be inlaid into the first half a coupler, passes through safety between first half a coupler and the second half a coupler
Axis pin connects.When driven member is stuck, the torque of the transmission between the first half a coupler and the second half a coupler is caused to increase rapidly
Add, when torque value increases to certain value, safe axis pin is cut, the connection between the first half a coupler and the second half a coupler
It disconnects, to play the function of security protection.
Preference, first half a coupler one end are equipped with first flange side, and second half a coupler is equipped with the second method
Lan Bian, the first flange are mutually adjacent to while with second flange, and circumferencial direction is equipped at least three groups and runs through the first method
It is blue while and the through-hole for installing safe axis pin when second flange.
Preference, the second half a coupler are embedded in completely in the first half a coupler, and first half a coupler one end is equipped with
Be respectively equipped in sleeve for accommodating the second half a coupler, the sleeve and the second half a coupler circumferential wall quantity, position and
The first bearing pin mounting hole and the second bearing pin mounting hole for installing safe axis pin of size all same.
Advantageous effect：The present invention can be cut by safe axis pin, entire shaft coupling when to realize driven member failure
Device disconnects, to play the function of protection driving link.
Description of the drawings
Fig. 1 is the structural schematic diagram of first embodiment of the invention.
Fig. 2 is the structural schematic diagram of second embodiment of the invention.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples.

Safe axis pin 3 connects.Described first half a coupler, 1 one end is equipped with first flange side 11, and second half a coupler 2 is equipped with second
Flange 21, the first flange while 11 with second flange while 21 be mutually adjacent to, and circumferencial direction is passed through equipped at least three groups
Wear first flange at 11 and second flange 21 for installing the through-hole of safe axis pin 3.
Embodiment two
As shown in Fig. 2, a kind of shaft coupling with function of safety protection, including the first half a coupler 1 and the second half a coupler 2, institute
It states the second half a coupler 2 to be inlaid into the first half a coupler 1, pass through between first half a coupler, 1 and second half a coupler 2
Safe axis pin 3 connects.Second half a coupler 2 is embedded in completely in the first half a coupler 1, and described first half a coupler, 1 one end is set
It is useful for accommodating the sleeve 12 of the second half a coupler 2, number is respectively equipped in 2 circumferential wall of the sleeve 12 and the second half a coupler
Amount, the first bearing pin mounting hole 13 and the second bearing pin mounting hole 22 for installing safe axis pin 3 of position and size all same.
