Abstract
The utility model discloses a kind of pin type safety coupling.It include No.1 connecting bushing, No. two connecting bushings and and the connecting tube between No.1 connecting bushing and No. two connecting bushings, there is the installation end for extending into connecting tube on No.1 connecting bushing, bearing is installed between the installation end of No.1 connecting bushing and the endoporus of connecting tube, it is provided between connecting tube and No.1 connecting bushing and No.1 bolt is installed, the groove being provided with No.1 bolt at No.1 connecting bushing and connecting tube contact surface, is provided with No. two bolts between connecting tube and No. two connecting bushings.It the advantage is that：Work as torque overload when running at high speed, No.1 bolt is broken at groove surface, and bearings connecting tube, prevents connecting tube from throwing away; play the role of safeguard protection, such as overload, also function to protection equipment effect; No.1 bolt is only needed to change during shutdown, improves security reliability, reduces replacement cost.
Description
Technical field
It the utility model is related to a kind of shaft coupling for transmitting moment of torsion, more particularly to a kind of pin type safety coupling.
Background technology
Existing shaft coupling, generally comprises left connecting bushing, right connecting bushing and and is connected to left connecting bushing and the right side
Connecting tube between connecting bushing, direct bolt between connecting tube and left connecting bushing and between connecting tube and right connecting bushing
Directly tighten fixation, bolt shearing force and frictional force leaned on for transmitting moment of torsion, use existing this shaft coupling usually exist with
Lower problem, on the one hand, shaft coupling is two shaft parts of connection, and moment of torsion is transmitted in one end by gear reducer, in the case that rotating speed is fast, if one
Denier is broken, and connecting bushing deceleration pusher side and connecting tube will separate, it will hidden danger be brought to periphery personnel safety, to enterprise and employee
Massive losses are produced, still further aspect, once the bolt aging on shaft coupling, when usage time is long, bolt strength weakens, and also can
Bring hidden danger to production safety, another further aspect, the good and bad jumbled together causes shear strength to differ for the bolt of in the market, also brings safety
Hidden danger.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of simple in structure, design is reasonable, safe and reliable and safeguard
The low pin type safety coupling of cost.
In order to solve the above-mentioned technical problem, the pin type safety coupling of the utility model, including No.1 connecting bushing, two
Number connecting bushing and and the connecting tube between No.1 connecting bushing and No. two connecting bushings, have on No.1 connecting bushing
The installation end of connecting tube is extend into, bearing, connecting tube are installed between the installation end of No.1 connecting bushing and the endoporus of connecting tube
It is provided between No.1 connecting bushing and No.1 bolt is installed, is provided with No.1 bolt positioned at No.1 connecting bushing and connection
Groove at pipe contact surface, is provided with No. two bolts between connecting tube and No. two connecting bushings.
The one end coordinated in the connecting tube with installation end is provided with annular convex platform, and the medial extremity of the installation end is provided with
Outer bearing is simultaneously spacing by the outboard end of annular convex platform, and the outboard end installation of the installation end has from connecting tube away from installation
The inner bearing of side placement is held, the inner bearing is spacing by the medial extremity of annular convex platform.
The left and right ends of the connecting tube are both provided with connecting flange, on the No.1 connecting bushing and No. two connecting bushings
It is provided with mounting flange corresponding with the connecting flange of the left and right sides respectively.
The utility model has the advantage of：Due to the No.1 connecting bushing with installation end of setting, No.1 connecting bushing
Installation end and connecting tube endoporus between the bearing installed and with No.1 connecting bushing and connecting tube contact surface
Groove No.1 bolt, torque overload is worked as when running at high speed, No.1 bolt is broken at groove surface, bearings connection
Pipe, prevents connecting tube from throwing away, plays the role of safeguard protection, such as overloads, and also functions to protection equipment and acts on, when shutdown only needs to change
No.1 bolt, improves security reliability, reduces replacement cost.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model pin type safety coupling.
