A flange and an outer ring are connected with a spline housing, a steel tube and a shaft sleeve into a whole through a steel ball and a spline shaft head; a spring is sleeved between spring seats; a roller needle bearing is installed between a shaft sleeve of an overloading protection device and a shaft head; the safety pin passes through a hole vertical to the shaft sleeve and the shaft head; a pressing plate is installed on the end part of the shaft head; straight grooves which are internally provided with shaft retainer rings are formed on the two end surfaces of the safety pin; and in overloading, the safety pin is cut off, the shaft head and the shaft sleeve are separated, motive power transmission is stopped through the relative rotation of the bearing installed between the shaft head and the shaft sleeve, the coupling and other externally linked devices are maximally protected, the device damage caused by overloading is avoided, and the economic loss caused by invalid electric appliance protection is reduced. The self-homing-type Rzeppa synchronous universal coupling with the safety pin provided by the utility model is high in safety coefficient and reliability, is important supplement of the overloading protection of electrical appliances, the influence of over great impact on the service life of the coupling is solved effectively, the safety hazard can be eliminated maximally, the maintenance is convenient and rapid, and the cost is low.
Description
Technical field
The utility model relates to the coupling of mechanical coupling, is the self-homing type ball cage synchronous universal coupling that is used for the band safety pin of occasions uses such as impact force is big, overload is not too frequent, the non-ferrous metal of continuous operation, petroleum industry specifically.
Background technique
Disclosing a kind of denomination of invention in the existing technology is the utility model patent of " ZL02265760.6 " for " self-homing type ball cage synchronous universal coupling ", the patent No., and compact structure is reliable, installs, changes easy to maintenance, locking and obvious from the effect that playbacks.But when the equipment of outreaching such as motor, speed reducer or machine work do-part impact when excessive, the coupling of this structure can not stop transmission automatically, can't protect the equipment that links with coupling, has a strong impact on the working life of coupling operational reliability and associated equipment.
Summary of the invention
For overcoming the deficiency of existing technology; The goal of the invention of the utility model is to provide a kind of self-homing type ball cage synchronous universal coupling with safety pin; The overload protection arrangement that has safety pin through installing between axle sleeve and spindle nose; To improve the working life of coupling, protect coupling and miscellaneous equipment to greatest extent.
For realizing above-mentioned purpose; In the endoporus of the outer ring of the utility model baffle plate is housed, outer ring and flange are welded as a whole, and many straight flute roads that equidistantly distribute along circumference are arranged on outer ring and the spline axle head; Between steel ball is housed; Steel ball is installed in the window of retainer, is contained in the groove of outer ring with the back-up ring that limits the retainer displacement, and sealing system is equipped with in the end of outer ring; Spline housing is connected through spline with spline axle head; Spline housing, axle sleeve and steel pipe are welded as a whole, and spring seat one is connected on the spline axle head, and spring seat two is fixed in the steel pipe; Spring housing is connected between spring seat one and the spring seat two, it is characterized in that: between axle sleeve and spindle nose overload protection arrangement is housed.
Between the axle sleeve of said overload protection arrangement and spindle nose needle bearing is housed; Safety pin passes and axle sleeve, the perpendicular hole of spindle nose; The pressing plate that is used for the axially locating needle bearing is equipped with in the end of spindle nose, and the both ends of the surface of safety pin have straight trough, in two straight troughs, shaft retaining ring is housed.
During overload, safety pin is cut off, and makes between spindle nose and the axle sleeve and throws off; In disconnecting process, spindle nose and axle sleeve relatively rotate through the bearing of installing therebetween, stop power transmission; Protect coupling itself and other to outreach equipment to greatest extent; Like motor, speed reducer and machine work do-part, avoided the device damage that causes because of overload, reduced the economic loss that electric prospection lost efficacy and causes.
The utility model is compared with existing patented technology, has the following advantages:
1, the occasion of, continuous operation big in impact force; Can cut off power source automatically through the safety pin overload protection arrangement, safety coefficient and reliability are high, are the important supplement to equipment electrical equipment overload protection; Efficiently solve ball cage coupling because of impacting excessive influence, reduce user cost its life-span;
When 2, transshipping, safety pin is cut off, and makes between spindle nose and the axle sleeve to throw off; In disconnecting process, spindle nose and axle sleeve relatively rotate through the bearing of installing therebetween, steadily idle running; Can not throw off to throw away and injure peripheral personnel and equipment by a crashing object, the safety pin of fracture is pressed in the pin-and-hole by axle bumper, can not throw away along with the rotation of right axle shaft; Be convenient to cleaning, eliminated potential safety hazard to greatest extent;
3, the safety pin because of fracture can take out in pin-and-hole very soon, makes the replacing of safety pin more convenient, has shortened fault power time.
4, the manufacturing maintenance cost is low, is convenient to promote.
