Abstract
With a Self-homing type Rzeppa synchronoccs universal coupling for safety pin, for the industry such as non-ferrous metal, oil.Flange, outer ring are connected as a single entity through spline axle head and spline housing, steel pipe, axle sleeve by steel ball; spring housing is connected between spring seat; between the axle sleeve of overload protection arrangement and spindle nose, needle bearing is housed; safety pin is through the hole perpendicular with axle sleeve, spindle nose; pressing plate is equipped with in spindle nose end, and safety pin both ends of the surface have the straight trough built with shaft retaining ring.During overload, safety pin is cut off, and spindle nose and axle sleeve are thrown off; bearing by installing therebetween relatively rotates, and stops power transmission, protects coupling itself and other peripheral equipment to greatest extent; avoid causing device damage because of overload, reduce electric prospection inefficacy and cause economic loss.Safety coefficient of the present invention and reliability high, be the important supplement to equipment electrical equipment overload protection, efficiently solve coupling excessive to its aging effects because impacting, can eliminate safe hidden trouble to greatest extent, fast easy to maintenance, cost is low.
Description
Technical field
The present invention relates to the coupling of mechanical coupling, is the Self-homing type Rzeppa synchronoccs universal coupling of large for impact force, that overload is not too frequent, the occasion such as non-ferrous metal, petroleum industry that is continuous operation uses band safety pin specifically.
Background technique
Disclose the patent of invention that a kind of denomination of invention is " Self-homing type Rzeppa synchronoccs universal coupling ", the patent No. is " ZL02265760.6 " in prior art, compact structure is reliable, install, change easy to maintenance, the locking and successful that certainly playbacks.But when motor, speed reducer or machine work enforcement division grade peripheral equipment impact excessive time, the coupling of this structure can not stop transmission automatically, cannot protect the equipment be connected with coupling, has a strong impact on the working life of coupling operational reliability and associated equipment.
Summary of the invention
For overcoming the deficiencies in the prior art; goal of the invention of the present invention is to provide a kind of Self-homing type Rzeppa synchronoccs universal coupling with safety pin; by installing the overload protection arrangement with safety pin between axle sleeve and spindle nose; to improve the working life of coupling, protect coupling and miscellaneous equipment to greatest extent.
For achieving the above object, in the endoporus of outer ring of the present invention, baffle plate is housed, outer ring and flange welding are integrated, the straight flute road that outer ring and spline axle head have many circumferentially to equidistantly distribute, between steel ball is housed, steel ball is arranged in the window of retainer, is contained in the groove of outer ring with the back-up ring limiting retainer displacement, and sealing system is equipped with in the end of outer ring; Spline housing and spline axle head pass through spline joint; spline housing, axle sleeve and steel-pipe welding are integrated, and spring seat one is connected on spline axle head, and spring seat two is fixed in steel pipe; spring housing is connected between spring seat one and spring seat two, it is characterized in that: between axle sleeve and spindle nose, overload protection arrangement is housed.
Between the axle sleeve of described overload protection arrangement and spindle nose, needle bearing is housed; safety pin is through the hole perpendicular with axle sleeve, spindle nose; the pressing plate for 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, at two straight troughs built with shaft retaining ring.
During overload; safety pin is cut off; make to throw off between spindle nose and axle sleeve; in disconnecting process, spindle nose and axle sleeve are relatively rotated by the bearing installed therebetween, stop power transmission; protect coupling itself and other peripheral equipment to greatest extent; as motor, speed reducer and machine work do-part, avoid the device damage caused because of overload, decrease electric prospection and to lose efficacy the economic loss caused.
The present invention, compared with existing patented technology, has the following advantages:
1, the occasion of, continuous operation large in impact force, automatically cut off power source by safety pin overload protection device, safety coefficient and reliability high, be the important supplement to equipment electrical equipment overload protection, efficiently solving ball cage coupling because impacting the excessive impact on its life-span, reducing user cost;
2, during overload, safety pin is cut off, make to throw off between spindle nose and axle sleeve, in disconnecting process, spindle nose and axle sleeve are relatively rotated by the bearing installed therebetween, steady idle running, can not throw off to throw away and injure periphery personnel and equipment by a crashing object, the safety pin of fracture is pressed in pin-and-hole by axle bumper, can not throw away along with the rotation of right axle shaft, be convenient to cleaning, eliminate potential safety hazard to greatest extent;
3, because the safety pin of fracture can take out very soon in pin-and-hole, make the replacing of safety pin more convenient, shorten fault power time.
4, manufacture maintenance cost low, be convenient to promote.
Accompanying drawing explanation
Accompanying drawing 1 is structure diagram of the present invention.
Embodiment
As shown in Figure 1, baffle plate 2 is housed in the endoporus of outer ring 5, overcoat 5 and flange 1 are welded as a whole, and compact structure is reliable, the straight flute road that outer ring 5 and spline axle head 9 have many circumferentially to equidistantly distribute, between steel ball 4 is housed, steel ball 4 is arranged in the window of retainer 3, and back-up ring 6 is contained in the groove of outer ring 5, to limit the displacement of retainer 3, sealing system is equipped with in the end of outer ring 5, and sealing system comprises seal closure 7 and clip 8, spline housing 10 and spline axle head 9 pass through spline joint, spline housing 10, axle sleeve 18 and steel pipe 15 are welded as a whole, spring seat 1 screw 12 is connected on spline axle head 9 through packing ring 11, spring seat 2 16 rivet 17 is fixed in steel pipe 15, spring 14 is socketed between spring seat 1 and spring seat 2 16, between the axle sleeve 18 of overload protection arrangement and spindle nose 21, needle bearing 22 is housed, safety pin 20 passes and axle sleeve 18, the hole that spindle nose 21 is perpendicular, the end screw 24 of spindle nose 21 is equipped with the pressing plate 23 for axially locating needle bearing 22, the both ends of the surface of safety pin 20 have straight trough, at two straight troughs built with shaft retaining ring 19, in case after safety pin cut off, throw away and injure periphery personnel and equipment by a crashing object, the safety pin of fracture is pressed in pin-and-hole by shaft retaining ring 19, can not throw away along with the rotation of right axle shaft, be convenient to cleaning, eliminate potential safety hazard to greatest extent.The structure such as flange, outer ring of right-hand member is the same with left end.
