Abstract
The utility model discloses universal coupling for straightener relates to the universal coupling field that is used for sheet material straightener. The novel steel ball connecting device is composed of a fixed shaft head (1), steel balls (2), keys (3), a movable shaft head (4), a connecting shaft (5), a retainer ring (6), a movable shaft head (7) and a set screw (8). The fixed shaft heads (1) at the two ends are respectively connected and positioned with the movable shaft heads (4) and the movable shaft heads (7) at the two sides of the middle part through steel balls (2), and the movable shaft heads (4) and the movable shaft heads (7) are respectively connected and positioned with the connecting shafts (5) between the movable shaft heads and the movable shaft heads through keys (3) and set screws (8); the retainer ring (6) is positioned at the left end of the movable shaft head (7) to axially position the connecting shaft (5), and the steel balls (2) are arranged in grooves at the end parts of the fixed shaft heads (1) and can freely rotate. The universal coupling for the straightener has the advantages of small volume, good rigidity, large transmission torque, reliable operation and convenient assembly and disassembly.
Description
Technical field:
The utility model relates to straightener and uses the universal coupling field.
Background technology:
Continuous development along with society, in departments such as automobile making, household electric appliances, flatness for plate surface requires more and more higher, this straightener that just needs to produce pony roll footpath multiple roll number satisfies the customer requirements and the market demand, owing to require the smoothing roll number of straightener many, therefore under the multiple roll number, the roller footpath of smoothing roll will be little, so just require the volume of its universal coupling little, and require the torque of carrying big, the universal coupling of being produced on the market can not satisfy this requirement, therefore, just needs the novel straightener universal coupling of design.
Summary of the invention:
The purpose of this utility model provides a kind of straightener universal coupling, between fixing spindle nose and movable spindle nose, adopt steel ball to be connected the location, thereby make universal coupling that certain axial knuckle be arranged, and, between movable spindle nose and connecting axle, transmit moment of torsion with key, make movable spindle nose certain stroke axially arranged along the direction of key, this has just satisfied the transmission device requirement of straightener.
A kind of straightener universal coupling, it is characterized in that two fixedly spindle nose (1) respectively each with movable spindle nose (4) and movable spindle nose (7) between be connected and be positioned with steel ball (2); Movable spindle nose (4), movable spindle nose (7) respectively with they between connecting axle (5) between each adopts and has key (3) to be connected the location with holding screw (8); Back-up ring (6) axial location is in connecting axle (5).
This straightener has fixedly spindle nose with universal coupling at its two ends, the fixedly spindle nose at these two ends all adopts steel ball to be connected the location respectively with between the movable spindle nose on both sides, middle part, therefore, can make universal coupling have certain axial knuckle, adopt key to be connected the location respectively between two movable spindle noses of this of mid portion both sides and the connecting axle with holding screw, transmit torque, so just can make these two movable spindle noses on mid portion both sides respectively certain elongation, shortening amount can be arranged along the direction of its key; In addition, adopt a back-up ring that connecting axle is located at axial direction, like this, when universal coupling need be dismantled, as long as unload back-up ring, operation was not only convenient but also reliable.
This universal coupling has the following advantages:
1, volume is little, and rigidity is good, and the moment of torsion of transmission is big.
2, stable drive is reliable, and is easy to loading and unloading, long service life.
Description of drawings:
Fig. 1: straightener universal coupling sectional structure chart.
Fig. 2: fixing spindle nose (1) end face front view.
Fig. 3: fixing spindle nose (1) vertical view cutaway drawing.
The specific embodiment:
Referring to Fig. 1: this straightener with universal coupling by fixedly spindle nose (1), steel ball (2), key (3), movable spindle nose (4), connecting axle (5), back-up ring (6), movable spindle nose (7), holding screw (8) are formed.
With the universal coupling two ends a fixedly spindle nose (1) is arranged respectively at this straightener, the fixedly spindle nose (1) at two ends respectively is connected the location by steel ball (2) respectively with between the movable spindle nose (4) on both sides, middle part and the movable spindle nose (7), and movable spindle nose (4) and movable spindle nose (7) adopt key (3) to be connected the location with holding screw (8) respectively with connecting axle (5) between them; Other has a back-up ring (6) to be positioned at movable spindle nose (7) left end, makes connecting axle (5) make axial location.Above-mentioned mounting structure makes movable spindle nose (4) and movable spindle nose (7) certain stroke to be arranged along connecting axle (5) axial direction, and just movable spindle nose (4) and movable spindle nose (7) can be done left and right sliding on key (3).
The incision end face all spherical in shape of movable spindle nose (4) and movable spindle nose (7) is so that make these two movable spindle noses make axial rotation with intermediate connecting shaft (5).
Fixedly respectively interlaced by 1/4th quadrants between the end face of spindle nose (1) and movable spindle nose (4) and movable spindle nose (7), wherein 1/4th end faces at two diagonal angles protrude outside, in the end face at all the other two diagonal angles is then recessed down.And steel ball (2) just is installed in the end recesses of fixing spindle nose (1), and steel ball (2) can freely rotate in this end recesses, between steel ball (2) and groove between otch two circular arcs the gap be 0.03～0.05 millimeter, steel ball (2) diameter is 24 millimeters of .Must be smooth for cut surface, the notch portion quenching hardness is HRC42～47.
Claims (3)
1, a kind of straightener universal coupling, it is characterized in that two fixedly spindle nose (1) respectively each with movable spindle nose (4) and movable spindle nose (7) between be connected and be positioned with steel ball (2); Movable spindle nose (4), movable spindle nose (7) respectively with they between connecting axle (5) between each adopts and has key (3) to be connected the location with holding screw (8); Back-up ring (6) axial location is in connecting axle (5).
2, straightener universal coupling according to claim 1 is characterized in that the incision end face all spherical in shape of movable spindle nose (4) and movable spindle nose (7).
3, straightener universal coupling according to claim 1 is characterized in that steel ball (2) is installed in the end recesses of fixing spindle nose (1).
