Abstract
The utility model discloses a fork-type universal ball bearing coupling for connecting the transmission component in mental pressure processing flow. An active driving fork 1 is assembled opposite to the driven fork 2. On the driving fork 1 of a clearance 6 and corresponding plane of a driven 2 are provided with a roll path 4 which can lay the sphere or a waist drum-shaped rolling body 3. Around the rolling body 3 and on the roll path 4 are fixed with a baffle 5 for turning back the rolling body 3. When in use, it is necessary to connect the driving fork 1 to the main shaft of the power source and the driven fork 2 to the main shaft of the operation working component. The power (quadrate) of the driving fork 1 is transmitted to the driven fork 2 via rolling body 3 severing as a universal coupling. The osculation stress between the rolling body 3 and roll path 4 of the coupling is distributed evenly, thus, the bearing capacity could be enhanced. The rolling friction between the two parts can prolong the service life of the coupling with reasonable structure, high reliability and promotion value.
Description
Technical field
The utility model relates to a kind of coupling, relates in particular to a kind of universal ball coupling of fork head type that the stress metal processing technology connects driving component that is used for, and belongs to the F16D3/221 class.
Background technique
Being applied to stress metal processing technology or other has the coupling that connects in the driving component technological process, and its structure and shape are in different poses and with different expressions, its characteristic respectively, and they are bringing into play effect separately on distinct device.Had the patent No. to be before the utility model: ZL99233444.6 " a kind of ball coupling ", ZL03227507.2 " ball pivot piston type Hooks coupling universal coupling ", ZL03227574.9 " the anti-elementary errors radius of curvature of shock resistance ball coupling " and ZL200520050333.1 " universal ball coupling " etc. are one of representatives, but, replaced by the ball coupling of new structure gradually because all there is defective in various degree in they.
Summary of the invention
In order to solve the technical problem that prior art exists, the utility model provide a kind of simple in structure, bearing capacity big, long service life, the universal ball coupling of fork head type easy to maintenance and economical operation.
For achieving the above object, the technical solution adopted in the utility model is: the driven jaw that the universal ball shaft coupling of a kind of fork head type described in the utility model is equated with number by the individual active jaw of N (integer of N＞1), a 2N rolling element, a 4N raceway and the baffle plate that equates with the raceway number are formed.Initiatively jaw and driven jaw are installed in opposite directions, initiatively between jaw and the driven jaw opposite planar is arranged, leave the gap between the plane, on the opposite planar of active jaw and driven jaw, be processed with raceway or raceway is installed, on raceway, be equipped with rolling element, adjacent rolling element blocks raceway with baffle plate in the gap between active jaw and driven jaw opposite planar, rolling element is suffered restraints in raceway unlikelyly arbitrarily run.Rolling element does to connect the effect of active jaw and driven jaw again, makes it into as a whole.In the coupling running, initiatively jaw (or driven jaw) passes to driven jaw (or active jaw) by the squeezing roll kinetoplast with power (square).Owing to initiatively leave the gap between jaw and the driven jaw opposite planar, driven jaw is all turned in all directions, realize universal function.
The universal ball coupling of a kind of fork head type that adopts as above technological scheme to provide, compared with prior art its beneficial effect is:
1. bearing capacity is big.Because what rolling element adopted is the bigger ball of physical dimension, between rolling element and the raceway excellent contact is arranged, distribution of contact is even, and bearing capacity can be carried 1-2 doubly.
2. long service life.The critical piece of this coupling is jaw and rolling element, used Material Strength height, and good mechanical property is rolling friction between rolling element and the raceway, but not sliding friction, it is little to wear and tear to each other, and can improve 30-50% working life.
3. simple in structure.The critical piece of described coupling only is jaw and rolling element, compares with cross universal coupling and has saved cross axle, and overall structure is optimized, and is easy to assembling.
4. easy to maintenance, economical operation, reduction operating cost 20-40%.
5. used zero one is a standard piece, little relative movement between them, and fault is few, and is reliable.
