Abstract
The ball joint-piston type universal coupling for the application of small radius of gyration, great torque and small gyration inertia includes mainly two ball joint coupling discs, two ball joint knuckle bearings and one piston cylinder. The ball joint coupling discs are mounted on two ends and have several holes; the ball joint knuckle bearings are mounted inside the holes in the ball joint coupling discs; and the piston cylinder is mounted to the inner circle of the ball joint knuckle bearings. The present invention realizes the universal torque transmission via force transmission in the said parts, and the ball joint-piston type universal coupling may be used in various equipment in metallurgy, mining, petrochemical and other industry.
Description
Technical field the present invention relates to a kind of small swing radius, high pulling torque and little ball pivot piston type Hooks coupling universal coupling of revolution inertia of being applicable to, is the indispensable equipment of common engineering, belongs to the F16D1/00 class.
The employed in the prior art Hooks coupling universal coupling of background technique mainly contains crosshead coupling, Rzeppa type Hooks coupling universal coupling etc., they can both play the effect of universal transmitting torque, but deficiency poor, the in service inertia additional load that is complex structure, concentricity is big, cost is high.
Summary of the invention the object of the present invention is to provide a kind of structure comparatively simple, can be used for the ball pivot piston type Hooks coupling universal coupling on the turning radius is little, transmitting torque the is big industry equipment.
For achieving the above object, the technical solution adopted in the present invention is: make earlier two ball pivot tray joint shafts, be processed with the hole of circular hole or other shape on the circumference that on this ball pivot tray joint shaft with the radius is R, the ball pivot joint shaft bearing is installed in each hole.Form the piston cylinder that stretchability is arranged by piston rod and piston cylinder cylinder body, and the afterbody axle of piston cylinder cylinder body and the piston rod of piston cylinder go out axle head respectively with two ends ball pivot tray joint shaft in the endoporus close fit of ball pivot joint shaft bearing, between piston rod and piston cylinder cylinder body, also be equipped with lining simultaneously.
The ball pivot piston type Hooks coupling universal coupling that adopts as above technological scheme to make compared with prior art has the following advantages: simple in structure, easy to manufacture, easy to maintenance, cost is low, the turning radius is little, transmitting torque is big, concentricity is good, inertia is little, the operation additional load is little, has a good application prospect.
Description of drawings
Fig. 1 is a ball pivot piston type universal joint structure cross-sectional schematic of the present invention, also is specification digest accompanying drawing of the present invention.
Fig. 2 looks schematic representation for the left side of ball pivot piston type Hooks coupling universal coupling shown in Figure 1.
Embodiment is described in further detail the specific embodiment of the present invention below in conjunction with drawings and Examples.
As shown in drawings, 1 or 1 ' be the ball pivot tray joint shaft, 2 is piston rod, 3 is the piston cylinder cylinder body, 4 is lining, 5 or 5 ' be the ball pivot joint shaft bearing, 6 or 6 ' for be distributed in ball pivot tray joint shaft 1 or 1 ' on the hole, this hole can be the hole of circular hole or other shape, with O be the center of circle, R be radius ball pivot tray joint shaft 1 or 1 ' circumference on each hole 6 of distributing or 6 ' internal fixation be equipped with ball pivot joint shaft bearing 5 or 5 '.Piston rod 2 consists of the piston cylinder with stretchability effect with piston cylinder cylinder body 3, the afterbody axle of each piston cylinder cylinder body 3 and the endoporus close fit of the ball pivot joint shaft bearing 5 on the ball pivot tray joint shaft 1, and the piston rod 2 of each piston cylinder go out axle head and ball pivot tray joint shaft 1 ' on ball pivot joint shaft bearing 5 ' the endoporus close fit.Piston rod 2 and piston cylinder cylinder body 3 are for movingly.The endoporus of piston cylinder cylinder body 3 is cylndrical surface or non-cylndrical surface, and with piston cylinder cylinder body 3 endoporus mutually movingly the fitting surface of piston rod 2 also be cylndrical surface or non-cylndrical surface.Lining 4 closely is sleeved on the inwall of piston cylinder cylinder body 3.
When being applied to as above ball pivot piston type Hooks coupling universal coupling on the required industry equipment, each the ball pivot joint shaft bearing (as 5) that is loaded in the hole 6 is given in ball pivot tray joint shaft 1 power transmission of one end, each ball pivot joint shaft bearing 5 is passed to power the corresponding piston cylinder respectively, each piston cylinder power transmission is again given corresponding each ball pivot joint shaft bearing of the other end (as 5 '), the ball pivot tray joint shaft (as 1 ') of the other end is given in last each ball pivot joint shaft bearing (as 5 ') power transmission, thereby realizes the purpose of carry-over moment.Each ball pivot tray joint shaft 1 or 1 ' universal property be to realize by the universal property of each the ball pivot joint shaft bearing on this ball pivot tray joint shaft, and the piston cylinder that connects with each ball pivot joint shaft bearing has stretchability, eliminated the constraint on the line of centres on two ball pivot tray joint shafts that are connected in piston cylinder, make two ball pivot tray joint shafts (as 1 and 1 ') all have the function that can both turn an angle in any direction, so just can realize that ball pivot piston type Hooks coupling universal coupling of the present invention has the purpose of universal transmitting torque effect.
In addition to the implementation, other embodiments of the present invention are:
The afterbody axle of piston cylinder cylinder body 3 and ball pivot tray joint shaft 1 ' on ball pivot joint shaft bearing 5 ' the endoporus close fit, and the endoporus close fit that goes out the ball pivot joint shaft bearing 5 on axle head and the ball pivot tray joint shaft 1 of the piston rod 2 of piston cylinder; Or the afterbody axle, go out the staggered assembling of endoporus on the ball pivot joint shaft bearing on axle head and the ball pivot tray joint shaft.
On the inwall of piston cylinder cylinder body 3, the suit lining 4.
Ball pivot joint shaft bearing 5 or 5 ' can adopt the joint ball journal, selfaligning bearing or ball pivot.
