Abstract
The utility model relates to a connecting mechanism for connecting a shaft and a hub. Wherein, a combined key is installed between a shaft (4) and a hub (1). The combined key comprises an arc wedge key (2) and a square wedge key (3). The utility model is characterized in that one bottom surface of the arc wedge key is cylindrical. The connecting mechanism is of simple structure, easy to install and disassemble, can effectively compensate any phase difference existing in the shaft and hub, so as to meet the requirement on consistency of main-shaft gears located at two sides of a crank press (for example honeycomb briquette machine) that is driven by two sides.
Description
Affiliated technical field
The utility model relates to the connecting structure of a kind of axle and wheel hub, especially the connecting structure that is connected with the phase place requirement of axle and wheel hub.
Background technique
Adopt the crank press of bilateral transmission, as briquetting machine, require: 1, the rotation phase of the mainshaft gear on its both sides must be consistent; 2, main shaft should not have the gap with connecting of mainshaft gear.For reaching this requirement, at present main shaft with mainly contain two kinds of schemes connecting of mainshaft gear.Scheme 1, main shaft adopts flat key to connect with the one or both ends of mainshaft gear, and this scheme requires the matching gap of main shaft and gear wheel hub very little, and therefore processing, assembling and maintenance are very difficult; Scheme 2, main shaft adopts tapered sleeve to connect with the one or both ends of mainshaft gear, and this scheme performance is good, but the cost height, and poor rigidity.
Summary of the invention
The utility model provides a kind of circular arc wedge key connection structure, this connecting structure effectively compensating shaft and wheel hub have a phase error, satisfy of the phase equalization requirement of the briquetting machine of bilateral transmission to the mainshaft gear on its both sides.
The technological scheme that its technical problem that solves the utility model adopts is: a Macintosh is installed between axle and wheel hub, and Macintosh comprises circular arc wedge key (2), square wedge key (3).One working surface of circular arc wedge key (2) is the inclined-plane, contacts with square wedge key (3), and another working surface is the cylndrical surface, contacts with wheel hub (1).Wheel hub also has corresponding cylndrical surface on (1).Because: 1, circular arc wedge key (2) is the inclined-plane with the fitting surface of square wedge key (3); 2, circular arc wedge key (2) is the cylndrical surface with the fitting surface of wheel hub (1); So: 1, axle (4) allows certain error with the circumferential phase place of wheel hub (1); 2, can eliminate gap between axle (4) and the wheel hub (1).
In the concrete enforcement, also can on axle (4), process the inclined-plane, cooperate, save square wedge key (3) with the inclined-plane of circular arc wedge key (2).
Of the present utility model simple in structure, easy processing, easy to maintenance, bearing capacity is strong, and cost is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model one embodiment's a structural drawing, double as specification digest accompanying drawing.
Fig. 2 is a figure I--I sectional drawing.
Fig. 3 is the connect situation of embodiment's axle when being 3 ° with the phase difference of wheel hub.
Fig. 4 is a circular arc wedge key stereogram.
Embodiment
Among the figure, 1. wheel hub, 2. circular arc wedge key, 3. square wedge key, 4. spool, 5. pressing plate, 6. screw.
Among Fig. 1, square wedge key (3) is contained on the axle (4), and circular arc wedge key (2) is contained between wheel hub (1) and the square wedge key (3); Screw (6) gives circular arc wedge key (2) certain precompression, prevents that circular arc wedge key (2) is loosening.
Among Fig. 3, when axle and wheel hub have phase difference the time, circular arc wedge key (2) cooperates still fine with wheel hub (1), square wedge key (3), can make corresponding compensation fully, simultaneously, the axial position of circular arc wedge key (2) also has corresponding variation, and this variation is regulated by screw (6).
Claims (1)
1. circular arc wedge key connection structure, comprise the circular arc wedge key and the square wedge key that are installed between axle and the wheel hub, one working surface of circular arc wedge key is the inclined-plane, contact with square wedge key, another working surface is the cylndrical surface, contact with wheel hub, corresponding cylndrical surface is also arranged on the wheel hub, it is characterized in that: include the circular arc wedge key.
