Abstract
The invention provides an anti-rotating mechanism for shaft ends, which consists of a clasping block 1 and a compressing sleeve 2, wherein the outside of the clasping block 1 is an outer cone; an inner hole of the clasping block 1 is polygonal; the clasping block 1 is divided into a plurality of equal parts; an inner hole of the compressing sleeve 2 is an inner conical hole; and the conical hole is matched with the outer cone of the clasping block 1. Four equal parts of the clasping block firmly clasp a polygonal shaft by utilizing the wedging force of conical surfaces, and static friction force produced between the conical surfaces ensures that the polygonal shaft cannot rotate. The mechanism has the characteristics of simple structure, low manufacturing cost, convenient assembly and reliable locking.
Description
Technical field
The present invention is used for the mechanism that the plastics machinery industry prevents that polygon axle from rotating.
Technical background
The connected mode of the machine barrel of double screw extruder and distributor box has a kind of by locking at eccentric dead point at present, the camshaft end mill becomes polygon, during clamping, fastening the polygon place with spanner forwards camshaft to dead-centre position and just can lock machine barrel, but do not overlap fully owing to clamping position in actual applications with the dead point, the vibration that the machine operation produces, the influence of series of factors such as eccentric wheel wearing clearance increase, camshaft is rotated under the effect of machine barrel at extrusion pressure, this can cause machine barrel and distributor box to unclamp, the screw rod fracture appears, machine barrel damages, even accident occurs.
Summary of the invention
The purpose of this invention is to provide a kind of rotation that prevents camshaft inoperative needs under locking state, avoid occurring accidents such as screw rod fracture, machine barrel damage.
Specifically, a kind of axle end rotation-proof mechanism of the present invention, by hold piece 1 tightly, clamping sleeve 2 is formed.
Advantage of the present invention and effect: a kind of axle end rotation-proof mechanism of the present invention is simple in structure, low cost of manufacture, easy to assembly, reliable lock.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is A-A figure of the present invention.
Fig. 3 is bindiny mechanism's schematic diagram of machine barrel and distributor box.
The specific embodiment
Accompanying drawing 1, Fig. 2, provided the specific embodiment of the present invention, a kind of axle end rotation-proof mechanism, by holding piece 1 tightly, clamping sleeve 2 is formed, as shown in Figure 1, the outside of holding piece 1 tightly is an outer cone, endoporus is a polygon, and this polygonal shape will meet the polygonal shape of axle head, as shown in Figure 2, hold piece 1 tightly and be slit into some equal portions, clamping sleeve 2 outsides are a cylinder, and endoporus is a female cone hole, and this conical bore matches with the outer cone of holding piece 1 tightly, clamping sleeve 2 entangles and holds piece 1 tightly during work, hold piece 1 tightly and hold polygon axle tightly, utilize bolt that clamping sleeve 2 is tightly compressed and hold piece 1 tightly, some equal portions of holding piece tightly move to axis direction under the effect of the conical surface, thereby hug polygon axle, at the stiction that produces between the conical surface under the effect of bolt thrust, make clamping sleeve 2 and hold piece 1 tightly and can not rotate, so polygon axle also just can't rotate.
Effect of the present invention:
The present invention is simple in structure, low cost of manufacture, easy to assembly, reliable lock.
