Abstract
The utility model discloses a connecting device of a shaft and a hub. A guide ring which is formed by an inner ring and an outer ring is arranged between the shaft and the hub, and more than four wedge-shaped locking devices are arranged evenly all around the guide ring. The wedge-shaped locking device is formed by a left wedge-shaped block, a right wedge-shaped block and an inside hexagonal bolt, the left wedge-shaped block and the right wedge-shaped block which are arranged oppositely can move in opposite direction simultaneously inside a locker by screwing the inside hexagonal bolt, certain radial force can be produced on the two halves of the inner ring and the outer ring of the guide ring, the evenly distributed stable locking pressure forms a friction connection, so that the shaft and the hub are locked tightly with each other. When a fastening device needs to be dismantled or regulated, the shaft and the hub can be unloosed only by unscrewing the bolts.
Description
Technical field
The utility model relates to a kind of mechanical structure, particularly a kind of axle and wheel hub connection.
Background technique
The band transmission is a kind of form commonly used in the mechanical transmission, belt wheel with spool connect the gap fiting mode that adopts key connecting mostly.But this, Placement but was difficult to satisfy the demand to large-scale, high quantity delivered belt comveyer in week, and the high tenacity travelling belt must have high tractive force, must have the firm performance that connects between cylinder and the axle.During with usual manner assembling cylinder.Problem of ubiquity, promptly because the wheel hub pressurized is uneven, wheel hub will " play " on axle in operation process, thereby causes belt deviation, and then causes belt and bearing premature damage.This phenomenon is even more serious to wide and the performance of highi degree of accuracy cylinder.The utility model has designed a kind of new belt wheel and the connecting mode of axle for this reason, and it preferably resolves the problems referred to above, and structure is unique, and the installation and removal belt wheel is very convenient, has good practical values.
The model utility content
The purpose of the utility model provides a kind of simple and shaft-hub function admirable connects securing means, and as shown in Figure 1, it is the ring wedge mechanism of one group of non-self-locking, and its working principle designs according to wedge effect.
Between axle 1 and wheel hub 3, the first lead ring 2 that constitutes by interior ring 7 and outer shroud 4 of packing into, the formerly even all around wedge lock mechanism (as shown in Figure 2) that distributes more than four of lead ring 2.Wedge lock mechanism is made up of right wedge-shaped blocks 5, left wedge-shaped blocks 6 and hexagon socket head cap screw 8; The hexagon socket head cap screw 8 of screwing just can make right wedge-shaped blocks 5 and left wedge-shaped blocks 6 move in opposite directions; According to known cylinder physical dimension, torque M and given friction factor; Can calculate in the first lead ring of two halves the radial force that produces on ring 7 and the first lead ring outer shroud 4, axle and roller hub are locked each other.
The axle of this structure and wheel hub connection adopt torque wrench to provide definite locking torque as required, and locking device just adjusted the position when mounted, need not to have reduced maintenance load because of preventing to become flexible shutdown inspection.The axle and the locking task of wheel hub can be accomplished, and " play " between the two can be eliminated.
Compared with prior art, simple in structure, easy for installation, increase work efficiency.
Description of drawings
Fig. 1 is axle and wheel hub connection schematic representation;
Fig. 2 is the structure and the fundamental diagram of axle and wheel hub connection;
1, axle, 2, first lead ring, 3, wheel hub, 4, outer shroud, 5, right wedge-shaped blocks, 6, left wedge-shaped blocks, 7, interior ring, 8, hexagon socket head cap screw.
Embodiment
At first first lead ring 2 is placed between axle 1 and the roller hub 3; When using torque wrench; When tightening hexagon socket head cap screw 8 with torque M, two left wedge-shaped blockss 6, right wedge-shaped blockss 5 relative to configuration move in locking device simultaneously in opposite directions, and do not relatively move between this moment spool 1 and the wheel hub 3.Can in the first lead ring of two halves, encircle 7 with outer shroud 4 on produce certain radial force, axle 1 and wheel hub 3 are locked each other.These equally distributed stable locking pressure have just formed friction and have connected.When needs are dismantled or adjusted this securing means, only need unscrew hexagon socket head cap screw 8 and can throw off.
Claims (2)
1. axle and wheel hub connection is characterized in that: between axle and roller hub, the first lead ring that constitutes by interior ring and outer shroud of packing into, formerly lead ring around the even wedge lock mechanism of distribution more than four.
2. a kind of axle according to claim 1 and wheel hub connection is characterized in that described wedge lock mechanism is made up of left and right two wedge-shaped blockss and hexagon socket head cap screw, and the hexagon socket head cap screw of screwing just can make right wedge-shaped blocks and left wedge-shaped blocks move in opposite directions.
