Abstract
This utility model relates to a kind of rotating shaft transmission taper attachment means, including rotating shaft, drive plate, axis hole interconnective with rotating shaft it is shaped with on drive plate, the side of axis hole is shaped with pin-and-hole, this pin aperture centerline is mutually perpendicular to axis hole centrage, minimum range between pin aperture centerline and the axis hole center of circle, less than the radius of axis hole, mounting pin in pin-and-hole, rotating shaft is shaped with the translot cooperated with pin；Mainly pin uses wedge pin, and it is cleat planes that this wedge pin is connected side with rotating shaft, and the translot bottom surface in rotating shaft has the inclined-plane that the cleat planes with wedge pin cooperates；The big end of wedge pin is installed towards rotating shaft direction of rotation.Wedge pin between automatic wedging rotating shaft and drive plate when rotating shaft rotates, eliminates rotating shaft, fit-up gap between wedge pin and drive plate, low to the requirement on machining accuracy of wedge pin, axis hole, pin-and-hole and translot, passes that noise is little, transmission efficiency is high.It is applicable to the transmission joint between butterfly valve valve rod and butterfly plate, machine shaft and load and other rotary shaft and drive plate.
Description
Technical field
This utility model belongs to mechanical driving device.This utility model is applicable to butterfly valve valve rod and butterfly plate, motor
Transmission joint between rotating shaft and load and other rotary shaft and drive plate.
Background technology
At present, between the rotating shaft and load of the drive mechanisms such as butterfly valve valve rod and butterfly plate, machine shaft and load
Connection, general use flat key or straight pin to connect.Its major defect is flat key and keyway or straight pin and pin
Fit-up gap between hole directly affects transmission efficiency, increases drive noise, so existing bindiny mechanism is to even
The requirement on machining accuracy of fitting is the highest.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, it is provided that a kind of to connector processing essence
Degree requires rotating shaft transmission taper attachment means low, that transmission efficiency is high, drive noise is little.
The technical solution of the utility model includes rotating shaft, drive plate, drive plate is shaped with and is connected with each other with rotating shaft
Axis hole, the side of axis hole is shaped with pin-and-hole, and this pin aperture centerline is mutually perpendicular to axis hole centrage, in pin-and-hole
Minimum range between heart line and the axis hole center of circle, less than the radius of axis hole, mounting pin in pin-and-hole, rotating shaft is shaped with
The translot cooperated with pin；Mainly pin uses wedge pin, and it is wedge shape that this wedge pin is connected side with rotating shaft
Plane, the translot bottom surface in rotating shaft has the inclined-plane that the cleat planes with wedge pin cooperates；Wedge pin
Big end is installed towards rotating shaft direction of rotation.
The utility model has the advantages that between rotating shaft with drive plate use wedge pin be connected, wedge pin hold greatly court
Rotating shaft direction of rotation install, rotating shaft rotate time automatic wedging rotating shaft and drive plate between wedge pin, eliminate turn
Fit-up gap between axle, wedge pin and drive plate, the processing essence to wedge pin, axis hole, pin-and-hole and translot
Degree requires low, and noise is little, transmission efficiency is high for biography.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the profile in A-A direction in this utility model Fig. 1.
Detailed description of the invention
Rotating shaft transmission taper attachment means as shown in Figure 1, including rotating shaft 2, drive plate 3, on drive plate 3
Being shaped with axis hole interconnective with rotating shaft 2, the side of axis hole is shaped with pin-and-hole 4, this pin-and-hole 4 centrage and axis hole
Centrage is mutually perpendicular to, and the minimum range between pin-and-hole 4 centrage and the axis hole center of circle is less than the radius of axis hole,
Make between pin-and-hole 4 and axis hole, to form vertical passing through mutually to be connected, mounting pin 1 in pin-and-hole 4, rotating shaft 2 is shaped with and pin
1 translot cooperated；Pin 1 uses wedge pin, and it is cleat planes that this wedge pin is connected side with rotating shaft 2,
Translot bottom surface in rotating shaft 2 has the inclined-plane that the cleat planes with wedge pin cooperates；The big end of wedge pin
Install towards rotating shaft 2 direction of rotation, the wedge between automatic wedging rotating shaft 2 and drive plate 3 when rotating shaft 2 rotates
Shape pin, eliminates fit clearance.
