Abstract
The invention provides a positioning mechanism for a belt pulley and a mechanism manufacturing method. The mechanism is characterized in that a triangular belt is mounted on the belt pulley; a key is mounted on a main shaft and the belt pulley; a cylindrical head of a slotted long cylinder end fastening screw is tightly propped into a circular hole in the key; a slotted flat-end fastening screw is tightly propped to the slotted long cylinder end fastening screw. The method comprises the following steps: 1, fixing the belt pulley into a V-shaped groove through an outer circle of the belt pulley; 2, drilling bottom holes for mounting threads in the bottom part of a slot in the belt pulley and a hub through a drill bit with a lengthened handle; 3, expanding the hole of the slot in the pulley wheel through a hole expanding drill bit; 4, mounting screw holes in a tapping manner; 5, mounting the belt pulley on the main shaft, and drilling a hole used for mounting the cylindrical head of the slotted long cylinder end fastening screw through a drill bit; 6, tightly propping the cylindrical head of the slotted long cylinder end fastening screw into the circular hole in the key, and tightly propping the slotted flat-end fastening screw on the slotted long cylinder end fastening screw. The positioning mechanism and the method can overcome the shortages in the prior art. The belt pulley can be quickly, accurately and reliably fixed to a shaft through the positioning mechanism.
Description
Art
The present invention relates to engineering goods parts, especially belt pulley detent mechanism.
Background technology
It is the common structure of mechanical part that belt pulley is arranged on axle by key, and the axial location of belt pulley on axle is generally with spacer, shaft end ring location.And some situations can not realize, as hollow shaft etc.
Summary of the invention
The object of the invention is the defect overcoming prior art, a kind of belt pulley detent mechanism is provided, fast, accurately, reliably belt pulley can be fixed on axle.
The object of the invention is to realize as follows:
Over pulleys carried, key is contained in the keyway of main shaft and belt pulley V-belt dress, and the socket cap of oval styletable holding screw of slotting holds out against in the circular hole of key, and fluting flush end holding screw holds out against on the oval styletable holding screw of fluting.
Belt pulley detent mechanism preparation method is: 1) be fixed in V-type groove by the cylindrical of belt pulley belt pulley; 2., with the drill bit being welded with lengthening handle, the bottom and wheel hub of the groove of belt pulley are bored the bottom outlet installing screw thread; 3. with the hole having the reaming bit of guiding to expand the groove of belt pulley; 4. screw tap is contained on specific purpose tool, attacks installation screw; 5. belt pulley is arranged on main shaft, the hole of the socket cap of the oval styletable holding screw of fluting is installed by bit drills; 6. the socket cap of the oval styletable holding screw of fluting is held out against in the circular hole of key, fluting flush end holding screw holds out against on the oval styletable holding screw of fluting.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing is the structure chart of belt pulley detent mechanism.
1. belt pulleys, 2. key, 3. V-belt in figure, oval styletable holding screw of 4. slotting, flush end holding screw of 5. slotting, 6. main shaft.
Detailed description of the invention
With reference to accompanying drawing, a kind of belt pulley detent mechanism, is made up of belt pulley (1), key (2), V-belt (3), oval styletable holding screw (4) of slotting, fluting flush end holding screw (5) and main shaft (6); V-belt (3) is contained on belt pulley (1), and key (2) is contained in transmitting torque in the keyway of main shaft (6) and belt pulley (1); The socket cap of oval styletable holding screw (4) of slotting holds out against, in the circular hole of key (2), belt pulley (1) is fixed on main shaft (6), realizes axial location; Fluting flush end holding screw (5) holds out against and prevents from loosening on the oval styletable holding screw (4) of fluting.
Belt pulley detent mechanism preparation method is: 1) be fixed in V-type groove by the cylindrical of belt pulley (1) with belt pulley (1), makes bit rotational axis on the intersection of V-type groove longitudinal median plane and transverse center plane; 2., with the drill bit being welded with lengthening handle be clipped on drilling machine, the bottom and wheel hub of the groove of belt pulley (1) are bored the bottom outlet installing screw thread; 3. with the hole having the reaming bit of guiding to expand the groove of belt pulley (1), because the aperture expanded is on the inclined-plane of the groove of belt pulley (1), the hole guiding of boring by preorder; 4. screw tap is contained on specific purpose tool, the cylindrical of specific purpose tool should be able in reaming above flexible rotating, attack installation screw with screw tap; 5. belt pulley (1) is arranged on main shaft (6) by key (2), if desired first with originally boring the drill bit of thread Pilot hole at the upper countersinking of key (2), in the hole of the socket cap with the oval styletable holding screw (4) of flat bit drills installation fluting; 6. the socket cap of the oval styletable holding screw (4) of fluting is held out against in the circular hole of key (2), fluting flush end holding screw (5) holds out against on the oval styletable holding screw (4) of fluting, prevents from loosening.
Claims (2)
