Abstract
The utility model discloses an eccentric pivot used for a spinning machine, and relates to a connecting piece arranged in a main shaft bearing in a spinning machine to drive a connecting rod bearing to move. The eccentric pivot (1) is an integrated part consisting of an eccentric wheel (2), steps (4) of an eccentric axis on the same axial line with the eccentric wheel, a bearing inner race connecting shaft (5), an installation groove of an axle bumper loop (6) and a connecting shaft (8) for a large belt pulley. The axial lines of the steps (4) of the eccentric axis, the bearing inner race connecting shaft (5), the installation groove of the axle bumper loop (6) and the connecting shaft (8) of the large belt pulley are normal to a vertical center line of the eccentric wheel (2), and intersect with the vertical center line of the eccentric wheel (2) on one side of the vertical center line of the eccentric wheel (2). Keyways (7) are provided on the connecting shaft of the large belt pulley (8); a central access hole (9) is provided on top of the connecting shaft of the large belt pulley (8). As the eccentric wheel is arranged inside a bearing of a connecting rod, the connecting rod of the spinning machine can operates stably.
Description
Technical field:
The utility model sand line machine relates to the connector that is installed on drivening rod bearing movable in the sand line mainshaft bearing with camshaft.
Background technology:
Motor main shaft drives big belt pulley by small belt pulley now, big belt pulley drives the bent axle motion, make movements and postures of actors moving linearly, because crankshaft rotating produces upper and lower vibration, in order to eliminate the vibration that causes owing to bent axle, so between big belt pulley and bearing cone, should design new bindiny mechanism, to eliminate the great vibrations that causes owing to bent axle.
Summary of the invention:
The purpose of this utility model provides a kind of sand line machine camshaft, and the eccentric wheel of this camshaft is installed in the bearing cone of connecting rod; The big belt pulley connecting axle of this camshaft band keyway is installed big belt pulley by flat key.
A kind of sand line machine camshaft, it is characterized in that camshaft (1) is by eccentric wheel (2) be in eccentric shaft step (4), bearing cone connecting axle (5), shaft retaining ring mounting groove (6), a big belt pulley connecting axle (8) on the axis part that forms a whole, the axis normal of eccentric shaft step (4), bearing cone connecting axle (5), shaft retaining ring mounting groove (6) and big belt pulley connecting axle (8) is in eccentric wheel (2) vertical center line, and intersects at eccentric wheel (2) vertical center line one side; On big belt pulley connecting axle (8), have keyway (7), have centre hole (9) on the top of big belt pulley connecting axle (8).
The utility model sand line machine is installed in the bearing cone of connecting rod with the eccentric wheel of camshaft; The eccentric wheel step is used for making between the angle bar seat of sand line machine and the connecting rod and keeps the certain clearance distance, and the bearing of angle bar seat is positioned; The bearing cone connecting axle is installed in the bearing cone of angle bar seat; The shaft retaining ring mounting groove is used for installing the elastic shaft back-up ring, to prevent to be installed in the bearing displacement on the bearing cone connecting axle; The big belt pulley connecting axle is connected with big belt pulley by the flat key in its keyway.
When motor rotates, then the small belt pulley on the motor output shaft drives big belt pulley deceleration rotation by belt, big belt pulley drives the big belt pulley connecting axle rotation of this sand line machine with camshaft by flat key, then the eccentric wheel drivening rod on the camshaft rotates reposefully, because in the bearing in the connecting rod some steel balls are arranged, can in accurate raceway, absorb vibration, thus can make the connecting rod smooth rotation, thus the drive connecting plate and the movements and postures of actors are made upper and lower steady rectilinear motion.
The utility model sand line machine with the advantage of camshaft is: because its eccentric wheel is installed in the bearing cone of connecting rod, can make the connecting rod of sand line machine make easy motion.
