Abstract
The utility model relates to a belt wheel transmission system, which comprises a shell, a main shaft and a main shaft sleeve assembly, wherein the main shaft runs through the shell; a main shaft sleeve is arranged on the main shaft; the outer diameter of the front end of the main shaft sleeve is equal to the inner diameter of the main shaft hole on the right plane and is embedded in the main shaft hole on the right plant; the mid part of the main shaft sleeve is provided with a ring baffle part; the main shaft sleeve is chucked on the outer wall of the right plan; and the rear part of the main shaft sleeve is the part of belt transmission part that is connected to the belt so that the rotation of the main shaft sleeve drives the main shaft to rotate. The utility model simplifies the transmission system, improves precision of the transmission and reduces the production cost.
Description
Technical field:
The utility model relates to a kind of pulley drive system of needling equipment.
Technical background:
Original needling equipment adopts gear train assembly, its drive system structure as depicted in figs. 1 and 2, one main body is provided with a dividing plate in the main body, main body is divided into two cavitys, be designated as left cavity and right cavity, one main shaft is in main body, and a collar bush assembly is placed on main shaft one end, and this collar bush assembly front end is a gear, be embedded in the spindle hole of right side, the centre is provided with a card body, be placed in the collar bush assembly the right side outside on, be provided with an annular groove blocking on the body, one shift fork, its jaw is a semi-circle, and its internal diameter is identical with card body upper groove diameter, in holding and the groove, this shift fork handle end is provided with a through hole, is fixed on the right side by screw; Be provided with a gear in lower-left, inner main axis hole, right side, it is meshed with collar bush assembly front end gear, one transmission shaft, the one end is placed on this gear, run through dividing plate, in left cavity, be equipped with a helical gear on the end, on left cavity aft bulkhead, be provided with a cuboid projection, also be provided with a helical gear on it, it is meshed with helical gear on the transmission shaft, is provided with a small size motor on the protruding outer wall of cuboid, helical gear on this motor drives projection rotates, helical gear drives the helical gear that is meshed with it, drives two gears in the right side by drive link, rotates thereby drive main shaft; But this transmission system is owing to complex structure, and its transmission validity is not high, and the manufacture cost height.
Summary of the invention:
The utility model has mainly solved the not high problem of gear train assembly transmission validity, provides a kind of validity height, the pulley drive system that cost is low.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of pulley drive system, comprise casing, main shaft and collar bush assembly, described main shaft is in casing, one collar bush assembly, be placed on the main shaft, this collar bush assembly front end external diameter equates with spindle hole internal diameter on the right plane, be embedded in the spindle hole of right plane, be provided with an annular stop part in the middle of the collar bush assembly, the collar bush assembly is placed on the outer wall of right plane, collar bush assembly rear end part is the belt transmission position, is connected with belt; Thereby the rotation of described collar bush assembly drives the rotation of main shaft.
As a kind of preferred version of such scheme, in main shaft and the static connection of collar bush assembly, collar bush assembly and spindle hole are dynamically connected.
The utility model has been simplified transmission system, has not only improved the validity of transmission, and has reduced manufacture cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural scheme of mechanism of gear train assembly.
Fig. 2 is the A-A sectional view of gear train assembly Fig. 1.
Fig. 3 is a kind of perspective view of the utility model pulley drive system.
Fig. 4 is a kind of plane structure schematic representation of the utility model pulley drive system.
Embodiment:
According to Fig. 3 and shown in Figure 4, the utility model is by casing, and main shaft and collar bush assembly are formed.
It is one rectangular-shaped that described casing is, be provided with a dividing plate in the casing, on dividing plate and casing right side, respectively be provided with a spindle hole 1, one main shaft is in casing, one collar bush assembly 5, hollow tubular, be placed on main shaft 2 one ends, these collar bush assembly 5 its front end external diameters are the same with spindle hole 1 internal diameter, are embedded in the spindle hole 1, are provided with an annular snap body 3 in the middle of the collar bush assembly 5, on being placed in it outside right side, collar bush assembly 5 rear ends are the belt transmission position, are connected with belt on it, and the belt the other end is connected with a small size motor.This small size motor drives belt and rotates, thereby drives the collar bush assembly, realizes that main shaft rotates.
