Abstract

In a conveyor drive unit of the type where the main conveyor chain 1 is in driving engagement with an auxiliary chain driven by a prime mover, the respective casings (2,5) of the auxiliary chain and of the prime mover are connected by a torsion spring (6) to permit the casing (5) of the prime mover to be angularly displaced about an axis that coincides with the axis of rotation of the sprocket wheel (4) of the auxiliary chain. The sprocket wheel (4) is preferably mounted on a common shaft (7) with a worm wheel 8 meshing with a worm (9) driven by the prime mover. <IMAGE>

Description

(54) DRIVE OF SUSPENDED CHAIN CONVEYOR

The invention relates to drive devices, in particular, overhead chain conveyors. The drive unit has an auxiliary circuit that interacts with the conveyor chain. The known drive of the suspension chain conveyor} contains the envelope of the drive and tension sprocket, an auxiliary circuit, an auxiliary circuit drive with a drive element 1. The closest technical solution known is the drive of an overhead chain conveyor containing an auxiliary circuit located in the housing, the drive and tension sprocket mounted on the axles for the chain and the drive element of the auxiliary chain drive 2. The disadvantage of the specified conveyor drives is as follows. s point between auxiliary drive element and the drive chain drive sprocket axle, which results in the appearance of significant dynamic loads on an auxiliary circuit, causing its irregular movement. As a result, the overhead chain conveyor drive is unreliable. The aim of the invention is to increase the reliability of the drive. This goal is achieved by the fact that the drive element is fixed on the housing by means of a torsion spring, wherein the axis of the drive sprocket is made hollow, and inside it is a torsion spring. FIG. 1 shows a general view of the drive; in fig. 2 - section aa on figo1. The drive is housed in housing 1. The conveyor circuit 2 passing through the housing interacts with the drive rollers of the auxiliary circuit 3 through its rollers, which passes through the housing 1 and bends around the drive and tension sprocket 4. The drive sprocket 4 together with the worm gear 5 of the drive element are mounted on the hollow chain axis 6. In the drive element, the worm gear 5 interacts with the screw 1, driven by the motor shaft or through a V-belt drive, which are mounted on the casing 8. The drive housing 8 to Repits on the housing of the actuator 1 through the torsion spring 9, allowing turning or tightening the casing 8 relative to the housing 1. The torsion spring 9 is placed inside the hollow axis b,

The device works as follows.

The chain conveyor 2 is moved by an auxiliary chain 3, which is installed in the housing 1. The housing 1 is mounted together with the conveyor belt. Auxiliary chain 3 is moved by an asterisk 4 mounted on a hollow axis b. A torsional moment acts on the hollow axis b due to the drive of the auxiliary chain. The casing 8 of the drive element will tend to rotate around the hollow axis b when the screw auger 7 is rotated on the casing B.

The casing 8 of the drive element is connected by a torsion spring 9 to the body 2. The twisting of the torsion spring 9 is proportional to the resulting torsion moment.
