Description

I

The invention relates to equipment for testing machines and mechanisms, namely, a test bench for lubricating devices for conveyor hinge linkage lubricants.

The aim of the invention is to reduce the size and material consumption.

FIG. I schematically shows the stand of the placement side of the lubricant device under test, general view; in fig. 2 shows section A-A in FIG. I.

The bench contains 2 dp of fixing the tested device 3 lubricants, gear 4 with the high speed 5 and low speed 6 shafts mounted on the base I, and the electric motor 7 connected with the belt transmission 8 to the high speed shaft 5 gear 4. low-speed shaft 6 is rigidly fixed leading sprocket 9, and on the high-speed shaft 5 of the gearbox 4 is movably mounted by bearings 10 with the knowledge of asterisk II, with the leading 9 and the driven 11 having stars placed from the side of the tested lubrication device 3. Between the sprocket I1 and the high-speed shaft 5, the elastic sleeve 12, for example, made of reinforced rubber, is installed. The drive 9 and the sprocket 1I sprockets are interconnected by a pull chain 13, the hinges 4 of one of the branches of which are installed with the possibility of interaction with the tested lubrication device 3. At site 2, a device dp supporting hinges 14 tons of bend chain 13, made in the form of a hammer line 15, is placed.

The stand works as follows.

Rotation of the electric motor 7 - through a belt drive 8 re150121:

given to high-speed 5 and low-speed 6 shafts of the gearbox 4 and further to the drive 9 and driven sprockets I1.: T 13 chain with hinges 14

5 is set in motion. The ruler 15, interacting with the hinges 14 of the chain 13, provides the exact trajectory of their movement relative to the platform 2, and

10 therefore, with respect to the lubricant 3 tested on the platform 2.

Claims (3)

Invention Formula I. Stand dp testing the lubrication devices of the hinges of the conveyor chain, containing a base-mounted drive with an electric motor and a gearbox with the ends of the high-speed and low-speed shafts extended through the housing, a platform fixed on the base for mounting the tested device on it lubricants, both driven and driving sprockets, kinematically connected to a gearbox and connected between-cq-battle by an infinitely closed traction chain, located one of the branches opposite the tested lubrication device, characterized in that, in order to reduce overall dimensions and material intensity, the sprocket is hard zakre35 captivity at the end of the low-speed shaft gearbox, and the knowledge is set using bearings at the end of the high-speed shaft of the gearbox. 2. The stand according to clause I, clause 1 and 40 is determined by the fact that the sprocket is mounted on bearings using an elastic sleeve. 3. A stand according to claim I, characterized in that the resilient sleeve is made of reinforced rubber. 73 4-4 Fi.2
