SU885035A1 - Centrifuge for moulding bodies of revolution of concrete mixes - Google Patents

Description

one

This invention relates to the manufacture of products from concrete mixtures and may be. used to produce rotary bodies, e.g. pipes.

Closest to the invention is a roller centrifuge containing a form with bandages, driving and idle rollers (1.

However, this centrifuge is very energy intensive and drive unreliable.

The purpose of the invention is to increase the reliability and reduce the energy intensity of the centrifuge drive.

This goal is achieved by the fact that a centrifuge for forming rotation bodies from concrete mixes, containing base bearings sealed in pairs and symmetrically arranged drive and idler rollers with flanges, in contact with form bands, is fitted with foot rests and horizontal guides fixed on the base, and bearings placed in guides and spring-loaded relative to the stops.

FIG. 1 schematically depicts a centrifugal fugus for forming rotation bodies, a common

view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

A centrifuge for forming rotation bodies from concrete mixes consists of a base 1 with drive 3 installed in bearings 2 and idle (not shown) rollers with flanges 4 in contact with shields 5 of form 6.

The base 1 is provided with abutments 7 fixed thereto and guides 8 in which the bearings 2 are located, which are spring-loaded with elastic elements 9.

The shaft 10 of the drive rollers 3 is connected by a gear coupling 11 with the shaft 12 mounted in stationary bearings 13 and driven in rotation from the belt drive 14.

The centrifuge works as follows.

Form 6 using tires 5 is mounted on drive 3 and idle rollers. From the belt drive 14, through the shaft 12, the gear coupling 11 and the shaft 10, the torque is transmitted to the drive roller 3.

Due to the irregularities of the end surfaces of the tires 5 and the flanges 4, the drive; The rollers 3 experience an axial inertia force, which decreases as the drive roller moves along its axis of rotation. In this case, the bearings 2 move along the guides 8, acting on the elastic elements 9. As a result of a decrease in the axial force between the bands and the flange Mti, the frictional forces between them decrease.

The use of the proposed centrifuge will increase the reliability and reduce the energy intensity of its drive.
