Abstract
For roller forming installation with the recuperation driving mechanism loadings in elements
of its design and the drive are calculated, dependences for definition of efforts in the connecting
rods necessary for reduction in back and forth motion of forming carts, and normal reactions of
guides of the movement of forming carts to the directing rollers depending on an angle of rotation
of cranks are received.
At a research of loadings the two-mass dynamic model of roller forming installation in
which power and power characteristics of the driving engine and each of forming carts, rigidity of
the driving mechanism and its dissipation are considered is used. Function of change of necessary
torque on driving to a shaft of cranks for ensuring process of consolidation of products of construction mixes taking into account dissipation of the driving mechanism is defined. Rated rated power
on which the electric motor is chosen is determined by average value of the moment of forces of
resistance for a cycle of turn of cranks, connecting couplings and a reducer are picked up. Using
Lagrange's equation of the second sort, for the roller forming installation with the recuperation drive
presented by two-mass dynamic model the differential equations of the movement are worked out.
As a result of a numerical experiment for roller forming installation with the recuperation
driving mechanism the value of the rigidity of the driving mechanism brought to an axis of rotation
of cranks at which the minimum loadings in couplings of the driving mechanism are observed is
defined. The dependence of the moment is installed in the drive coupling from the size of coefficient of dissipation and the recommended dissipation coefficient size for roller forming installation
with the recuperation driving mechanism is determined.
Influence of a corner of shift of cranks on dynamics of roller forming installation with the
recuperation driving mechanism is analyses.
