The invention relates to mechanical engineering, in particular to trapezoidal section drive belts, used in belt drives with V-shaped pulleys.
A trapezoidal drive belt is known for use on V-shaped pulleys, which comprises an endless carrier in the form of a metal tape and transverse elements in the form of a trapezoidal plate, mounted close to each other with the possibility. sliding on an endless carrier, wherein said transverse elements are made with bevels on one of the end surfaces and are installed with their bevels in the direction of bending of the belt with the ability to interact with each other when bending the belt along the line of inclination formed by the intersection of the bevel surface with one of the parallel end surfaces and are interconnected by means of at least one protrusion on the end surface of one plate and a counter depression on the end surface facing it. plate offset from the line of inclination of the transverse elements of the belt towards its outer surface 1J.
The disadvantage of this belt is that with inaccurate installation of pulleys it is possible to twist it due to the fact that the transverse elements are constantly in mutual engagement.
The purpose of the invention is the expansion of operational capabilities.
This goal is achieved by the fact that in a trapezoidal drive belt for use on V-shaped pulleys, containing an endless carrier in the form of a metal tape and transverse elements in the form of trapezoidal plates mounted close to each other with the possibility of sliding on an endless carrier. These transverse elements are made with bevels on one of the end surfaces and are set with their bevels in the direction of bending the belt with the ability to interact with one another when bending the re n inclination of the line formed by the intersection of the chamfer with poverhiosti one of the parallel end faces
and interconnected by means of at least one protrusion on the end surface of one plate and the counter depression on the end surface of the other plate facing it, displaced relative to the line of inclination of the transverse elements of the belt toward its outer surface, the distance between the line of inclination and the protrusions ( pits) and the thickness of the transverse element are related by
bcJ 3,
where b is the distance between the line
slope and protrusions (recesses), mm;
c is the thickness of the transverse element, mm.
FIG. 1 shows a transverse element, an embodiment with one side slot for an endless carrier; in fig. 2 - the same, side view; in fig. 3 is a transverse element, an embodiment with two slits; in fig. 4 - the same, side view; in fig. 5 is a transverse element, an embodiment with one central slot; in fig. 6 - the same, side view.
The front drive belt contains an endless carrier in the form of a metal tape and transverse elements mounted close to each other with the possibility of sliding on an endless carrier. Each transverse element 1 is made in the form
trapezoidal plates with a bevel 2 and a protrusion 3 on one of the end surfaces and a recess 4 corresponding to the said protrusion and located on the opposite
5 end surface The transverse elements 1 are installed on an endless basis with their bevels in the direction of bending the belt and interact with each other when bending the belt along the inclination line 5, which is formed by the intersection of the bevel 2 surface with the end surface of the transverse element. The transverse elements are interconnected by means of a protrusion 3 on the end surface of one transverse element and the counter depression 4 on the reversed end surface of the adjacent transverse element. Projections 3 and recesses
