Embodiment Construction

[0065] figure 1 A schematic longitudinal section through a known toothed belt 1 is shown. The toothed belt 1 has a belt body 10 which extends substantially in the longitudinal direction X and consists of polyurethane (PU) as flexible material. In the flexible material of the belt body 10, a plurality of tension members 13 are arranged in the longitudinal direction X so as to extend parallel to each other in the transverse direction. Each tension member 13 is substantially embedded in and substantially completely surrounded by the flexible material of the belt body 10 . The steel cable 13 serves as the tension member 13 .

[0066] The toothed belt 1 has a drive side 11 and an outer side 12 facing away from the drive side in the vertical direction Z. Alternating teeth 14 and tooth grooves 15 in the longitudinal direction X are formed on the drive side 11 , which is why the drive side 11 can also be referred to as the toothed side 11 .

[0067] During the production of this k...

Abstract

The invention relates to a toothed belt (1) having a belt body (10) extending substantially in a longitudinal direction (X) and comprising a flexible material, in which at least one tension member (13), preferably a plurality of tension members (13), is at least substantially embedded in the flexible material of the belt body (10) in the longitudinal direction (X) and is at least substantially surrounded by the flexible material of the belt body (10), wherein the belt body (10) has a tooth-shaped side (11) with teeth (14) and tooth spaces (15), which alternate in the longitudinal direction (X). The toothed belt (1) is characterized in that the minimum thickness (a) of the flexible material of the belt body (10) on the tension member (13) of at least one tooth groove (15), preferably all tooth grooves (15), in the vertical direction (Z) corresponds at least to the minimum thickness (h) of the flexible material of the belt body (10) on the tension member (13) in the vertical direction (Z), wherein the minimum thickness (h) is calculated according to the thickness (d) of the tension member (13) in the vertical direction (Z) and the material hardness (ShA) of the flexible material of the belt body (10) in Shore A: h = 3 * d / ShA.

Description

technical field [0001] The invention relates to a toothed belt according to the preamble of patent claim 1, a method for producing such a toothed belt according to patent claim 6, a method for producing such a toothed belt according to patent claim 10 toothed belt and a method of producing such a toothed belt according to patent claim 11. Background technique [0002] In drive technology, belts are used in various technical fields for force transmission. For force transmission, eg in internal combustion engines, the band can be configured as a flexible, endless, closed strip. However, it is also possible to use belts with two open ends, for example in elevator systems, in order to move the elevator car in height. [0003] Today, such belts are generally produced substantially as flexible belt bodies from flexible materials such as elastomeric materials (e.g. rubber) or such as plastics (e.g. polyurethane (abbreviated: PU), in flexible belt bodies , the tension members (fo...
