Abstract
The present invention relates to bottom cloth of a toothed belt, which comprises a flat pattern type (2 type) and an oblique pattern type (3 type). The bottom cloth is made of domestic chinlon. In twisting process and a weaving process, proper process parameters are selected, and a grey cloth is shaped and arranged to ensure the required unidirectional elastic elongation. The parameters of elasticity, wear resistance, intensity, breaking elongation, etc. of the bottom cloth of the present invention can be suitable for being used for a long time. Compared with common home-made chinlon bottom cloth, the service lives of the 2 type bottom cloth and the 3 type bottom cloth of toothed belts are increased by 5 to 10 times.
Description
Cog belt and band gear meshing are applied to transferring power, have many advantages, and its range of application is increasingly extensive.
Present domestic mass-produced cog belt, its base fabric is generally selected cotton for use, polyester-mixed cotton cloth, nylon cloth etc., all fail to reach unidirectional elastic elongation and stretch wear-resisting requirement by force, with its base fabric, in the base fabric forming process as cog belt with extraordinary, owing to lack unidirectional elastic elongation, make base fabric can not cover the flank of tooth and profile of tooth moulding difficulty well, then with skeleton and rubber moulding the time, because of the base fabric flank profil is circular arc, the rubber that is through base fabric coats, so just be unable to undergo wearing and tearing, the very fast distortion of profile of tooth has influenced the correct engagement with gear, cause transmission not steady, and base fabric is not wear-resisting, easy fracture, and reduce service life greatly.See Fig. 1-1.Fig. 1-the 1st, the cog belt figure that common polyamide fibre base fabric is made.
The unidirectional elastic elongation requirement that the cog belt base fabric is special is meant when processing and forming, and base fabric will have the elastic elongation of 30-80% along the yarn of tooth belt direction, and the yarn that intersects with the tooth belt direction does not then need this elastic elongation.Abroad be (the speciallyying permit out hope openly referring to the clear 59-222639 of Japan) that the employing industry is made base fabric with the polyamide fibre textured filament, this base fabric selects for use requirement very high to raw material.
The objective of the invention is to manage to improve the unidirectional elastic extension of cog belt base fabric, make base fabric can cover the flank of tooth and avoid profile of tooth moulding difficulty well, thus make base fabric wear-resisting, reduce fracture and improve service life.
The object of the present invention is achieved like this: gear band base fabric of the present invention, it is characterized in that adopting 2/2 twill base fabric, warp thread is with 210 dawn/34 polyamide fibre 66 multifilament, weft yarn piece does not manifest the polyamide fibre 6 high-elastic textured filaments of elastic elongation with 140 dawn/36, be generally 0～8 twist with the fingers/centimetre through close 360/10 centimetres, 285/10 centimetres of filling densities.
The base fabric system of cog belt of the present invention selects domestic polyamide fibre raw material for use, by the extraordinary heat treatment typing arrangement of twisting process and grey cloth, guarantees desired unidirectional elastic elongation, makes the cog belt base fabric, can improve 5-10 its service life doubly.

Base fabric of the present invention is 2/2 twill-weave, warp thread is with 210 dawn/34 polyamide fibre 66 multifilament, for ease of being difficult for fluffing in the weaving process and producing broken end, add certain twist, be generally 4-6 twist with the fingers/centimetre, weft yarn piece does not manifest the polyamide fibre 6 high-elastic textured filaments of elastic elongation with 140 dawn/36, add 0～8 to twist with the fingers/centimetre; In weaving process, suitably reduce the tension force and reducing of beating up, the weft yarn that is subjected to when weaving beating up tension force and extends is shunk under the nature recovering through close; Base fabric through close be 360/10 centimetres, filling density is 285/10 centimetres, reaches desired unidirectional elastic elongation and dimensionally stable for making grey cloth, again through the arrangement of 120～140 ℃ HEAT SETTING.Fig. 1-1,1-2 are respectively the abrasion condition of common cog belt and cog belt of the present invention.
