摘要： PROBLEM TO BE SOLVED: To obtain a transmission capability curve of a belt without necessitating a correction coefficient and the like by evaluating transmission capability of the belt from a relational formula between a Wd coefficient as push-press force of a pulley per belt unit length, and a ST coefficient as effective tension of the belt per unit winding length. SOLUTION: A relational formula between a Wd coefficient as push-press force of a pulley per belt unit length and a ST coefficient as effective tension of the belt per unit winding length, is found out in a high load transmitting belt. The ST coefficient is a value which effective tension of the belt is divided by a winding length of the pulley, and the WD coefficient is a value which the sum of the tension is divided by the effective pulley diameter of the pulley. Transmission capability of the belt is evaluated by the relational formula and transmission curves which are different from each other per a slip ratio in which the WD coefficient is set as a horizontal axis and the ST coefficient is set as a vertical axis, and a speed change range is predicted as a transmission condition of a transmission device. Accordingly, evaluation of belt transmission capability and the design of the transmission condition in the belt transmission device are facilitated.

摘要： PROBLEM TO BE SOLVED: To suppress timedepending changes in belt characteristics including belt sounds, heat generation and propelling force balance by providing projecting parts in left and right sides of each of blocks successively provided in a longitudinal direction such that the length of a pulley radial direction along a corresponding pulley groove surface is nearly constant and forming slide-contacting parts in the tips of the projecting parts. SOLUTION: A high load power transmission V belt b is composed of two endless tension belts 1 and 1 and a number of blocks 5, and a core wire 2 extending in a belt longitudinal direction is buried in each tension belt 1. In this case, projecting parts 15 are formed in left and right sides of each block 5 such that the lengths of pulley radial directions extending orthogonal to corresponding pulley groove surfaces 20a and along the same are formed to be nearly constant, and a slide-contact surface 11 slide-contacted with each pulley groove surface 20a is formed in the tip of each projecting part 15. The height of the projecting part 15 orthogonal to the pulley groove surface 20a is set such that the projecting part 15 is worn and eliminated by its slide-contacting with the pulley groove surface 20a immediately before a belt life reaches its end.

摘要： PURPOSE:To secure a meandering cancellation motion as well as preventing damage to a roller and a flat belt at the time when sliding is caused between the roller and the flat belt by protrusively providing a large number of needle bodies on the roller surface of roller members except the roller members for meandering adjustment. CONSTITUTION:When the edge part of a photosensitive belt 4 runs on a meandering detection member run on surface 11a due to displacement of the photosensitive belt 4, a detection member 11 is rotated against a support shaft 2a by a frictional force between the belt 4 and the detection member 11 and winds up a string member 13. A support shaft 3a shaft edge part on the edge part of a third roller member 3 where the detection member 11 is arranged is displaced by this winding-up, and the belt 4 is wound around in the opposite direction of A and travels, and then displacement of the belt 4 in the A direction is regulated. Simultaneously, a spring not shown in the drawing extends due to displacement of the shaft edge part, and the displacement amount of the roller member 3 is regulated by a balance between a wind-up force of the string member 13 and a spring force of the spring, and the edge part position of the belt 4 is maintained and meandering is cancelled. Additionally, damage to the belt 4 and rollers 1b, 2b is prevented by protrusively providing projections of aramid fiber of the elastic body rollers 1b, 2b.

摘要： PURPOSE:To provide a flexible bag-shaped body made of fiber members used as an air bag, and the like, capable of being manufactured easily and stored in a compact manner, and having a high reliability with a uniform property and a light weight by winding up in a bag form a tapelike member or a tape in which fiber filaments are arranged in a straight line or in a manner to maintain parallel conditions. CONSTITUTION:A tape-shaped open thread 1 is formed into a tape-shaped open thread 1 by a mechanical method wherein five pieces of 1500De/1000F yarn made of polyparaphenylene.3,4diphenylether telephthalamid are bundled to one piece and opened. The tread 1 is impregnated with EVA emulsion solution 3 by means of an elastomer solution impregnation device 2, and thereafter control of adhesive amount is carried out by a doctor knife 4 to provide an extremely thin tape 5. Then this tape 5 is passed between rollers 7-10 and wound around a metal disc-shaped mandrel 13 capable of being disassembled to which a separation agent is applied preliminarily through a reciprocating delivery member 11, thereby a required bag body 14 is provided.

摘要： PURPOSE:To manufacture a tough bag body fiber molding of integral structure which is easily wound and excellent in its storage property and highly reliable by winding a very thin tape etc. onto a mandrel while heating the tape, without molding the bag body from textile or knitting. CONSTITUTION:Tape-shaped open weaving yarn 1 is passed through a rubber solution impregnating device 2 and impregnated with a rubber solution 3 and then the amount of rubber attached to the yarn 1 is controlled using a doctor knife 4. A tape 5 thus obtained is passed between opposite rollers 7, 8 and passed around rollers 9, 10 and heated by a far infrared heater 11 and then wound onto a disc-shaped mandrel 14 via a delivery eye 14 reciprocating in the direction parallel to a rotary shaft 13; i.e. the tape-shaped open weaving yarn 1 is wound onto the mandrel 14 while being heated so as to obtain a bag body and thereby fiber is softened and its coefficient of friction is increased to prevent portions between the tapes or the tape and the mandrel from being slid against each other and freely control the wound form of the tape.

摘要： PURPOSE:To obtain a fire resistant impact absorbing bag of uniform quality and high reliability which can be easily manufactured by winding into a bag tape-shaped open weaving yarn coated with an elastomer composed mainly of a polymer containing halogen radicals in its molecular structure. CONSTITUTION:Open weaving yarn 1 in the form of a tape is passed through a rubber solution impregnating device 2 and impregnated with a rubber solution 3 and then the amount of rubber attached to the yarn 1 is controlled using a doctor knife 4.

摘要： PROBLEM TO BE SOLVED: To increase a transmitting load of a belt without increasing weight of blocks in a high load transmitting V belt of a block type in which tensile belts are fitted to fitting grooves on side surfaces of each block by reducing stress applied to a root of an upper side beam of the fitting groove, among reinforcing members embedded in each block. SOLUTION: A beam angle α is at least 90 degrees, which angle α is formed by vertical center line L of an upper side beam 13 and a pulley groove surface P1 of a block 7 on the pulley center side of a contact position of an upper side contact portion 11. Tensile stress due to shearing force in a longitudinal direction of the belt between the block 7 and a tensile belt 1 alone is applied to a root 13a of the upper side beam 13. Or, the smaller tensile stress is applied thereto, which is obtained by subtracting by compression stress due to downward bending moment applied to the upper side beam 13, caused by repulsion from the pulley groove surface P1.
