A power transmission chain (1) includes a plurality of link plates (2, 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H, 2J) aligned along the chain travel direction (X1) and a plurality of connection members (50, 3) connecting these link plates (2, 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H, 2J) to each other. When the link plates (2, 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H, 2J) are viewed along the chain width direction (W1), the link plates (2, 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H, 2J) each include discrimination portion (22, 22A, 22B, 22C, 22D, 22E, 22F, 22G, 22H, 22J, 22K) for discriminating the chain travel direction (X1).

In a minimum operation radius, long links are present one or more nodes at all times, and an upper limit to the number of long links is such that long links are present half or less of nodes that bite into a pulley.

When disposing pins of different shapes at random, pins of small involute base circle radius are made not to be arranged contiguously, pins of relatively small length are made not to be arranged contiguously, and pins of relatively outward offset are made not to be arranged contiguously.

A chain (1) includes plural links (2) and plural pairs of first and second pins (3 and 4) to couple the links each other. The first pin (3) comes into rolling and sliding contact with the second pin (4) at the contact portion (D). The first pin (3) includes a pair of end faces (17) opposing each other in the chain width direction (W), and a contact region (24) that comes into contact with the corresponding sheave surfaces of the pulley is formed in each end face (17). The contact region (24) includes the center point of contact (M). The first pin (3) includes a first type pin (3a) and a second type pin (3b). When the linear region of the chain (1) is viewed in the chain width direction (W), the relative position of the contact portion (D) and the center point of contact (M) is different between the first type pin (3a) and the second type pin (3b).

An endless loop-like chain 1p consists of a plurality of link plates, laminated, that are linked to be freely bendable by pin members. The endless loop-like chain 1p is looped over each of the upper rollers and a lower roller to make up a polygon. If the chain is rotated endlessly while a tension load is imposed on the chain by each of the rollers, a pretensioned chain is obtained.

The invention provides a power transmission chain in which abnormal noise can be reduced.In a link, a front through hole 7 and a rear through hole 8 aligned in a chain traveling direction X are provided. A pillar portion 9 is provided between the front through hole 7 and the rear through hole 8. Projecting portions 26, 29 are provided at a central portion in a height direction V of the pillar portion 9, and concave curve portions 27, 28, 30, 31 are provided at both end portions. A pair of flat portions (33,34 and 38,39) are provided on each projection portion 26,29 for restricting an overshoot of the chain. A not-shown pin that is loosely fitted to each of the front through hole 7 and the rear through hole 8 is brought into abutment with corresponding flat portions 27,28,30,31 to restrict an overshoot of the chain 1.

A torque transmission chain and torque transmission device of which the strength of links is increased by devising lock points that regulate the maximum relative rotation angle between the links are provided. Lock points that contact with pins and interpieces to regulate the maximum relative rotation angles are provided at four portions, that is, a front surface of a link front pillar portion, a rear surface of a link rear pillar portion and a front surface and rear surface of a link intermediate pillar portion. Each of allowable maximum relative rotation angles regulated by the lock points of a link outline portion is set so as to be smaller than each of allowable maximum relative rotation angles regulated by the lock points of the link intermediate pillar portion.
摘要:
Each of a plurality of displays transmits an operation state of the display to a management device. The management device stores the operation states corresponding to the plurality of displays in a memory. Based on the operation states corresponding to the plurality of displays and stored in the memory, the management device transmits a command for causing the display to perform the same operation as the other displays. Each of the plurality of displays changes the operation state of the display based on the command provided from the management device.

The first pin (3) comes into rolling and sliding contact with the second pin (4) at the contact portion (D). The first pin (3) includes a pair of end faces (17) opposing each other in the chain width direction (W), and a contact region (24) that comes into contact with the corresponding sheave surfaces of the pulley is formed in each end face (17). The contact region (24) includes the center point of contact (M). The first pin (3) includes a first type pin (3a) and a second type pin (3b). When the linear region of the chain (1) is viewed in the chain width direction (W), the relative position of the contact portion (D) and the center point of contact (M) is different between the first type pin (3a) and the second type pin (3b).
