- this elevator has a car 1 (cage) for carrying people and luggage, and a weight 2 (a counter) is connected with a steel wire elevator overnight rope 3.
- the elevator rope 3 is wound around a sieve pulley 4 at the top of the hoistway to operate in a sleek manner.
- the pair of elevator driving belts 5 facing each other sandwiches the elevator rope 3 to apply a frictional force. That is, one of the driving belts 5 is wound between a driving pulley 7 and a driven pulley 8 which are coaxial with the output shaft of a hoist 6 (motor), and the other driving belt is driven. Belt 5 has two followers A pair of elevator driving belts 5 wraps between the pulleys 8 to press the elevator rope 3 to apply a frictional force.
- the elevator driving belt 5 exerts a frictional force on an elevator rope 3 connecting the elevator car 1 and the counterweight 2 to the elevator, and also suppresses a tally slip caused by a shear strain when the elevator is stopped. It is assumed that the rubber hardness is set so that
- the rubber hardness is set at about 50 to 90 degrees. That is, the surface layer 11 had a multilayer structure in which the hardness was set to 63 degrees with black mouth rubber and the intermediate layer 15 on the inner side thereof was set to 80 degrees in hardness with chloroprene rubber.
- the elevator driving belt 5 is pressed toward the elevator rope 3 by a pair of hydraulic devices 17, and a frictional force is applied between the elevator driving belt 5 and the elevator rope 3.
- the frictional force from the elevator driving belt 5 to the elevator rope 3 is adjusted by adjusting the pressing force by the pair of hydraulic devices 17.
- the frictional force applied to the elevator rope 3 is reduced due to the weight reduction due to the weight reduction of the car 1 and the counterweight 2, the frictional force applied from the elevator driving belt 5 to the elevator rope 3 is reduced.
- the driving force of the elevator can be ensured, the lobes 3 and guide rails 16 that support the elevator can be reduced in weight, and the overall cost of the elevator can be reduced.
- the rubber hardness is set so as to suppress creep slip due to shear strain when the elevator stops, the stability at the time of stopping can be ensured. Since the rubber hardness is set to about 50 to 90 degrees, oil oozes out from the inside and it is slippery. It is preferable to set), and it is possible to suppress the slippage due to the shear strain when the elevator is stopped (it is preferable to set the rubber hardness as high as possible), and to balance these contradictory important characteristics. There is an advantage that it can be done.
- the rubber material of the belt has a multilayer structure
- the elastic material forming the intermediate layer 15 is a rubber having a hardness equal to or higher than that of the rubber material of the surface layer 11, thereby further suppressing cleave distortion due to shear distortion.
- Grooves 12 corresponding to the shape and number (three) of the elevator lobes 3 are formed on the surface layer 11 of the rubber material that exerts a frictional force on the elevator lobes 3, so that they contact the elevator lobes 3.
- the grip surface can be increased by increasing the surface area.
- the elevator driving bell is fixed between the 106 pulley 4 and the other pulley 18 where the elevator rope 3 is fixed to the periphery and is non-rotatably fixed. And an unbalanced load W was applied to the belt 5 for driving the elevator by bolts B and loaded.
- the 5-axis belt load F was set to 30 O kgf, and up to kgf of the unbalance load W was measured. Specifically, the unbalance load W is increased, and the elevator rope 3 fixed to the pulley The load at which the belt 5 began to slip was recorded.
- the surface layer 11 was set to a hardness of 63 degrees with chloroprene rubber, and the inner layer 15 on the inner side was also set to a hardness of 63 degrees with chloroprene rubber. As a result, the load was 104 kgf.
- the surface layer 11 was set to a hardness of 63 degrees with chloroprene rubber, and the middle layer 15 on the inner side thereof was set to a hardness of 80 degrees with chloroprene rubber. As a result, the load was 11 O kgf.
- the hardness of the surface layer 11 was set to 80 degrees with chloroprene rubber, and the hardness of the intermediate layer 15 on the inner side was also set to 80 degrees with chloroprene rubber. As a result, load was 9 8 kgf c (Example 4)
