| titleOfInvention | Manufacturing method of rubber coating insertion piece for head pulley of elevator |
| abstract | The invention discloses a method for manufacturing rubber coating inserting pieces of a head pulley of a hoister, which enables the rubber coating inserting pieces and double-side pressing strips to be uniformly distributed on the head pulley so as to meet head pulley structures with different diameters; calculating the approximate number m of the rubber-coating inserting pieces and the double-side pressing strips; calculating the residual arc length k of the outer circle surface of the head pulley of the elevator, which is not coated by the rubber-coated inserting sheet and the double-side pressing strip, uniformly distributing the residual arc length k in adjustable gaps n between the side edge of the fixed section of the double-side pressing strip and the side edge of the installation iron plate, and calculating the residual arc length h = k/m occupied by every two adjustable gaps n; taking the expansion widths L3 of the fixed sections of the double-side pressing strips with different specifications in the circumferential direction, respectively calculating the residual arc length h from small to large according to L3, and comparing the residual arc length h with 2n to obtain the double-side pressing strips with corresponding specifications; the invention avoids the repeated disassembly and assembly of the bilateral pressing strip and the cutting of the rubber-coated inserting piece, and can improve the balance performance of the head pulley of the elevator. |
