Problems solved by technology

Since the elevator transmission wheel is a steel casting, the mass is relatively large, and each elevator has five transmission wheels (three guides, one car roof, and one counterweight), so the starting load of the main engine is large, and the starting torque of the main engine is limited. The requirements are high, and the friction between the elevator drive wheel and the steel wire rope is steel and steel, the noise is loud, and the wire rope is easily damaged
According to the safety regulatio...

Embodiment Construction

[0021] The transmission wheel is Φ536 (wheel outer diameter)×Φ100 (wheel inner diameter)×90 / 120 (wheel edge thickness / hub thickness)-3 (number of rope grooves)×Φ13 (rope groove diameter)-19 (rope groove distance) Example: First, evenly brush the mold release liquid on the bottom mold and kraft of the transmission wheel mold of this specification, fix the bottom mold on the flower plate in the heating box, install the kraft, put a glass thermometer, and start heating; Brush the release liquid evenly on the upper mold, heat it in another heating box, put a glass thermometer on it, and when the temperature of the bottom mold thermometer is 160°C and the temperature of the upper mold thermometer is 185°C, install the upper mold of the mold on the card Come on husband, start pouring. Weigh 13.15 kg of monomer caprolactam masterbatch and put it into the melting tank, connect the condenser and receiving tank, plug in the glass thermometer to measure the temperature, heat the melt...

Abstract

The invention relates to a method for producing nylon 6 lifter transmission wheel. Wherein, it uses aminocaprolactam as mother material, uses accelerant at 1.2-16g of each kilogram mother material, solidifier at 3-4ml of each kilogram mother material, and toner at 0.45-0.55g at each kilogram mother material; first preparing active molecule, adding solidifier, and using eccentric irrigation technique to obtain the blank of nylon 6 lifter transmission wheel, processing the internal stress, mechanically processing to obtain the final wheel. The inventive product has low density, low weight, stable operation and high mechanical strength, etc. And its yellow is formed by adding HRPA paint, to reduce cost.

Description

technical field [0001] The invention relates to a method for manufacturing a nylon 6 elevator drive wheel, which belongs to the technical field of nylon products. Background technique [0002] At present, the lifting of the elevator is realized by utilizing the main engine to start to drive the rotation of the elevator drive wheel and the wire rope. Since the elevator transmission wheel is a steel casting, the mass is relatively large, and each elevator has five transmission wheels (three guides, one car roof, and one counterweight), so the starting load of the main engine is large, and the starting torque of the main engine is limited. The requirements are high, and there is steel-steel friction between the elevator drive wheel and the steel wire rope, the noise is large, and the wire rope is easily damaged. According to the safety regulations of the national elevator industry, the elevator driving wheel is a rotating part, and its appearance color must be warning yellow. ...
