Precision synchronous wheel

Timing pulley is generally made of steel, aluminum alloy, cast iron, brass and other materials, and its internal hole has round hole, D-shaped hole, tapered hole and other forms. The synchronous pulley drive is composed of a closed annular belt with equidistant teeth on the inner surface and corresponding pulley.

brief introduction

The surface treatment includes natural color oxidation, blackening, zinc plating, color zinc plating, high frequency quenching, etc. The accuracy level depends on customer requirements.

Feature editing

1. Accurate transmission, no sliding when working, with constant transmission ratio; 2. The transmission is stable, with buffering and damping capacity, and low noise; 3. High transmission efficiency, up to 0.98, with obvious energy-saving effect; 4. Convenient maintenance, no lubrication and low maintenance cost; 5. The speed ratio range is large, generally up to 10, and the linear speed can reach 50 m/s, with a large power transmission range, up to several watts to hundreds of kilowatts; 6. It can be used for long-distance transmission, and the center distance can reach more than 10m; 7. No pollution, can work normally in places where there is no pollution and the working environment is relatively bad.

Step Edit

1. Simplified design: according to the transmission power, input speed, transmission ratio and other conditions of gear transmission, determine the main parameters such as center distance and modulus. If the center distance and modulus are known, this step can be skipped.

2. Geometric design calculation: design and calculate the basic parameters of the gear, and calculate the geometric dimensions.

3. Strength check: after the basic parameters are determined, the accurate tooth surface contact strength and tooth root bending strength are checked.

advantage

The synchronous belt can be divided into neoprene plus fiber rope synchronous belt and polyurethane plus steel wire synchronous belt according to the material. According to the shape of the teeth, it can be divided into trapezoidal teeth and circular teeth. According to the arrangement of the teeth, it can also be divided into single-sided tooth synchronous belt and double-sided tooth synchronous belt. Synchronous belt drive has accurate transmission ratio, no slip, can obtain constant speed ratio, can be precise transmission, stable transmission, can absorb vibration, low noise, large transmission speed ratio range, generally up to 1:10, allowable linear speed up to 50 m/s, high transmission efficiency, generally up to 98% - 99%. The transmitted power ranges from a few watts to hundreds of kilowatts. Compact structure, suitable for multi-axis transmission, low tension, no lubrication, no pollution.

purpose

The synchronous pulley drive is composed of a closed annular belt with equidistant teeth on the inner surface and corresponding pulley. When moving, the belt teeth mesh with the grooves of the belt pulley to transmit motion and power. It is a kind of meshing transmission, which has various characteristics of gear transmission, chain transmission and belt transmission. It is widely used in automobile, textile, printing and packaging equipment, sewing equipment, office equipment, laser carving equipment, tobacco, financial machinery, stage lighting, communication and food machinery, medical machinery, steel machinery, petrochemical industry, instruments and meters, various precision machine tools and other fields.
