Slow speed reducer motor is refers to the speed reducer and motor (motor) the integration of the body. This integration can also often called the body gear motor or gear motor. Usually carried out by professional reducer factory integrated complete sets of supply after assembled.
Geared motor is widely used in steel industry, machinery industry, etc. The gear motor strengths is to simplify programming, save space. Geared motor is generally through the motor. The internal combustion engine or other high speed work motivation 12v High Torque Motor through reducer input shaft less teeth on the gear engagement output shaft of big gear deceleration to achieve the intention. Gear motor is widely used, due to mechanical equipment indispensable power equipment, especially in the packaging machinery, printing machinery, corrugated machinery, color box machinery, transportation machinery, food machinery, three-dimensional parking equipment, active storage, warehouse, chemical, textile, dyeing and finishing equipment.
A structure plan features
(1) selection of isometric deflection, forward gear bearing ability, lunch, cuts, can speed up the process.
(2) to choose the foreign advanced cantilever type planetary frame structure, reduce the axial standards, make structure is tight, bento processing and equipment, reduce the cost. (3) the planet wheel using into the needle roller bearing, adapt to the characteristics of planetary transmission close reading, and increase the using life. Because of the small needle bearing relative standard, its price is lower than the other methods commonly used planet carrier domestic bearing.
(4) adopt the sun floating, to a larger degree of compensation due to the negative influence of processing error to equipment.
(5) choose hard tooth surface gear, six levels of accuracy, smooth operation, extended use of stature. Round the sun, the planets wheel used for carburizing steel, fine grinding, carburizing and quenching, tooth surface hardness: sun wheel Planetary Gear Motor can reach HRC58-6 l, planetary wheel HRC55-58. Choose nitrided steel inner ring gear, gear shaper after glow from the nitriding treatment, hardness can reach more than HV550 and nitride layer above 0.35 mm deep, tooth deformation after nitriding treatment, greatly advance the ring gear contact strength and abrasion resistance.
Planet carrier (6) each level and lower level sun wheel chooses 30 degrees involute spline coupling, with accurate positioning, equipment, maintenance bento, large carrying ability, planet carrier thickness is small, axial standard characteristic of close reading. With a conflict between two plates separated (bronze), under the condition of sufficient lubrication, bronze and hardening the sun round face a conflict vice, not only wear-resisting, and brief process, equipment for lunch. Planetary transmission between space per level 0.3 0.5 mm, the total area of 0.9-2 mm.
As reference when plan a lot about the planet carrier, pictures, materials, and differential comparison of their advantages and disadvantages, the plan will effectively combine different planets, through manufacturing, equipment, and running in user practice, proved that the reducer plan more beat, reasonable parameters, structure of close reading, manufacturing, equipment for lunch.
2. Carburized gear processing
(1) the carburizing process of gear machining process
Blank casting, rough rough machining to chemical composition inspection 24v Gear Motor and ultrasonic inspection, the workpiece pretreatment (normalizing or conditioning) - > ultrasonic testing - half finished - carburizing and quenching to finish machining, grinding to tooth surface magnetic powder flaw detection, tooth chamfer, dressing.
(2) the tooth surface deformation inspection after carburizing process
After carburizing treatment, easy deformation, after carburizing treatment processing, check all along with the deformation of cylindrical, should also check the tooth surface deformation, choose similar and across the great distance measurement of tooth thickness on both ends of the tooth width and midpoint, each measurement point fixed 3-5 measuring stick, will measure effect and the effect of the deformation of the cylindrical measuring contrast, summarized after the split deformation for grinding processing.
