Small Worm Gear MIM Parts

Product Introduction

Difference Between Worm Gear and Worm

To judge who is the worm gear and the worm, as long as it can be used as the active part, it is the worm, and the driven part is the worm gear, because the worm gear and worm transmission pair have self-locking characteristics. In the adjustable wrench, the part that rotates with the thumb to adjust the opening and closing of the wrench is the worm, because the part with the movable wrench opening cannot be used as the active part.

1. Difference

(1) The worm wheel is equivalent to the gear; the worm is equivalent to the rack.

(2) The worm is the active part; the worm gear is the driven part.

(3) Many worm gears have an interesting property that other gear sets do not have: the worm can easily turn the gear, but the gear cannot turn the worm. This is because the lugs on the screw are so shallow that when the gear tries to turn the screw, friction between the gear and the screw keeps the screw in place.

2. Judgment of direction of rotation

Determine the direction of rotation of the worm or worm wheel: erect the axis of the worm wheel or worm, the height on the right side of the helix is right-handed, and the height on the left side of the helix is left-handed.

Judgment of steering: Use the right-hand rule for right-handed rotation. The active worm is right-handed. Use the four fingers of your right hand to hold the worm along the direction of the worm.

If you want to judge the rotation direction of a gear at hand, you can put the gear flat in front of you and look at the direction of the teeth. If the left side is high and the right side is low, it means left rotation. On the contrary, it is right-handed.

Determination of the direction of rotation of the helical gear:

Left-right hand rule: left-handed use the left hand, right-handed use the right thumb and axial coincidence, four fingers point to the upward direction of the helical teeth, the left hand is left-handed, and the right hand is right-handed (always the back of the hand is facing you).

Worm gear industry market development

1. The prospect of demand for reducers in the lifting and transportation equipment industry

my country's lifting and transportation equipment manufacturing industry is facing good opportunities for development. The accelerated implementation of urbanization has led to a huge demand for machinery and equipment in the construction of urban infrastructure, which has created a good macro environment for the development of lifting and transportation equipment manufacturing enterprises.

Lifting and transportation equipment is the most widely used industry for reducers, and the development speed of this industry directly affects the speed of growth in market demand for reducers.

2. The demand prospect of the cement machinery industry for the reducer

Cement machinery is an important industry to revitalize the cement industry. With the state's policy support for infrastructure construction and the strengthening of the macro-control of the cement industry, the growth space for the cement machinery market demand will be broader, and the cement machinery industry will develop in a more reasonable direction. The reducer is the second largest type of general-purpose mechanical equipment used in cement machinery, and its market prosperity will inevitably continue to rise along with the strong demand of the cement machinery industry.

3. The prospect of demand for reducers in the metallurgical machinery industry

In recent years, under the guidance of the national macro-control, the iron and steel industry has strictly controlled the total production capacity, accelerated the elimination of backward production capacity, and strictly controlled new production capacity. After long-term extensive expansion, the iron and steel industry urgently needs to speed up structural adjustment and industrial upgrading. This adjustment has brought challenges to the metallurgical heavy machinery manufacturing industry, especially the high-tech high-end equipment manufacturing industry, and also brought market opportunities. .

4. The prospect of demand for reducers in the robot industry

The robotics industry is currently the most watched industry, and it goes without saying that there is room for development. The precision reducer is the most critical functional component in industrial robots and a crucial application link in the robot industry chain.

Mold and Gage

1. Mold service life: usually semi-permanent. (except lost foam)

2. Mold delivery time: 10-25 days, (according to product structure and product size).

3. Tooling and mold maintenance: Zhongwei is responsible for precision parts.

Quality Control

1. Quality control: The defective rate is less than 0.1%.

2. Samples and trial runs will be 100% inspected during production and before shipment, sample inspection for mass production according to ISDO standards or customer requirements.

3. Testing equipment: flaw detection, spectrum analyzer, golden image analyzer, three-coordinate measuring machine, hardness testing equipment, tensile testing machine.
