Brick and tile building materials production line reducer, wear-resistant and dust-resistant purchasing guide

Brick and tile building materials production lines are usually accompanied by high dust, heavy loads and harsh working conditions of continuous operation. The quality of the reducer is directly related to the stability and efficiency of the entire production line. In view of the core requirements of wear resistance and dust resistance, the following is a systematic purchasing guide for you:

1. Core protection design: build a solid dust-proof and wear-resistant barrier

1. Box sealing and protection level: Brick and tile factory dust (such as gangue powder, clay powder) can easily invade the gear box and cause increased wear. A fully enclosed box structure must be selected, and the protection level should reach IP65 and above to effectively block the intrusion of fine dust and prevent lubricating oil leakage.

2. Wear-resistant technology of key components: Important components such as the main shaft of the brick machine and the shaft and gears in the reducer should be made of carbon steel or alloy steel and undergo quenching and tempering or quenching heat treatment processes. Hard tooth surface gears not only have extremely high wear resistance, but can also withstand large extrusion forces and impact loads, ensuring long-term stable operation of the equipment.

3. Scraper and transmission parts coating technology: For components that are directly involved in material extrusion (such as scrapers with floating shaft structures), it is recommended to use wear-resistant metal material coating technology, which can extend the service life by 4 to 7 times compared with ordinary materials and greatly reduce the frequency of replacement.

2. Model matching and performance parameters: adapted to heavy load conditions

1. Selection of reducer type: The mixing, conveying and extrusion links of the brick and tile production line are typical heavy-load and impact-resistant scenarios. It is recommended to use a hard tooth surface gear reducer or a cycloidal pinwheel reducer. This type of model has high rigidity and strong load-bearing capacity; while the worm gear reducer is not recommended for such high-load conditions due to its low efficiency and easy heat generation.

2. Calculation of torque and safety factor: Calculate the actual required torque according to the formula "Output torque = 9550 × motor power ÷ input speed". Since the brick machine has periodic impact loads during startup and extrusion, it is recommended that the safety factor of the rated torque be increased to more than 1.5 to 2 times to avoid tooth breakage due to overload.

3. Lubrication and cooling system: Harsh environments place extremely high demands on lubricating oil. Industrial gear oil with strong extreme pressure, anti-micropitting corrosion and excellent anti-emulsification properties (such as L-CKD series) is required. At the same time, considering the heat accumulation during continuous operation, a model with a heat sink or forced cooling system should be selected to prevent oil failure due to high temperature.

3. Pitfall avoidance and maintenance guarantee: reduce the whole life cycle cost

1. Reject low-quality and low-priced products: Some low-priced reducers on the market have problems with material shrinkage and insufficient gear hardness. In the high dust environment of brick and tile factories, they are prone to early wear and even the entire machine is scrapped. Be sure to choose a source manufacturer with technical support and quick after-sales response.

2. Installation accuracy control: The coaxiality error of the reducer and motor must be strictly controlled within ≤0.1mm. Installation misalignment will cause the bearing to bear additional radial force, causing rapid damage under heavy load, causing severe vibration and noise.
