Description: The universal coupling (universal joint) is mainly used for large-scale corn screening and impurity removal equipment equipped with a belt drive structure. It connects the drive end with the vibration mechanism / conveying mechanism, and can compensate for axial, radial and angular deviations generated during installation, smoothly transmitting torque. Under the conditions of continuous feeding and screening of corn raw materials, it buffers operating impacts, preventing shaft system binding and bearing damage and ensuring stable operation of the feeding and screening system.
Principle The hinged structure composed of a universal joint fork a cross shaft and needle roller bearings allows for a certain angle between the two axes while reliable power transmission.
It can absorb positional shifts caused by equipment assembly errors and operational vibrations and remove stress concentrations caused by rigid connections.
Types
1. Cross Shaft Universal Coupling (Industry Mainstream) It consists of a universal joint fork a cross pin shaft.
Needle roller bearings and a sealing gland. High torque capacity, impact resistance and convenient assembly and disassembly.
Material: The main body is forged from 45# steel, and the bearings are dustproof and sealed to resist the intrusion of corn dust.
High-yield corn pretreatment linked screening equipment. Flexible Universal CouplingA rubber elastomer is installed in the middle.
Vibration damping and noise reduction, buffering the impact load of corn materials.
Drawbacks: The maximum torque it can withstand is lower than that of the cross shaft structure; Small and medium-sized feeding, conveying and screening linkage devices.
Performance Characteristics
1. It has angle compensation capability and tolerates welding and installation misalignment of the equipment frame.
2. The sealing structure design stop corn dust from entering the bearings, wear; 3. It resists impact loads and adapts to the load fluctuations caused by large-volume intermittent corn feeding.
4. Smooth transmission reduces abnormal noise and shield core components such as the motor, main shaft and bearings.
5. Maintenance is simple, and the service life can be extended by regularly adding lubricating grease.
Installation and Usage 1. Using them in pairs a better effect and reduces output speed fluctuations; 2. The angle between the two shafts should be controlled within the allowable range.
An excessively large deflection angle will aggravate wear and increase vibration; 3. Regularly check the fastening bolts to stop loosening caused by long-term vibration.
4. Dust covers are recommended to stop corn bran and dust from wearing the needle roller bearings. Scenarios Large-scale corn primary cleaning and screening units.
Supporting belt feed conveyors eccentric shaft driven grain cleaning screens and complete sets of raw material pretreatment equipment for corn starch and bio-fermentation production lines.
