How to improve the service life of the roller bearing The new type of deflection adjusting roller, including the conveyor belt, the conveyor belt is in contact with the roller, it consists of two parts: the deflection adjusting roller group and the deflection adjusting linkage. The deflection adjusting linkage part is: two parts on the conveyor belt The ends are respectively provided with vertical rollers, which are connected to the vertical rods through vertical rod connectors. The vertical rods are fixed with vertical rod connectors to connect to the horizontal rods. The horizontal rods are connected to the flat rods through precision adjusters. On the deflection roller group. This new type can solve the problems of poor deviation adjustment effect, complex structure and high failure rate. An edge roller used for self-aligning roller set with good performance, high impact resistance and low noise. This new type of rib roller for self-aligning roller set is realized through technical solutions. It includes a shaft. The outer peripheral surface of the shaft is adjacent to the inner peripheral surface of the molecular polyethylene roller skin. The upper and lower end surfaces of the roller skin are respectively provided with upper and lower circumferential surfaces. In the groove, the retaining ring for the lower shaft passes through the shaft and is arranged in the lower groove, the retaining ring for the upper shaft is located outside the shaft end and is arranged in the upper groove, and the outer side of the upper end surface of the shaft skin is provided with a blanking cover. The self-aligning roller group of the new type correcting device used for belt conveyors not only operates reliably, but also greatly reduces noise, and at the same time, there is almost no damage to the edges of the conveyor belt, which improves the service life of the belt. How to improve the service life of roller bearings.

1. Synchronous operation is basically realized between the supporting roller and the rubber belt, with little wear and tear between each other, extending the service life of the rubber belt and the driving rubber roller;

2. The roller steel tube is wrapped with tire rubber layer, and its anticorrosion and rust resistance are greatly improved. It bids farewell to the age of traditional rollers with large weight, low precision, high resistance, and no damage, and passed the lifting and transporting machinery The type test approval of the Quality Supervision and Inspection Center and the safety standard inspection of the Quality Supervision and Inspection Center of Coal Mining Machinery have achieved the mark.

3. The roller with the function of "device" and the unique longitudinal labyrinth seal structure is tested on the sealing performance simulation and strengthened test bench, dripping water does not enter, dustproof test, spotless, and prevents the sludge from affecting the roller Pollution.

The main features of DY mobile belt conveyor: use high-precision, hard-faced gears, with high load-bearing capacity (2-3 times higher than soft-faced wheels); long life (up to 10 years); compact structure, occupying The land area is small (can be reduced by more than 50%); heavy and light, small in size (can be reduced by 50%); especially the vertical transmission structure is suitable for use in underground mine transportation machinery. DY type mobile belt conveyor is a continuous conveying and loading equipment with high work efficiency, practicality and good maneuverability. Mainly used in places where loading and unloading locations change frequently, such as: ports, docks, stations, coal yards, warehouses, construction sites, sand and gravel yards, farms, etc., for short-distance transportation and loading and unloading of bulk materials or units weighing less than 100 kg Into an item. DY type mobile belt conveyor is divided into two categories: liftable and non-liftable. The conveyor belt is driven by electric rollers, and the lifting and running of the whole machine are non-motorized. DY type mobile belt conveyor is suitable for short-distance transportation and loading and unloading of bulk materials or pieces of goods. It adopts steel tube structure, which is light and beautiful, and has good mobility. The rotating device is an electric drum, and is equipped with two traveling wheels, pneumatic tires and steel wheels. The angle of inclination is adjustable over 10 meters.

Physical and chemical properties of polymer materials:

(1) Chemical: PH4-10;

(2) Shore hardness: 80A, lower than the hardness of the conveyor belt (90A), without wearing the conveyor belt;

(3) Tensile strength: 520kgf/cm2, good flexibility;

(4) Strong plasticity: different properties can be changed according to different requirements. Such as: flame retardant performance-can be changed by adding carbon elements;

(5) Possibility: Iron, as a common resource, gives us the illusion that it is a resource, but it has short-term impossibility and is an impossible source, and polymer materials can be synthesized by plants and possess feasibility.

(6) Polymer materials have great advantages in quality and low prices.

Traditional methods generally use machining after surfacing, and surfacing will cause the surface of the component to reach a high temperature, causing deformation or cracking of the component, and obtaining the size through machining will greatly extend the downtime. However, the use of Fuschlan polymer composite material for the site has no thermal influence, and the thickness is not limited. The product has the characteristics of the product and the retreat that the metal material does not have. It ensures 100% contact and coordination of the parts and reduces the impact and vibration of the equipment. , To avoid the possibility of wear. On-site, the method of avoiding machining saves a lot of downtime for the company and creates a huge production value.

The general bearing chamber wear can be completed in 3-6 hours, the operation is simple and easy to learn, no special equipment and special training are required, compared with laser welding, cold welding and other "" technology, it saves time and effort, and the cost is only 1/5 of the general cost. 1/10, the site is to reduce equipment maintenance time and transportation costs. The process is very simple, generally only four steps:

1. Surface treatment will need to remove oil and moisture from the bearing seat surface;

2. Reconcile materials;

3. Spread the material, evenly spread the material on the bearing seat, and fill it firmly;

4. Wait for the material to solidify, and the surface of the material can be appropriately heated to accelerate the material solidification.
