KOYO bearing die casting method features and processes

The taper of the tapered roller is the same as the difference between the dimensions of the KOYO bearing inner roller. This is the basis for the satisfaction of the product KOYO bearing width. Therefore; as a new technology; random installation method Produced. In the final processing; there are many error factors affecting the roller scale; there are random errors and systematic errors. If the adjacent rollers are directly installed in a set of KOYO bearings, the sorting can be omitted. The process reaches the same installation quality. But no matter what kind of error; in a very short time; the scale of the adjacent rollers caused by them is not much different from each other.
Normative rules; detachable outer jackets need to be exchangeable; therefore, when selecting and installing; can not be selected for the outer ring. For other supporting parts; are arranged with the final inspection classification process; to select the corresponding parts for the matching.
Process characteristics of die casting method:
4. Easy to complete mechanization; improve working conditions.
3. The data utilization rate is high; the cost is significantly reduced.
2. After die-casting; metal crystals are condensed; finely arranged; good surface quality; solid and wear-resistant.
The professor should focus on: when die-casting aluminum alloy cages; demanding large-tonnage die-casting equipment; and the mold and production are more messy; the die-casting holes are easily injured during die-casting. The KOYO bearings receive shock, oscillation and speed changes. Under the conditions; further advance the quality of the die-cast cage.
1. The cage is directly die-casting; it can obtain outstanding shape and ruler accuracy; it can save the mechanical processing of the body cage rollover hole; high production efficiency.
The factors affecting the radial clearance or width of the rolling bearing; mainly the diameter error of the inner and outer ring raceways and the diameter error of the rolling body. Such production errors are not satisfactory for the rolling bearing replacement. Because the rolling bearing operation is important Sexuality; making the demand for clearance value or width public service very strict. At present; in the case of mass production; KOYO bearing parts processing economic accuracy scale is mostly 0. 04-0. 05mm. As long as the individual is separable KOYO bearing of the ferrule; only the exchange installation method is adopted. Therefore; regarding the installation of the rolling bearing; the usual exchange installation method cannot be selected; but the method of selecting and installing can be selected. In China; the radial clearance of the rolling bearing And the majority of the public service is now standardized. Take small and medium-sized deep groove ball bearings as an example; its radial clearance is only 0. 01-0. 02mm.
The inner and outer ring raceway diameters are grouped according to a certain scale difference within the scale of their service; then the inner ring and the outer ring of the corresponding scale are matched with a set of rolling bodies; to reach the technical specification or the current pattern rule. Value or KOYO bearing width public service. Such a process is called the selection and installation of rolling bearings; referred to as optional.

Wire Products generally includes Nails wire, Reinforcing wire, U type wire, Stainless steel wire, Black Annealed Wire, Galvanized Wire, PVC Coated Steel Wire And so on a series of products.
Nails wire also known as hard drawn wire, finds most in uses in nail making or weaving of wire mesh products.
Reinforcing wire usually uses for producing reinforcing wire mesh. It can be in coils or cut as 6m length.
U type wire material is low carton steel, Q235 or Q195.
Stainless steel wire uses for weaving of wire mesh, drawing of wire, in manufacturing of tie wire, nails and other metal products.
Black Iron Wire is made of high quality low carbon steel wire rod Q195 or Q235. The soft black iron wire comes into the form of coil wire, spool wire, U type wire or cut wire.
Galvanized Wire can be supplied in the form of coil wire, bobbins wire, spool wire, cut wire .
PVC Coated Steel Wire is the most popular plastic for coating wires as it is relatively low in cost, resilient, fire retardant and possesses good insulating properties. Its widely used in animal breeding, forestry protection, aquaculture, park and zoo Fence, the stadium, also used in other applications such as coat hangers and handles.
