Copper alloy copper alloy with high strength, good antifriction and wear resistance, but bronze than bearing alloy high hardness, poor running-in and embedded, suitable for overload and medium velocity.
This for the circulation fan is especially important for mill system, bearing quality bad rolling bearing parts in the form of point contact and line contact, long-term work under the high alternating contact stress.
% of the high-speed growth, and our country engineering plastics plastic bearing mainly rely on import, improper selection of bearing, if the early bearing service life will be shorter.
(
Size = narrower range of tolerance zone = more expensive price)
Tolerance zone is what mean?
Tolerance zone is set used in the process of production and processing and accurately measure the size of the difference of sequence.
Star yu river lake for you explain: harmonic reducer reducer can be divided into harmonic reducer and RV reducer, harmonic gear reducer is a kind of harmonic drive device, harmonic drive device including harmonic accelerator and harmonic reducer.
According to unilateral feed water pump impeller suction way classification: also called single suction pump, only on the impeller inlet;
Bilateral feed water pump: also called double suction pump, the impeller has a water inlet on both sides.
If the choice is greater than surplus to cooperate, will force bearing raceway geometry deformation shape, abnormal vibration during operation.
If choose the larger clearance fit, can make the bearing outer ring in the relative sliding bearing hole, rose sharply result in bearing damage.
The axial load or only from lending, embeddedness: materials for hard particles embedded, so as to reduce the sliding bearing surface scratch or abrasive wear performance, rolling, is only applicable to thin wall bearing, has the very high productivity, the purpose of the bearing shell: prevent bearing relative to the bearing axial and circumferential relative movement.
Applications: low speed, light load or intermittent work machine, according to the material classification list: strength enough material can be directly into bearing, such as brass, gray cast iron.
Dish with two bearings in the roll, the first to reduce the vibration of the mill, the real situation of material particle size and moisture control, and optimize the operation parameters of the mill.
Enterprise staff call the gas through a network of online technology, either does not support online repair, or turning, but the enterprise equipment not meet barring conditions now.
Fatliquoring cycle and fatliquoring setup problem Settings: a common interval hours, fatliquoring minutes every time, the analysis: the long cycle of fatliquoring, oil shortage, cause poor lubrication bearing, wear heavier.
