Food packaging machinery in what kind of reducer?
Food packaging machinery in what kind of reducer? Vacuum packing machine is composed of different components. Reducer is a kind of closed drive device used between prime mover and working machine. Its effect is to lower the higher speed of the prime mover to the lower speed required by the working machine, and increase the torque. The reducer is widely used because of its compact structure, reliable work, high efficiency, long service life, convenient use and maintenance, and convenient for batch production. Various electrical components are used in food machinery plants.
Food packaging machinery in what kind of reducer? At present, some types of reducer have standard series of products, such as involute cylindrical gear reducer standard series and cylindrical worm reducer standard series (Q/ zb125-73, etc. Therefore, we can choose the standard reducer according to the working requirements, or design and manufacture by ourselves. The working efficiency of bag packing machine is very high.
Food packaging machinery in what kind of reducer? There are many kinds of reducer, which can meet different requirements of various mechanical drives. According to the transmission type, can be divided into gear, worm and gear - worm reducer; According to the transmission level, can be divided into single stage, double stage and multistage reducer; According to the axis in the space position, can be divided into horizontal and vertical reducer; According to the layout of the transmission, it can be divided into expansion type, coaxial type and shunt type reducer.
Food packaging machinery in what kind of reducer? The ordinary reducer generally consists of a box, transmission parts, shafts and bearings, coupling parts and several accessories. Transmission parts, shafts and bearings, and coupling parts have been discussed in the preceding chapters. This section introduces the reducer casing and its structure. Reducer box is the base for installing gear and shafting parts, its structure has a great impact on the reducer's performance, manufacturing process, weight and cost.
Food packaging machinery in what kind of reducer? The material of box body is commonly used HT150 or HT200 cast, heavy duty reducer also useful cast steel zg200-400 or ZG230450 cast, in single production, can also be used A2A3 (1) steel plate. The box body should have enough rigidity to ensure the precision requirement of the axis positions of the transmission parts and avoid the influence of excessive deformation on the transmission quality. In order to increase the stiffness of the box, in addition to ensuring that the box and the bearing seat have enough wall thickness, should also be set in the box outside the bearing seat stiffening rib.
Food packaging machinery in what kind of reducer? In order to ensure the sealing after surface connection, the connection flange should have enough width, the roughness of the surface is R1<3. In order to prevent the lubricating oil from seeping out of the cutting surface, the oil that seeps into the cracks of the cutting surface will flow back to the oil pool through the oil groove. If splash lubrication is used for rolling bearings, the oil in the oil groove shall be introduced into the bearing chamber.
Food packaging machinery in what kind of reducer? In order to observe and check the meshing and lubrication of the gear, and inject lubricating oil, the peephole is opened on the box cover above the meshing of the gear shaft. An oil drain hole is provided at the bottom of the box seat for oil change and oil cleaning. Oil drain hole should be set at the lower part of the oil pool to drain dirty oil. Reducer commonly used casting box, the design should consider the casting process characteristics, so that the box shape is simple, uniform wall thickness, smooth transition, to facilitate molding and modeling.
