WS150-16-1 The box structure of the worm gear reducer has the following characteristics:
Overall structure : adopts a split structure, consisting of the upper box cover and the lower box seat, and the split surface is driven by the axis of the worm gear. This structure facilitates the installation and disassembly of shaft system components. During installation, components such as worm gear, worm, shaft and bearing can be assembled on the box seat, and then cover the box cover and fasten the box cover and the box seat together with bolts.
Material selection : Gray cast iron is usually used as the material for the box, such as HT250 or HT300. Gray cast iron has good casting properties and can be easily cast into various complex shapes, meeting the structural requirements of the box. At the same time, it also has excellent shock absorption performance, which can effectively absorb the vibration and noise generated by the reducer during operation, ensuring the smooth operation of the reducer. In addition, the cutting performance of gray cast iron is also good, which is convenient for processing various mounting holes and mating surfaces on the box.
Strength and stiffness design : In order to ensure that the box has sufficient strength and stiffness to withstand the force and external load of the internal transmission parts of the reducer, a series of measures have been taken in the design of the box. For example, reinforcement ribs are provided near the bearing hole to improve the support stiffness of the bearing seat and reduce deformation of the bearing seat when it is subjected to stress. At the same time, the wall thickness of the box is reasonably designed to ensure that the box will not crack or excessive deformation when it is under pressure.
Installation and connection structure : The box cover and the box seat are connected by bolts. In order to ensure the relative position accuracy of the box cover and the box seat, two positioning pins are also provided between the two. The arrangement of bolts needs to take into account the movement space required when using wrenches, and the bolts around the bearings will usually have a slightly larger diameter to be as close as possible to the bearings and improve the reliability of the connection. There is a anchor bolt hole at the bottom of the box to fix the reducer to the foundation or frame to ensure that the reducer will not be displaced during operation.
Accessories : An observation window or oil mark is provided on the box to check the oil level of the lubricant in the box so that the lubricant oil can be replenished or replaced in time. A respirator or breathable plug is also provided on the top of the box cover, which is designed to balance the air pressure inside and outside the box and prevent the increase in the air pressure due to the increase in the air pressure caused by the increase in the temperature inside the box, causing the lubricant to leak from the split surface or seal. There is an oil drain hole at the bottom of the box to facilitate the discharge of dirty oil and cleaning liquid when replacing lubricant.
