Maintenance method of trapezoidal screw

2023 01/20

The protection and maintenance method of the trapezoidal screw pair is the same as that of other rolling conflict transmission equipment. It should imitate the entry of hard dust or chips and dirt, so it is necessary to install imitative equipment. If the trapezoidal screw pair is exposed on the machine tool, a closed imitation shield should be used, such as a spiral spring steel belt casing, an elastic casing, and a folding casing. When equipment is used, one end of the imitation shield is connected to the side surface of the ball nut, and the other end is fixed on the support seat of the trapezoidal screw rod. If the trapezoidal screw rod pair is in a shaded position, a sealing ring can be selected for imitation, and the sealing ring is installed at both ends of the nut.
The touch-type elastic seal ring is made of oil-resistant rubber or nylon, and its inner hole is made into a shape that matches the screw thread raceway; the touch-type seal ring imitates the dust-the effect is good, but due to the touch pressure, the conflicting torque slightly increased. The non-touch seal ring is also called the labyrinth seal ring. It is made of hard plastic. Its inner hole has the opposite shape to the screw thread raceway, and has a slight gap. This can imitate the conflict torque, but imitate the dust- Poor fruit. At work, stop hitting the imitation protection equipment, and replace the imitation protection equipment in time if it is damaged.
