Technical Field

The invention relates to a dustproof and anti-throwing lubricating oil device of a machine, in particular to a dustproof protection device of a screw press.

Background

The lubrication and the dust prevention of the screw and nut motion pair determine the service life of the motion pair to a great extent. Sufficient lubrication is carried out, so that a layer of oil film with the thickness of about 1mm is adhered on the screw, the screw rotating at a high speed can throw the oil film away from the surface due to centrifugal force, oil is thrown for short, thrown oil drops pollute the surrounding working environment, and therefore the screw needs to be provided with an oil collecting cover. In order to keep the sport pair free of dust, the screw needs to be provided with a dust cover. The oil collecting cover and the dust cover are designed into an integrated protective cover. The existing protective cover adopts a canvas cylinder cover and a cylinder organ type cover, can well prevent dust and oil from being thrown by a screw rod, but the lubricating oil of the protective cover in the two modes can seep out of the surface of the protective cover, so that the protective cover is full of oil stains, the hammer head of the machine is full of oil stains, the service life is short, and the protective cover is inconvenient to install and disassemble and is not an ideal protective cover form.
