Abstract

The invention discloses a rolling ball lead screw which comprises a screw, a nut and a circulator. The nut is fixed to the outer side of the screw, an oil way is formed in the nut, the circulator and a pre-pressing sheet are arranged at the contact position of the rear end of the nut and the screw, and steel balls are arranged on the screw. The rolling ball lead screw has the advantages that the oil way is formed in the nut, the lead screw can be lubricated, damage to the lead screw caused by friction can be reduced, and the lead screw is made of a high-manganese alloy and is resistant to friction, so that the service life of the lead screw is prolonged.

Description

A kind of ball screw
Technical field
The present invention relates to a kind of mechanical parts, relate in particular to a kind of ball screw.
Background technique
Ball screw is that rotation motion is converted into straight line motion, or straight line motion is converted into the desirable product of rotation motion, is widely used in various industry equipments and precision type instrument.But traditional ball screw, after service time is long, the wearing and tearing of screw mandrel are very large, and can generate heat, and can shorten the working life of screw mandrel, therefore, needs a kind of new technological scheme to address the above problem.
Summary of the invention
The invention provides a kind of ball screw of long service life.
The technical solution used in the present invention: a kind of ball screw comprises screw rod, nut and circulator, nut is fixed on screw rod outside, and nut is provided with oil duct, and nut back end and screw rod contacting point are provided with circulator and pre-compressing tablet, and screw rod is provided with steel ball.
Above-mentioned screw rod is high manganese.
Beneficial effect of the present invention: nut is provided with oil duct, can be lubricated screw mandrel, reduces the damage of friction to screw mandrel, and screw mandrel adopts high manganese to be material, wear-resisting, and increased the working life of screw mandrel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1, screw rod, 2, nut, 3, circulator, 4, pre-compressing tablet, 5, steel ball, 6, oil duct.
Embodiment
As shown in Figure 1, a kind of ball screw comprises screw rod 1, nut 2 and circulator 3, and nut 2 is fixed on screw rod 1 outside, and nut 2 is provided with oil duct 6, and nut 2 rear ends and screw rod 1 contacting point are provided with circulator 3 and pre-compressing tablet 4, and screw rod 1 is provided with steel ball 5.
Above-mentioned screw rod 1 is high manganese.
Beneficial effect of the present invention: nut 2 is provided with oil duct 6, can be lubricated screw mandrel, reduces the damage of friction to screw mandrel, and screw rod 1 adopts high manganese to be material, wear-resisting, and increased the working life of screw mandrel.
