Abstract
An active-moving static pressure device of a gear shaper comprises a driving box, a crankshaft is mounted in the driving box via a positioning bearing and a supporting bearing, and a static pressure spindle sleeve is mounted outside the crankshaft. A static pressure oil slick is formed between the static pressure spindle sleeve and the crankshaft, so that the static pressure spindle sleeve and the crankshaft are not in contact during opposite movement, and are small in frictional resistance, sufficient in lubrication and less prone to heating, a rotating speed of active movement is greatly increased, and efficiency can be doubled.
Description
Technical field
The present invention relates to a kind of main motion static press device that the gear shaping machine main motion high speed transfer requires that is applicable to.
Background technology
The rotation of traditional gear shaping machine main motion is located with bearing, the bearing generation temperature rise of when High Rotation Speed, can generating heat, thus affect the speed of gear shaping machine main motion, grind the bad luck moving axis after speed is too high.
Summary of the invention
For the gear shaping machine main motion excessive velocities that overcomes big system is ground bad shortcoming easily, after the invention provides a kind of employing hydrostatic spindle kinematic axis being positioned, frictional resistance is little, and is fully lubricated, be difficult for heating, improved the gear shaping machine main motion static press device of main motion rotary speed.
The object of the present invention is achieved like this: a kind of gear shaping machine main motion static press device, comprise drive case, and crank axle is installed in the drive case by location bearing and spring bearing, and the hydrostatic spindle cover is housed outside crank axle.
Gear shaping machine main motion static press device provided by the invention forms the static pressure oil film between hydrostatic spindle cover and the crank axle, does not contact when mutually moving between the two, frictional resistance is little, and is fully lubricated, is difficult for heating, greatly improved the main motion rotary speed, efficient can double.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of gear shaping machine main motion static press device comprises drive case 1, and crank axle 3 is installed in the drive case 1 by location bearing 2 and spring bearing 4, and hydrostatic spindle cover 5 is housed outside crank axle 3.
Operation principle is as follows: drive case 1, location bearing 2, crank axle 3, spring bearing 4, hydrostatic spindle cover 5 are assembled; Integral body after the assembling is connected with lathe by drive case 1; Hydrostatic spindle cover 5 is carried out fuel feeding, and form oil film between the crank axle 3, utilize to form oil film between crank axle 3 and the hydrostatic spindle cover 5 and can make crank axle 3 frictional resistance when High Rotation Speed few, fully lubricated, be difficult for generating heat, provide crank axle 3 rotary speeies.
Claims (1)
