Description

Large-scale gear hobbing machine worktable

Technical field

The utility model relates to a kind of panoramic table parts of large-scale gear hobbing machine, specifically is mainly used in the Gear Processing of major diameter, big modulus, has thoroughly abandoned the pattern of gear hobbing machine worktable first.Belong to field of machining.

Background technology

In prior art, the radial location mode of workbench is the static pressure taper seat, and complex structure requires the relative difficult that requires that backing-off cutting cooperates, to the also corresponding raising of the requirement of casting material, and maintenance difficult, it is uneconomic processing for gear wheel.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of easy to make, and cost is lower, and the gap is adjusted flexible, can satisfy the large-scale gear hobbing machine worktable of big modulus, gear wheel in large diameter requirement on machining accuracy fully.

The technical scheme that provides according to the utility model, large-scale gear hobbing machine worktable comprises rotary table, feature is: described rotary table, the interior circle of going up is connected with bolt respectively with the outer ring, big worm gear is connected with bolt with rotary table, radial roller, in being installed in, big roller goes up circle, between Nei Xiaquan and the outer ring, the outer ring is connected with table base by bolt, oil baffle is installed on the table base, worm screw is by first rolling bearing, second rolling bearing, the 3rd rolling bearing, the 4th rolling bearing is installed on the endless screw support, the 4th rolling bearing positions with gland, baffle plate is installed in and is used for first Mounting of Rolling Contact Bearing and location on the endless screw support, and connecting axle is connected by connecing axle with worm screw.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Easy to make, cost is lower, and the gap is adjusted flexible, can satisfy the requirement on machining accuracy of big modulus, gear wheel in large diameter fully, is applicable to the manufacturer of the in batches big modulus of professional production, gear wheel in large diameter.

The specific embodiment

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

As shown in Figure 1, comprise: comprise rotary table 1, table base 2, big worm gear 3, interiorly go up circle 4, radial roller 5, outer ring 6, big roller 7, interior circle 8 down, anti-oiled-plate method 9, connecting axle 10, connect axle 11, adjust compositions such as backing plate 12, endless screw support 13, first rolling bearing 14, baffle plate 15, second rolling bearing 16, the 3rd rolling bearing 17, worm screw 18, the 4th rolling bearing 19, gland 20.

The utility model rotary table 1, the interior circle 4 gone up are connected with bolt after the Vehicle Processing respectively with outer ring 6, big worm gear 3 is connected with bolt with rotary table, in being installed in, radial roller 5, big roller 7 go up between circle 4, interior circle 8 down and the outer ring 6, outer ring 6 is connected with table base 2 by bolt, and oil baffle 9 is installed on the table base 2 to prevent the seepage of lubricating oil.Worm screw 18 is installed on the endless screw support 13 by first rolling bearing 14, second rolling bearing 16, the 3rd rolling bearing 17, the 4th rolling bearing 19, the 4th rolling bearing 19 usefulness glands 20 position, baffle plate 15 is installed in installation and the location that is used for first rolling bearing 14 on the endless screw support 13, connecting axle 10 is connected by connecing axle 11 with worm screw 18, and adjustment backing plate 12 is used to adjust the gap between big worm gear 3 and the worm screw 18.

The radial location of the utility model panoramic table is that basic circle carries out finish turning processing with the contact-making surface of radial roller 5 fully, to guarantee the concentricity of part.Big worm gear 3 contacts for the static pressure face with outer ring 6, the control of radial clearance realizes that by ball 5 radially end play is adjusted by big roller 7, and roller can require match according to different gaps, method is flexible and cost is very low, and Vehicle Processing just can meet the demands after the roller path mid frequency induction hardening.Be connected with table base 2 usefulness bolts after the whole pivoting part installation, installation and maintenance are convenient, the gap of worm screw 18 and big worm gear 3 is realized by the thickness of adjusting backing plate 12, by connecing axle 11 and connecting axle 10 power is sent on the worm screw 18, realizes the rotation of rotary table 1.Worm and gear adopts oil immersed type lubricated, and rotary table 1 and table base 2 materials are cast iron, and big worm gear 3 adopts high-performance cast iron to prolong its service life.
