Abstract

The utility model discloses a planetary retarding mechanism for a B-axis milling head of a machining center. The planetary retarding mechanism comprises a fixed internal gear carrier, a planet carrier and gears connected with the planet carrier, wherein an input gear shaft is meshed with the gears which are meshed with the internal gear carrier, the planet carrier is fixed and coaxially rotates with an end cover, and an output gear is in keyed joint with the end cover. According to the structure, B-axis indexing and feeding movement can be met better while the mounting space can be reduced, the cost is controlled effectively, and the planetary retarding mechanism is suitable for feeding of the B-axis milling head of the machining center.

Description

Machining center B axle milling head planetary gear speed reducing mechanism
Technical field
The utility model relates to machine tool technology field.
Background technology
Milling head is as the vitals of five axle machining centers, and inside is provided with electric main shaft or mechanical main shaft and transmission mechanism, and for transferring power, calibration and feeding, wherein the version of calibration and feed mechanism has determined the machining accuracy of milling head.
Calibration and feed mechanism in milling head mainly contains the forms such as multi-stage gear speed change, reductor speed change and direct driving motor driving at present, and wherein multi-stage gear speed change requisite space is large, body of milling head processing difficulties, and assembly difficulty is large.Direct driving motor takes up space little, simple in structure, but cost is higher and need to carry out circulating cooling.
Utility model content
The technical problem that the utility model solves is to provide a kind of planetary reducer structure, both can dwindle take up space, reduced cost, again calibration and feeding accurately.
The technical solution adopted in the utility model is machining center B axle milling head planetary gear speed reducing mechanism, comprise input gear axle and output gear, comprise fixing internal tooth wheel carrier, planet carrier and the gear being connected with planet carrier, input gear axle is meshed with gear, gear is meshed with internal tooth wheel carrier, planet carrier is by screw fastening in internal end cover, and internal end cover and output gear are fixed on end cap by screw, and output gear is connected with end cap key.
Gear is installed on end cap by installation shaft and bearing.
The beneficial effects of the utility model are, a kind of planetary reducer structure of B axle milling head is provided, and make it when meeting preferably B axle calibration and feed motion, can reduce installing space again, effectively control cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the cutaway view that Fig. 1 is corresponding.
In figure, be labeled as: 3-screw, 4-internal tooth wheel carrier, 7-end cap, 8-output gear, 9-installation shaft, 10-gear, 12-planet carrier, 13-internal end cover, 15-key, 16-input gear axle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 Fig. 2, machining center B axle milling head planetary gear speed reducing mechanism described in the utility model, on internal tooth wheel carrier 4, be fixed with rotary seal ring, bearing, planet carrier 12 is anchored on internal end cover 13 by screw 3, internal end cover 13 and output gear 8 are fixed on end cap 7 by screw, gear 10 is arranged in installation shaft 9 by bearing, and output gear 8 is fixed on end cap 7 and coaxial rotation by key 15, screw and internal end cover 13.
During transmission, 16 rotations of input gear axle, gear 10 rotations that are meshed with it, because internal tooth wheel carrier 4 is fixing, therefore gear 10 drives planet carrier 12 together with end cap 7 and internal end cover 13 rotations, thereby drives output gear 8 rotations, and then controls the index feed of milling head.In less space, can realize larger gearratio like this, save space and cost-saving, and planetary gear also possesses the gap of disappearing function, raising machining accuracy.
