Abstract
The invention discloses a secondary planetary transmission, which belongs to machine tool accessories. The secondary planetary transmission comprises an input shaft, an output shaft, a shell and a fixed bracket. The secondary planetary transmission is characterized in that a sun gear and a planet gear are processed on the input shaft and are matched with an inner gear fixed on the shell, so as to form a planet speed reducing mechanism, a planet gear bracket with inner teeth is arranged between the planet gear and the shell, a clutch is fixedly connected to the inner end of the input shaft, the clutch and an inner gear of the planet gear bracket are respectively connected with a sliding clutch which sleeves the inner end of the output shaft in an alternate staggered mode, the sliding clutch is connected with a hydraulic cylinder arranged in the shell, and the input shaft, the output shaft, the planet gear and the whole transmission mechanism are installed in the shell by bearings. According to the secondary planetary transmission, the planet gear speed reducing mechanism is reasonably used, the planet bracket and the sliding clutch are designed, so as to form secondary transmission of the planet bracket and a main shaft, and secondary speed change is realized by hydraulic control over the sliding clutch.
Description
Technical field
The present invention relates to machine tool accessories, specifically a kind of secondary planet variator.
Background technology
The modern lathe being driven using frequency conversion motor, typically connects main shaft direct drive by frequency conversion motor although frequency conversion
Motor energy governing speed, but when cutting major diameter blank, low speed, roughing feed, high pulling torque requirement can be met, little cutting
When diameter the youthful and the elderly's part needs best bright finish, often not, vice versa for speed.
Content of the invention
High bright and clean in order to reach the major diameter of satisfaction processing simultaneously, roughing feed, low-speed big and minor diameter the youthful and the elderly's part, high speed
Two kinds of different requirements of degree, the present invention devises a kind of secondary planet variator.Technical scheme is: a kind of secondary planet speed change
Device, including input shaft, output shaft, housing, fixed support, is machined with sun gear and planetary gear on input shaft and is fixed on housing
On internal gear cooperation constitute planetary gear speed reducing mechanism, be provided with the planetary carrier with internal tooth between planetary gear and housing, defeated
Enter axle the inner and be fixedly connected with clutch, the internal tooth of clutch and planetary carrier respectively with the cunning being sleeved on output shaft the inner
Dynamic clutch replaces dislocation and connects and composes two grades of outputs；Slip-clutch is connected with the hydraulic jack being arranged in housing, by liquid
Compressing cylinder controls slip-clutch to slide two positions, realizes two stage speed change transmission in two stations；Input shaft, output shaft,
Planetary gear and whole drive mechanism are arranged in housing by bearing, and housing is arranged on lathe by fixed supporting frame.
The advantage of the present invention planet gear reducing mechanism that has been proper citation, devises planet stent and slip-clutch, structure
Become the secondary transmission of planet stent and main shaft, two stage speed change has been realized by hydraulic control slip-clutch.
Brief description
Fig. 1 is present configuration main view profile；
Fig. 2 is planetary gear position of the present invention cross-sectional view.
In figure: 1 is input shaft, 2 is planetary gear, and 3 is fixed annulus, and 4 is planet stent, and 5 is housing, and 6 is fixing
Bolster, 7 is slip-clutch, and 8 is hydraulic jack, 9 output shafts, and 10 is clutch.
Specific embodiment
As shown in Figure 1, 2, a kind of secondary planet of present invention variator, including input shaft 1, output shaft 9, housing 5, fixes and props up
Bolster 6, is machined with sun gear and planetary gear 2 on input shaft 1 and is fixed on the fixed annulus 3 cooperation composition planet on housing
Reducing gear, is provided with the planetary carrier 4 with internal tooth between planetary gear 2 and housing 5, is fixedly connected with input shaft 1 the inner
Clutch 10, the internal tooth of clutch 10 and planet stent 4 replaces mistake with the slip-clutch 7 being sleeved on output shaft the inner respectively
Position connects and composes two grades of outputs；Slip-clutch 7 is connected with the hydraulic jack 8 being arranged in housing, is controlled by hydraulic jack and slides
Dynamic clutch slides two positions, realizes two stage speed change transmission in two stations；Input shaft 1, output shaft 9, planetary gear 2 and whole
Individual drive mechanism is arranged in housing 5 by bearing, and housing 5 is arranged on lathe by fixed supporting frame 6.
