Abstract
The utility model discloses an integrated planetary gear reducing mechanism for a profile grinder; a sun wheel (3) which is fixed on the planetary frame (4) is arranged on a motor main shaft (2) of the motor (1); planetary gears (8) which are arranged on the planetary frame (4) are meshed with a gear ring (6) and a gear (9); the gear (9) and a small belt wheel (11) are arranged on an output shaft (10); a large belt wheel (14) is arranged on a profile grinder main shaft (13) and a belt (12) is fit over a belt wheel group which consists of the large belt wheel (14) and the small belt wheel (11). The planetary gear reducing mechanism adopts inner gearing and a plurality of planetary gears for transferring loading at the same time; in this way, the diversion and the transmission of power are stable. The utility model is characterized by compact structure, small volume and mass, wide range of drive ratios, high efficiency, low noise and no reverse transmission clearance; moreover, the utility model properly solves the problem that the local grinding quality is affected because of the large and inconstant copy grinding load and at the same time reduces the shock produced in the transmission process.
Description
Technical field
The utility model relates to a kind of integrated planetary gear speed-reducing mechanism, especially relates to a kind of copying grinding machine integrated planetary gear speed-reducing mechanism.
Background technique
At present, copying grinding machine is primarily aimed at irregular axial workpiece and processes, and irregular axial workpiece often requires very high to contour accuracy and surface accuracy, promptly machining accuracy there is very high requirement, and will realizes high machining accuracy, whether steady with the motion of the copying grinding machine headstock, whether work reliable and stable, relation greatly not only requires spindle steady, and rotating speed is required also very strict.
Existing copying grinding machine reducing gear adopts belt multi-stage speed-reducing or worm and gear to slow down more, complex structure, and volume is big, and transmission efficiency is low; Because of copying grinding load is big and non-constant, and ring shadow mill partly quality, easily cause vibrations in the transmission process simultaneously, noise is very big.
The model utility content
The technical problems to be solved in the utility model is, the defective at prior art exists provides a kind of simple and compact for structure, and volume and quality are little, and gear range is big, stable drive, stable and reliable operation profiling grinding-machine integrated planetary gear speed-reducing mechanism.
Technical solution of the present utility model is, comprise a planetary gear mechanism, its sun gear that is fixed on the planet carrier is installed on the electric machine main shaft of motor, planetary pinion on the described planet carrier and gear ring and a gear engagement, a described gear and a small pulley are installed on the output shaft, one big belt wheel is installed on the copying grinding machine main shaft, and belt sleeve is contained on the belt wheel group that is made of big belt wheel and small pulley.
Described motor can be common electric machine or variable-frequency motor, when transmission needs certain required precision, when requiring certain precision as angle of swing, then should select actuating motor for use.
Described planetary pinion is 1-5, preferred 2-4, and more preferably 3.Planetary pinion quantity increases, and can make transmission more steady.
Described planetary gear mechanism is done the gear transmission of rotation motion with a gear and geometrical axis thereof around the geometrical axis of fixed-site, and engagement and with 1-5 planet wheel while transmitted load in adopting makes power dividing; During transmission because of its compact structure, stable drive, noise is low, shake little, thereby reduced the shake line that causes in the grinding process, improved transmission efficiency; Gear range is big, and this speed change for main shaft provides a bigger ranged space, can give full play to self-ability for copying grinding machine effective support is provided.
The utility model also has advantages such as volume and quality be little.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, the sun gear 3 that is fixed on the planet carrier 4 is installed on the electric machine main shaft 2 of motor 1, the planetary pinion 8 of planet carrier 4 and gear ring 6 and gear 9 engagements, gear 9 and small pulley 11 are installed on the output shaft 10, big belt wheel 14 is installed on the copying grinding machine main shaft 13, and belt 12 is sleeved on the belt wheel group of big belt wheel 14 and small pulley 11 formations; Sun gear 3, planet carrier 4, gear ring 7, planetary pinion 8, gear 9, output shaft 10 are installed in the shell 5.
During in course of working or at processing inhomogeneity part, the rotating speed of the headstock will change, according to actual conditions with need motor speed converse correspondent frequency, promptly obtain needed motor speed by the frequency of regulating frequency variator again, or machine spindle speed as required and motor speed calculate velocity ratio, reasonable computation sun gear, planetary gear ratio obtain the machine spindle speed that needs.During machine operation, rotate synchronously by electric machine main shaft 2 and sun gear 3, sun gear 3 drives motion by the planetary pinion on the planet carrier 48, planet tooth in the planet carrier 4 and gear ring 7 engagements, be fixed therein a planetary planet carrier 4 with the planet gear movement, the belt wheel driving mechanism by planet carrier 4 and the other end rotates machine tool chief axis.
