Abstract
The invention discloses an integrated planet gear deceleration mechanism of a copying grinder. The sun gear (3) fixed on the planet carrier (4) is equipped on the motor spindle (2) of the motor (1). The planet gear (8) on (4) meshes with gear ring (6) and gear (9). The (9) and the zonule wheel (11) are equipped on output shaft (10) and megazone wheel (14) is equipped on principle axis of the copying grinder (13). The strap (12) is mounted on the belt wheel groups including (11) and (14). The mechanism applies internal meshing and transfers load by several (8)s simultaneously to realize power split and steady transmission. The invention has advantages of compact structure, small volume and mass, large range of transmission ratio, high efficiency and low noise. It resolves the influence of grinding quality caused by large and unstable copying grinding load and reduces tremble during the transmission process.
Description
Technical field
The present invention relates to a kind of integrated planetary gear speed-reducing mechanism, especially relate to a kind of contour grinder integrated planetary gear speed-reducing mechanism.
Background technology
At present, contour grinder 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 contour grinder headstock, whether work reliable and stable, relation greatly not only requires spindle drive steady, and rotating speed is required also very strict.
Existing contour grinder 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, and backlass is big, and transmission is not steady; Because of profile copy grinding load is big and non-constant, and influence mill partly quality easily causes vibrations in the transmission process simultaneously, and noise is very big.
Summary of the invention
The technical problem to be solved in the present invention 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 invention 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 gear on the described planet carrier and gear ring and a gears engaged, a described gear and a small pulley are installed on the output shaft, one big belt wheel is installed on the contour grinder 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 the anglec of rotation, then should select servomotor for use.
Described planetary gear is 1-5, preferred 2-4, and more preferably 3.Planetary gear quantity increases, and can make transmission more steady.
Described planetary gear mechanism is done the gear drive of gyration with a gear and geometrical axis thereof around the geometrical axis of fixed-site, and engagement and with 1-5 planetary gear while transmitted load in adopting makes power dividing; During transmission because of its compact conformation, 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 contour grinder effective support is provided.
The present invention also has advantages such as volume and quality be little.
