Abstract
The invention relates to a main shaft decelerating device for a machine tool, belongs to the field of machine tools. The device is provided with a box body and is characterized in that: a fixed gear ring is fixed with a box body; a sliding gear is engaged with a big gear ring and is simultaneously engaged with the fixed gear ring; a shifting fork is arranged on the sliding gear; a planet carrier is fixed with an output shaft in the box body; a planet gear is fixed to planet carrier and is simultaneously engaged with a sun gear and the big gear; and the motor shaft is engaged with the sun gear. The main shaft decelerating device of the machine tool ensures an original connection mode and simultaneously realizes a function of a reduction gearbox by using a planet gear mechanism of a speed reducer, thereby saving space and reducing cost.
Description
Technical field
The present invention relates to machine tool field, especially a kind of machine tool chief axis deceleration device.
Background technology
As everyone knows: existing machine tool main shaft deceleration device adopts the external gear pump speed change, and cabinet space is big, cost is high.
Summary of the invention
Purpose of the present invention just is to overcome the deficiencies in the prior art, and a kind of machine tool chief axis deceleration device is provided, and when guaranteeing original connected mode, uses the decelerator planetary gears and realizes the reduction box function, thereby save the space, reduce cost.
The present invention adopts following technical solution: a kind of machine tool chief axis deceleration device, be provided with casing, it is characterized in that fixed gear ring and casing fix, shifting slide gear and bull gear engagement, shifting slide gear and fixed gear ring engagement simultaneously is equipped with shift fork on the shifting slide gear, output shaft in planet carrier and the casing is fixed, planetary gear is fixed on the planet carrier, and planetary gear and sun gear, bull gear mesh simultaneously simultaneously, motor shaft and sun gear engagement.
The invention has the beneficial effects as follows, when guaranteeing original connected mode, use with the decelerator planetary gears and realize the reduction box function, thereby save the space, reduce cost.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 structural representation of the present invention.
1. casings among the figure, 2. output shaft, 3. sun gear, 4. planetary gear, 5. bull gear, 6. fixed gear ring, 7. shifting slide gear, 8. motor shaft, 9. shift fork, 10. planet carrier, 11. position B.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, to help understanding content of the present invention.
As shown in Figure 1, shifting slide gear 7 of the present invention and bull gear 5 engagements, shifting slide gear 7 meshes with fixed gear ring 6 simultaneously, and shift fork 9 is installed on the shifting slide gear 7, and fixed gear ring 6 is fixing with casing 1.Motor shaft 8 and sun gear 3 engagements, planetary gear 4 is fixed on the planet carrier 10, and planetary gear 4 meshes simultaneously with sun gear 3, bull gear 5 simultaneously, and planet carrier 10 is fixing with output shaft 2.When motor shaft 8 rotations, drive sun gear 3 rotations, sun gear 3 drives output shaft with planetary gear 4 engagements, planetary gear 4 around sun gear 3 rotations, because sun gear 3 is different with the rotating speed of planetary gear 4, thereby realizes slowing down between motor shaft 8 and the output shaft 2; When shift fork 9 drive shifting slide gears 7 move to position B11, shifting slide gear 7 breaks away from fixed gear ring 6, shifting slide gear 7 meshes with motor shaft 8 simultaneously, when motor shaft 8 rotations, driving shifting slide gear 7 rotates simultaneously with sun gear 3, shifting slide gear 7 drives bull gear 5 rotations, thereby realizes motor shaft 8 and output shaft 2 constant speed transmissions before.
