Abstract
The utility model discloses a transmission box of a vertical lathe. The transmission box comprises a box body, wherein an input shaft, a transmission shaft and an output shaft are arranged in the box body, and a direct-current speed reducing motor is arranged outside the box body and connected with the input shaft. A small input gear and a large input gear are arranged on the input shaft, and a sliding gear and a bevel gear are arranged on the transmission shaft. A speed reducing oil cylinder is connected onto the sliding gear which is pushed by the speed reducing oil cylinder to be meshed with the small input gear and the large input gear respectively. An output gear and a bevel gear are arranged on the output shaft, and the bevel gear on the output shaft and the bevel gear on the transmission shaft are meshed to form a bevel gear pair used for transmitting movement between the transmission shaft and the output shaft. The transmission box of the vertical lathe is simple in structure, small in power loss and high in transmission efficiency.
Description
Technical field
The utility model relates to a kind of lathe transmission mechanism, more particularly, relates in particular to a kind of vertical lathe transmission case.
Background technology
When big-and-middle-sized vertical lathe carries out machining to large-scale workpiece, need often to change the velocity of rotation of workpiece, specifically realize by the rotating speed that changes vertical lathe workstation.The main transformer speed system (transmission mechanism) of existing vertical lathe adopts the multi-stage gear speed change usually, 16 grades of gear graduations for example, and its course of work is speed change oil cylinder pushing shifting slide gear, changes the tooth ratio of inner gear of the gear box, to realize gear.Since be to adopt the multi-stage gear speed change, complex structure, and manufacturing cost is high, also can cause transmission mechanism power loss in the course of the work, causes transmission efficiency low.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of vertical lathe transmission case is provided, and optimizes product structure, and improves transmission efficiency, saves cost.
For achieving the above object, vertical lathe transmission case provided by the utility model, comprise casing, power shaft, power transmission shaft and output shaft are housed in the casing, power shaft laterally places the lower left of casing, and power transmission shaft laterally places the upper left side of casing, and is parallel with power shaft, output shaft vertically places the right side of casing, intersects with power transmission shaft; Casing is provided with dc speed-regulating motor outward, and this dc speed-regulating motor connects with power shaft, and input pinion and input gear wheel are installed on the power shaft; Shifting slide gear and bevel gear are installed on the power transmission shaft, and the shifting slide gear first line of a couplet is connected to the speed change oil cylinder, is meshed with input pinion and input gear wheel respectively by speed change oil cylinder pushing shifting slide gear; Output gear and bevel gear are installed on the output shaft, and the bevel gear on the output shaft and the engagement of the bevel gear on the power transmission shaft form bevel gear pair.
The utility model is simple in structure, utilizes the speed change characteristic of dc speed-regulating motor, cooperates the use of pulley gear, the large and small gear of input and bevel gear pair, can obtain high and low two grades of speed, thereby realizes that slewing range is large, the function of low-speed big.And the utility model all adopts reduction of speed than transmission, use close steps at a high speed, the low speed big speed ratio, so power loss is little, and the transmission efficiency height.

The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Consult illustrated in figures 1 and 2, the utility model vertical lathe transmission case, this transmission case is installed on the lathe bed of vertical lathe, comprise casing 1, power shaft 11, power transmission shaft 12 and output shaft 13 are housed in the casing 1, power shaft 11 laterally places the lower left of casing 1, power transmission shaft 12 laterally places the upper left side of casing 1, parallel with power shaft 11, output shaft 13 vertically places the right side of casing 1, intersects with power transmission shaft 12.
Be provided with dc speed-regulating motor 2 outside the casing 1, this dc speed-regulating motor 2 connects with power shaft 11, and input pinion 3 and input gear wheel 4 are installed on the power shaft 11, is interference fit between input gear wheel 4 and the power shaft 11.
Shifting slide gear 5 and bevel gear are installed on the power transmission shaft 12, are matched in clearance between shifting slide gear 5 and the power transmission shaft 12; Shifting slide gear 5 first line of a couplet are connected to speed change oil cylinder 6, promote shifting slide gear 5 by speed change oil cylinder 6 and mesh with input pinion 3 and input gear wheel 4 respectively.
Output gear 7 and bevel gear are installed on the output shaft 13, are interference fit between output gear 7 and the output shaft 13; The engagement of bevel gear on bevel gear on the output shaft 13 and the power transmission shaft 12 forms bevel gear pair 8, is used for transmitting the motion of 13 of power transmission shaft 12 and output shafts, is interference fit between two bevel gears of bevel gear pair 8 and power transmission shaft 12 and the output shaft 13.
Operation principle of the present utility model is: dc speed-regulating motor 2 startup work, band driven input shaft 11 rotates, promoting shifting slide gear 5 by speed change oil cylinder 6 meshes with input pinion 3 and input gear wheel 4 respectively, driving power transmission shaft 12 rotates, gearing by bevel gear pair 8 drives output shaft 13 and output gear 8 rotations again, transmission of power is on the workbench gear wheel (not shown) of lathe the most at last, make Lathe bench obtain high and low two grades of speed, cooperate again the speed governing of dc speed-regulating motor 2, reach workbench total travel stepless speed regulation from low speed to high speed.
