Abstract
The utility model relates to a sliding table gear transmission device for a servo numerical control machine tool, and belongs to the technical field of universal components of combined machine tools. The structure of connecting a servo motor and a lead screw in an existing servo numerical control combined machine tool through a coupling is changed, the servo motor is connected with the lead screw through a pair of gears with different rotation speeds, accordingly, output torque is improved, feeding force is increased, the tooth thicknesses of a driving gear and a driving gear pair are changed by adjusting the positions of the driving gear and the driving gear pair in a composite driving gear, the driving gear and the driving gear pair are jointly meshed with a driven gear to avoid forward and reverse clearance, and the driving gear, the driven gear and shafts of the driving gear and the driven gear are connected in a gapless manner by the aid of expansion sleeves. The gear transmission device is simple in structure and quite high in practicability.
Description
Technical field
The utility model relates to a kind of servo digital control machine tool sliding table gear drive, belongs to the modular unit for modular machine technical field.
Background technology
The servo digital control technology now often applies to the building-block machine field, servomotor and the leading screw of general servo digital control mechanical skid plateform are normally linked by coupling, the rotating ratio that is to say servomotor output speed and leading screw input speed is 1 ︰ 1, torque is 1 ︰ 1 than also, the centripetal force larger such as actual need of work, then need the larger servomotor of corresponding configuration, increased economic cost.
Summary of the invention
The purpose of this utility model provides a kind of servo digital control machine tool sliding table gear drive, solve in the existing servo digital control building-block machine because of servomotor and leading screw and link through coupling, exist rotating ratio and torque ratio to be 1 ︰ 1, if larger centripetal force is arranged, then need the deficiency of the larger servomotor of corresponding configuration, realize improving the output torque by the utility model, improve centripetal force, overcome simultaneously the gap between travelling gear.
The purpose of this utility model is achieved through the following technical solutions, a kind of servo digital control machine tool sliding table gear drive, comprise servomotor and leading screw, it is characterized in that, described servomotor is fixed on the transition casing of setting, fixedly place the compound driving gear in the transition casing on the axle of servomotor, compound driving gear is made of driving gear and driving tooth wheel set, the common engagement of driving gear and driving tooth wheel set is nested with the driven gear that is fixed on leading screw one end, and the driving gear secondary case is put on the ladder external diameter of driving gear; The inner surface of driving gear and driven gear all arranges expansion sleeve, and expansion sleeve is through the gland extruding with cylindrical body of the bolt that spins.
The end of the driving gear in the described compound driving gear arranges some mounting holes, and bolt is connected and fixed through driving gear mounting hole and driving tooth wheel set.
The rotating ratio of described compound driving gear and driven gear is 1 ︰ 2.
The structure that servomotor and leading screw link through coupling in the existing servo digital control building-block machine of the utility model change, be connected with leading screw by a pair of gear of servomotor through having different rotating speeds, thereby realized improving the output torque, improve the purpose of centripetal force, by regulating the position of driving gear and driving tooth wheel set in the compound driving gear, change the transverse tooth thickness of driving gear and driving tooth wheel set, jointly meshing driven gear is just realizing again, reverse gapless, by driving gear and driven gear and axle separately expansion sleeve is set and realizes seamless connectivity, the utility model is simple in structure, has very strong practicality.
