Abstract
The utility model discloses an electronic shaft transmission device which comprises a main shaft, a servomotor, a speed reducer, a coupling, a transmission structure and an air cylinder, wherein the main shaft penetrates through a machine frame to be connected with the servomotor and the speed reducer by the coupling; the coupling drives the transmission structure consisting of a belt and a transmission wheel to rotate; a velometer is arranged on the coupling, and the servomotor is provided with a velocity measuring device; and the air cylinder at the bottom of the machine frame is connected with the main shaft. The servomotor operates to drive the main shaft to carry out rotary transmission, the main shaft is pushed by a piston of the air cylinder at the bottom to carry out transverse transmission, the loss generated by gear transmission is prevented from affecting the printing accuracy by the transmission structure consisting of the belt and the transmission wheel, meanwhile the noise is low, feedback is formed by the velometer arranged on the coupling and the velocity measuring device arranged on the servomotor, so that the speed regulation is enabled to be more accurate, a lubrication oil tank is arranged in the machine frame, and the transmission is enabled to be more stably, and the shaft jamming situation is prevented.
Description
Technical field
The utility model relates to a kind of electronical line shaft transmission device, belongs to the mechanical transmissioning technology field.
Background technology
In printing machine, what traditional electronical line shaft transmission was adopted is that servomotor passes through the rotation of shaft coupling driven gear, and the engagement between the gear drives the rotation of axle.But because the mismachining tolerance of gear can't be eliminated, long-term simultaneously the use caused wearing and tearing to gear unavoidably, therefore influences printing precision, makes the trapping printing difficulty, reduced the quality of printing.And along with the diversified requirement of printed matter, single rotation transmission can't have been satisfied, therefore needs precision higher, the diversified electronical line shaft transmission device of transmission.
The utility model content
The utility model relates to a kind of electronical line shaft transmission device, and is low to solve the conventional transmission device printing precision, the problem that transmission direction is single.
For realizing this purpose, the method that the utility model adopted is: a kind of electronical line shaft transmission device comprises main shaft, servo motor, shaft coupling, decelerator, drive mechanism and cylinder; It is characterized in that said main shaft passes the connecting hole on the frame, adopt shaft coupling to be connected with servo motor; The drive mechanism that shaft coupling drives on the main shaft rotates; Be provided with decelerator between shaft coupling and the servo motor, the frame bottom is provided with cylinder, and cylinder piston connects main shaft makes its transverse movement.
Said servo motor carries speed measuring device.Said shaft coupling has speed measuring device, and the speed measuring device that carries with said servo motor forms feedback.
Said drive mechanism comprises two drives and belt, and two drives are connected on support and the main shaft, between rely on belt to connect transmission.
Said frame and main shaft junction are provided with grease-box, on four jiaos at frame one end fixing hole are arranged, and both sides respectively are provided with a peep hole, and framework soleplate is provided with the slip holddown groove.
Its beneficial effect is: the servo motor running drives the main axis rotation transmission, and the bottomed cylinder piston promotes the horizontal transmission of main shaft, and the loss that has produced when the drive mechanism of belt and transmission wheel type has avoided gear-driven causes the influence to printing precision; And noise is low; The speed measuring device that velometer on the shaft coupling and servo motor carry forms feedback, makes speed regulation more accurate, and grease-box is arranged in the frame; Make transmission more steady, prevent that axle is stuck.
