Embodiment Construction
[0014] Below in conjunction with accompanying drawing and embodiment the present invention is further described:
[0015] figure 1 , figure 2 and image 3 The double gear anti-backlash feed box shown includes a box body 19, the input shaft I in the box body 19 is connected with the servo motor installed outside the box body 19, the driving gear 1 on the input shaft I is connected with the transmission The driven gear 2 on the shaft II meshes, and the driving gear 3 is installed on the transmission shaft II. The driving gear 3 meshes with the speed reduction gear 4 installed on the first-stage speed reduction shaft III. The driving gear 1 and the driven gear 2. The drive gear 3 and the speed reduction gear 4 transmit the feed motion to the first-level speed reduction shaft III; the first-level speed reduction shaft III is provided with two transmission gears 5A and 5B with the same parameters and opposite directions of rotation. The transmission gear 5A and the transmission...

The invention discloses a double-gear gapleass feeding box and relates to the technical field of mechanical device manufacture. The double-gear gapleass feeding box is provided with driving gears arranged inside a box body and installed on an input shaft, the driving gears are meshed with a gear installed on a transmission shaft, a drive gear installed on the transmission shaft is meshed with a gear installed on a primary speed-reducing shaft, and two transferring gears opposite in gear tooth rotating direction are arranged on the primary speed-reducing shaft. One transferring gear, a gear on a first secondary speed-reducing shaft, a gear on a first tertiary speed-reducing shaft and the gears on the output shaft form a first gear chain. The other transferring gear, a gear on a second secondary speed-reducing shaft, a gear on a second tertiary speed-reducing shaft and the gears on the output shaft form a second gear transmission chain. The gears on the output shaft are meshed with a work table gear ring. The problem of quality reduction of processed parts caused by complete machine tool accuracy influenced by transmission gear gaps can be solved.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing, in particular to a gear feed box used for transmission of large machine tools. Background technique [0002] Gear transmission is the main form of transmission for large machine tools, especially for large and heavy CNC machine tools with a stroke of more than 10 meters. The servo feed actuator uses rack and pinion transmission instead of ball screw transmission. Gear transmission has the advantages of simple structure, easy installation and adjustment, etc., but with gear transmission, there will always be backlash under normal working conditions, and vibration and noise will inevitably occur during intermittent cutting and forward and reverse motion. The gap between them directly affects the positioning accuracy and repeat positioning accuracy, affects the machining accuracy of the machine tool, and causes the quality of the processed parts to decline; therefore, when...
