Embodiment 2

[0028] For a large-scale high-efficiency and durable energy-saving CNC screw press with a large pulley, the motor 1 and the pinion 31 are on the same side, which can effectively prevent the belt from being too long. The shape of this kind structure right vertical arm 5 is different from embodiment 1, is straight shape.

[0029] In order to avoid the wear and tear of the pinion due to long-term work and affect the service life of the pinion, the pinion shaft can be composed of a pinion 31 , a transmission shaft 32 and a flat key 33 . There can be 2 or 3 flat keys 33. After a part of the pinion 31 is worn, the position of the pinion 31 can be rotatably adjusted to effectively increase the life of the pinion 31.

[0030] In order to improve production efficiency, a moment of inertia adjustment ring 34 is added at the end of the large gear 17, and the moment of inertia adjustment ring 34 is fastened to the end of the large gear 17 to adjust the moment of inertia and achieve the pu...

Embodiment 3

[0032] In order to avoid wear and tear of the pinion due to long-term work and affect the service life of the pinion, the pinion shaft can be composed of a segmented pinion 35, a drive shaft 32 and a flat key 33. The split pinion 35 is connected with the power transmission shaft 32 through the flat key 33 in two stages. When using for a period of time, after a part of the segmented pinion 35 is worn out, the pinion 35 can be exchanged up and down to adjust the position of the segmented pinion 35, effectively increasing the life of the segmented pinion 35. All the other are with embodiment 1.

[0033] In order to improve production efficiency, a moment of inertia adjustment ring 34 is added in the bull gear 17, and the moment of inertia adjustment ring 34 is fastened in the bull gear 17. The moment of inertia adjusting ring 34 is an integral type or a combined type, and the combined type is composed of multiple pieces.

Abstract

The invention discloses an efficient durable energy-saving numerical control screw press, and belongs to the field of mechanical industrial equipment. An upper transmission system is connected with a motor (1), a screw press (19) and a brake (10) respectively; and a control system is connected with the control ends of the motor (1) and the brake (10). The upper transmission system comprises a belt drive, a gear drive, a half gear box with fixing function, a transmission box, a belt tension adjusting device and a belt flatness adjusting device. The half gear box comprises a front half box (12) and a rear half box (13) which are fixed connected with each other. the increased belt drive is connected with the gear drive so as to effectively protect a motor shaft. The increased half gear box ensures the precision of the gear drive, and the increased adjusting device tensions the belt and increases the drive torque. An increased positioning screw is convenient to adjust the flatness of the belt. An increased gearwheel and pinion adjusting device can ensure high efficiency and durability.

Description

technical field [0001] The invention provides an efficient and durable energy-saving numerical control screw press, which belongs to the field of mechanical industrial equipment. Background technique [0002] The Chinese patent number is ZL200520125153.5, and the invention patent titled CNC screw press discloses a screw press driven by a switched reluctance motor, and its large gear and the screw perform rotational motion.
