Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Example: such as Figure 2~4 As shown, a gear transmission device of a wide double-point punching machine includes a transmission gear 2 fixed on the transmission shaft 1 and two main gears 3 and 3' driven by the transmission gear 2. The transmission gear 2 passes through The transmission shaft 1 is connected with the power unit 5, the main gear 3 and the main gear 3' are separated from each other and arranged on both sides of the transmission gear 2, the transmission gear 2 and the main gear 3 are indirectly meshed through the idler 4, the main gear 3' and the transmission gear 2 direct engagement. The center of circle of main gear 3, main gear 3 ', transmission gear 2 and idler gear 4 is all located on same horizontal line.

[0017] In the above embodiment, the transmission gear 2 can also be integrally arranged on the transmission ...

Abstract

The invention discloses a gear transmission device of a double-point punch, which comprises a transmission gear fixed on a transmission shaft and two main gears driven by the transmission gear. The transmission gear is connected with a power device through the transmission shaft. The gear transmission device is characterized in that the two main gears are mutually and separately arranged on two sides of the transmission gear, at least one of the two main gears is indirectly meshed with the transmission gear through an idler wheel mechanism. The gear transmission device has the advantages that: the outside diameter of the main gear can expand the space between fulcrums in the range of not interfering the inner width of a body, the compressive capacity of eccentric load in the left and right directions can be greatly improved by expanding the space between two fulcrums, and simultaneously the dynamic precision in multi-process punch processing aspects such as transfer processing and the like; because the transmission gear become small, the inertia of a punch transmission train becomes small, and then the running properties such as starting, stopping and the like are improved; and the space between the fulcrums can be freely selected by changing the tooth number of idler wheels in the idler wheel mechanism and the number of the idler wheels.

Description

technical field [0001] The invention relates to a transmission device of a punch press, in particular to a gear transmission device of a double-point punch press. Background technique [0002] The two-point punching machine mainly drives the crankshaft and connecting rod through a set of gear transmission to drive the movement of the slider, and punches through the reciprocating movement of the slider up and down. The gear transmission device of the existing common type double-point punch press is as follows: figure 1 As shown, it includes two left and right main gears that are directly meshed with each other and a transmission pinion. The transmission pinion is connected to the power device through a transmission shaft. The transmission pinion meshes with one of the main gears and drives the other main gear through the main gear. gear, this is the so-called "tandem transmission". [0003] But there are two problems in the gear transmission of this mode: [0004] One, the...
