Problems solved by technology

However, in the prior art, when the eccentric shaft of the crusher is driven to do work (crushing operation), it also produces an "exciting" effect of the eccentric shaft, that is, the crushing operation of the equipment is accompanied by vibration; the greater the crushing capacity, the greater the vibration

Embodiment 1

[0034] This embodiment discloses a gear-controlled vibration-free crusher assembly, such as Figure 1 to Figure 5 As shown, it includes a base 1, and the base 1 is provided with a vertical frame 11, and two groups of crushing mechanisms 2 are symmetrically fixed on opposite sides of the frame 11;

[0035] Each set of crushing mechanisms 2 includes a fixed jaw plate 21, an eccentric shaft 22 and a movable jaw assembly 3 fixedly connected to the frame 11; the eccentric shaft 22 drives the movable jaw assembly 3 to approach or move away from it Corresponding fixed jaw plate 21;

[0036] It also includes a drive motor 4, wherein a flywheel 5 is mounted on the eccentric shaft 22 of one group of crushing mechanisms 2, and the flywheel 5 is coaxially fixed to a driving gear 6; the other group of crushing mechanisms 2 is on the same side of the driving gear 6 A driven gear 7 is installed, and the driven gear 7 is coaxially fixedly connected with the eccentric shaft 22 of the correspo...

Embodiment 2

[0046] The difference between this embodiment and embodiment one is as Figure 5 and Figure 6 As shown, the bottom surface 315 is a curved surface, and the first side surface 313 and the second side surface 314 are arranged tangent to the upper and lower ends of the bottom surface 315 respectively. In this embodiment, the first side 313 and the second side 314 of the bracket groove 312 are set to be tangent to the bottom surface 315, which further reduces the angle change between the main stress-bearing surfaces in the bracket groove 312 and reduces the Stress concentration occurs on the movable jaw 31 at the toggle plate groove 312 due to the force at the toggle plate 32. This embodiment has good structural strength and a long service life.

[0047] In addition, in this embodiment, preferably, the width of the movable jaw 31 is L, and the thickness of the movable jaw 31 is H; the distance between the toggle groove 312 and the two ends of the movable jaw 31 in the width dire...

Abstract

The invention discloses a gear controlled vibration-free crusher assembly. The gear controlled vibration-free crusher assembly comprises a base; the base is provided with a vertical machine frame anda driving motor; the opposite two sides of the machine frame are symmetrically and fixedly connected to two groups of crushing mechanisms in a pressing manner; each group of the crushing mechanisms comprises a fixed jaw plate which is fixedly connected to the machine frame, an eccentric shaft and a movable jaw component; a flywheel is mounted on the eccentric shaft of one group of the crushing mechanisms and is coaxially and fixedly connected with a driving gear; a driven gear is mounted on the same side of the driving gear of the other group of the crushing mechanisms; the driven gear is coaxially and fixedly connected with the eccentric shaft of the corresponding crushing mechanism; the driving gear is in engaged connection with the driven gear; the movable jaw components of the two crushing mechanisms are synchronously close to or away from the corresponding jaw plates under the driving of the same driving motor; according to the gear controlled vibration-free crusher assembly, thevibration of the eccentric shafts can cancel out each other to reduce or eliminate vibration through opposite-impact arrangement.

Description

technical field [0001] The present invention relates to a jaw crusher, in particular to a crusher assembly that counteracts vibration through a counter design. Background technique [0002] Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. The crushing cavity is composed of two jaw plates, the movable jaw and the static jaw, which simulate the movement of the two jaws of animals to complete the material crushing operation. It is widely used in the crushing of various ores and bulk materials in mining smelting, building materials, roads, railways, water conservancy and chemical industries. The maximum compressive strength of the crushed material is 320Mpa. [0003] The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (fixed jaw), which is fixed vertically (or the upper end is slightly outward) on the front wall of the body, and the other is the movable jaw plate (moving jaw). Inclined, forming a crushing chamber with a la...
