Problems solved by technology

At present, the eccentric mechanism of the cone crusher in the prior art does not solve this problem well. For example, in the patent CN2714149Y, the inner sleeve of the eccentric sleeve has a gap with the outer sleeve due to the need for rotary motion. The sleeve will fall along the main shaft; in addition, the roller eccentric sleeve provided in the patent CN 101947476 A mainly relies on the rollers of the bearing to support the inner sleeve, which will cause premature wear of the roller bearing and affect the service life of the bearing

Embodiment 1

[0026] refer to Figure 1 to Figure 3 An eccentric sleeve mechanism with supporting bearings in the present invention comprises an outer sleeve 1, an eccentric inner sleeve 2, an upper roller bearing 3, a lower roller bearing 5 and a large bevel gear 8, and the outer sleeve 1 is fixedly mounted on a cone machine At the bottom of the frame 10, the inner wall of the outer sleeve 1 is provided with an upper roller bearing 3 and a lower roller bearing 5 sequentially from top to bottom, and the eccentric inner sleeve 2 passes through the upper roller bearing 3 and the lower roller bearing. 5 is movably installed in the outer sleeve 1, and the bottom of the eccentric inner sleeve 2 is equipped with a large bevel gear 8 for driving the eccentric sleeve mechanism, which is characterized in that it also includes an upper end cover 4, a plane bearing 6, a bottom end cover 7 and adjustment Gasket 9, the bottom end cover 7 is fixedly installed on the bottom of the outer sleeve 1, the uppe...

Embodiment 2

[0031] refer to Figure 4 , The difference from Embodiment 1 is that the plane bearing 6 is a plane ball bearing.

Embodiment 3

[0033] refer to Figure 5 , The difference from Embodiment 1 is that the plane bearing 6 is a plane sliding bearing.

[0034] Working process of the present invention:

[0035] The present invention is an eccentric sleeve mechanism with supporting bearings. When installing, the entire eccentric mechanism is assembled and installed on the bottom cone machine frame 10, and then the gear installation gap is adjusted by increasing or decreasing the adjustment gasket 9, and the movement of the eccentric mechanism is driven by The bevel gear 11 drives the driven large bevel gear 8, thereby driving the eccentric inner sleeve 2 to form a rotary motion. Due to the existence of the plane bearing 6, the sliding force generated by the eccentric inner sleeve 2 due to its own weight and the movement of the rotary motion process is absorbed by the plane bearing 6. Support, thereby ensuring the stability of the eccentric inner sleeve 2 during the rotary motion, thereby ensuring the stability...

Abstract

The invention provides an eccentric sleeve mechanism with a support bearing. The mechanism comprises an outer sleeve, an eccentric inner sleeve, an upper roller bearing, a lower roller bearing and a large bevel gear; the outer sleeve is fixedly mounted at the bottom of a cone machine frame; the eccentric inner sleeve is movably mounted in the outer sleeve through the upper roller bearing and the lower roller bearing; and the large bevel gear for driving the eccentric sleeve mechanism is mounted at the bottom of the eccentric inner sleeve. The mechanism is characterized by further comprising anupper end cover, a plane bearing, a bottom end cover and adjusting gaskets; the bottom end cover is fixedly mounted at the bottom of the outer sleeve; the plane bearing for supporting the eccentric inner sleeve is mounted on the upper end surface of the bottom end cover; and multiple adjusting gaskets for adjusting a gear matching gap are mounted in the connected place of the outer sleeve with the cone machine frame. The mechanism can guarantee the stability of the eccentric sleeve in the rotary moving process, so that the stability of the gear gap between the large bevel gear and the drivingbevel gear is improved, and the stop time in the production process and the maintenance cost are reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of components of a cone crusher, in particular to an eccentric sleeve mechanism with a supporting bearing. 【Background technique】 [0002] The eccentric sleeve mechanism is the key component of the cone crusher. The power transmitted by the gear drives the deflection movement of the cone of the crusher and the fixed cone liner to form a crushing cavity, thereby completing the crushing function. On the one hand, the eccentric sleeve mechanism provides deflection motion for the main shaft; on the other hand, due to its own gravity and friction during the rotation process, the inner sleeve of the eccentric sleeve has the problem of falling. At present, the eccentric mechanism of the cone crusher in the prior art does not solve this problem well. For example, in the patent CN2714149Y, the inner sleeve of the eccentric sleeve has a gap with the outer sleeve due to the need for rotary motion. The sleeve will fa...
