Embodiment Construction

[0011] Such as figure 1 As shown, there is a three-way oil channel 5 in the equipment 1, and the lubricating oil enters the equipment from the lubricating oil inlet pipeline 4, and then flows into the rolling bearings, bearing I2, and bearing II3 at both ends of the lubricating oil along the oil hole channel in the equipment 1. This design draws lessons from the idea and method of forced lubricating bearing bush or sliding bearing, and improves it, forming a new method of forcing rolling bearings at both ends of the equipment at the same time.

[0012] A lubricating bearing for oil drilling, comprising equipment 1, bearing I2 and bearing II3 installed on the equipment 1, oil inlet pipeline 4 and oil passage 5 inside the equipment are arranged on the equipment 1. The oil passage 5 can lead the oil passage 5 to the inside of the equipment 1 that needs to be filled with grease through an additional pipeline. Oil holes are arranged on the outer bearing caps of the bearing I2 and ...

Abstract

The invention discloses a lubricated bearing for petroleum drilling. The lubricated bearing comprises a device (1), a bearing I (2) and a bearing II (3) are installed on the device (1), an oil inlet pipe (4) is arranged on the device (1), and an oil channel (5) is arranged in the device (1). A lubrication mode comprising that the three-way oil channel is arranged in the device, lubricating oil enters into the device from the interior of the device, then is shunted to two sides and is forced to lubricate the bearing parts at two ends is adopted. The lubrication mode is suitable for bearings needing forced lubrication.

Description

technical field [0001] The invention belongs to the technical field of development and manufacture of transmission equipment such as drilling drawworks and parallel boxes in petroleum drilling and workover equipment. Background technique [0002] In the field, sliding bearings, bearing bushes or rolling bearings are installed inside some casings, and the positions where these bearings are installed are difficult to lubricate or it is difficult for people to reach places to add grease. For sliding bearings and bushings, the throttling effect of small holes (or gaps) is applied. Usually, sometimes a connected oil hole is processed inside the shaft. Lubricating oil enters from the bearing at one end of the shaft, and then flows into the other end through the oil hole channel. bearings. This method belongs to forced lubrication, and the effect is very good. But for rolling bearings, because the gap between the inner and outer rings of the bearing is too large, the lubricating ...
