A bearing oil injector and method of using the same

Abstract

The invention belongs to the technical field of automobile service and maintenance. In order to solve the technical problems in the prior art, the invention provides a bearing oil injector. The bearing oil injector comprises a fixed plate, a first sealing shaft, a second sealing shaft and an oil injection chamber, wherein an oil injection nozzle is formed on one side of the fixed plate; the other side of the fixed plate, the first sealing shaft and the second sealing shaft are successively connected in sequence according to the size of the sectional area; an oil injection hole is formed on the first sealing shaft, the oil injection nozzle, the oil injection hole and the oil injection chamber are communicated successively, the oil injection chamber is of a structure which is opened at two ends, one end of the oil injection chamber is matched with the fixed plate, and the fixed plate is rotatably connected to one end of the oil injection chamber through the first sealing shaft. The invention further provides a using method. The using method comprises the steps of: A, putting a tapered roller bearing in the bearing oil injector to be compressed; B, injecting bearing oil after pressurizing the bearing oil and meanwhile rotating the oil injection chamber; and C, stopping injecting the bearing oil and taking out the tapered roller bearing. The bearing oil injector provided by the invention is fast in bearing oil injecting speed and good in effect.

Description

technical field [0001] The invention belongs to the technical field of automobile maintenance, and in particular relates to a bearing oil filler for tapered roller bearings and a use method thereof. Background technique [0002] When maintaining the wheel hub of light and heavy vehicles, it is often necessary to add bearing oil to the bearings in the wheel hub of the vehicle. The main function of the hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. At present, the existing filling of bearing oil often adopts manual oiling operation without using any other auxiliary equipment. And manual filling of bearing oil to the bearing in the vehicle wheel hub has following defectives: 1) manual filling speed is slow. It takes about 6-8 minutes to fill the bearing oil in a wheel hub; 2) The effect of manually filling the bearing oil is poor. Manual filling of bearing oi...

Problems solved by technology

At present, the existing filling of bearing oil often adopts manual oiling operation without using any other auxiliary equipment

And manual filling of bearing oil to the bearing in the vehicle wheel hub has the following defects: 1) manual filling speed is slow

It takes about 6-8 minutes to fill the bearing oil in a wheel hub; 2) The effect of manual filling of bearing oil is poor

Manual filling of bearing oil is difficult to ensure that the bearing oil fills the inside of the bearing, which may easily cause uneven or insufficient bearing oil inside the bearing, which will lead to damage and wear of the bearing in the vehicle hub and shorten the service life of the vehicle bearing; and the vehicle's When the bearing is cleaned, the original waste bearing oil and worn iron chips will remain inside. Due to the slow speed of manually filling the bearing oil into the bearing and the lack of internal filling, the original residual bearing oil cannot be cleaned out, which will cause iron Secondary wear and tear on bearings caused by shavings; and manual filling of bearing oil is very dependent on the operator's technical level. When filling bearing oil, bearing oil is prone to leakage, and the bearing oil that is spilled each time generally accounts for the total usage. More than 20% of the amount, resulting in waste of resources and greater harm to the environment
