Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0021] The accompanying drawing is a step diagram of a method for determining the filling amount of bearing vacuum grease, including the following steps:

[0022] 1) Measure and calculate the amount of grease filling for different schemes.

[0023] Use the "equal volume method" to accurately measure the remaining volume between the inner and outer rings of the bearing. Fill the space between the inner and outer rings of the bearing with water and measure the volume of the water with a precision measuring instrument to obtain the remaining volume between the inner and outer rings of the bearing. Then, according to the density of the selected vacuum grease, calculate the mass of grease that should be filled in different schemes, and use precision weighing equipment to weigh out the corresponding grease.

[0024] 2) Add grease according to diff...

Abstract

The invention relates to a vacuum lubricating grease adding process and discloses a method for confirming vacuum grease adding amount in a spatial mechanism bearing, and the method comprises the following steps: 1) measuring and calculating the grease adding amounts of different schemes; 2) adding the grease according to different adding amounts; 3) measuring the transmission efficiency of a whole machine; 4) testing according to different grease adding amounts; and 5) comparing and optimizing the adding process schemes. By adopting the verification method of comparing the adding schemes, the grease adding effects can be reflected visually, thus solving the blindness problem of adding vacuum grease of the prior art and achieving accurate, visual and effective beneficial effects.

Description

technical field [0001] The invention relates to a vacuum lubricating grease filling process, in particular to a method for determining the vacuum grease filling amount of a bearing of a space mechanism. Background technique [0002] The working environment of the space mechanism is special, and there are special requirements for the lubricating grease filled in the bearing. For example, it is necessary to use ultra-low volatility vacuum grease to ensure its normal operation. At the same time, it is required to strictly control the filling amount of vacuum grease to ensure that the mechanism has good lubricating performance. At present, the process of using vacuum grease in China is still immature. In the process of using vacuum grease on space mechanisms, there are no corresponding standards for filling volume, filling methods and operating specifications. There is a lack of verification methods for vacuum grease filling process. There is a certain degree of blindness in le...
