Machining process of wind power bearing sealing rubber strip

Abstract

The invention discloses a machining process of a wind power bearing sealing rubber strip, which is made of oil and weathering ageing resistant rubber. The machining process comprises the following steps of: filtering mixing rubber materials by using a filter screen and ensuring that the rubber materials are free of impurities; matching mouthpieces by using an extruder so as to pre-form the rubbermaterials and ensuring the sizes of the rubber materials so as to satisfy the weight requirement; preheating the pre-formed mixing rubber materials so as to increase the fluidity; dragging the pre-formed rubber materials to each die cavity by using a fixture and putting neatly; carrying out die assembly and vulcanization molding; and trimming the vulcanization molded products and removing the rough edges so as to obtain the wind power bearing sealing rubber strip which satisfies the assembling requirement. Through the invention, the quality of the sealing rubber strip can be improved and the quality stability can be ensured.

Description

technical field

[0001] The invention relates to a vulcanization molding processing technology, in particular to a processing technology of a wind power bearing sealing rubber strip. Background technique

[0002] At present, wind power bearing sealing strips are widely used in wind power main engine yaw bearings and pitch bearings, and play a sealing role in key parts. Whether it is yaw or pitch, the following requirements need to be met:

[0003] ① There is a certain pressure on the lubricating grease inside the bearing, which requires a certain strength and stiffness for the key lip part of the sealing strip.

[0004] ②The fan rotates with the wind direction at high altitude, and the blades will rotate continuously as long as the wind force permits, which requires the sealing strip to have considerable wear resistance.

[0005] ③ After the sealing strip is embedded in the sealing position of the bearing, it has been working in a compressed state, which requires that the d...

Examples

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] A processing technology for wind power bearing sealing strips, the material is oil-resistant and weather-resistant rubber, the hardness of the rubber is 70~75°Shore A, the process steps are as follows:

[0025] a. Filter the mixed rubber material with a filter to ensure that the rubber material is free of impurities;

[0026] b. Preform the rubber material with the mouth of the extruder to ensure the size of the rubber material so as to meet its weight requirements;

[0027] c. Preheat the preformed mixed rubber to increase its fluidity;

[0028] d. Draw the preformed rubber to each cavity with a jig and place it neatly;

[0029] e. Close the mold and start vulcanization molding;

[0030] f. Trim the vulcanized and formed product, remove the burr to make a wind power bearing sealing strip that meets the assembly requirements.
