Detailed Description
The invention will be described in further detail with reference to the following figures and specific examples, without limiting the scope of the invention.
As shown in fig. 1, the method for dispersedly filling gear box grease according to this embodiment includes the following steps:
step S100: firstly, a rotary dispersion head extends into a gear box through a probing port of the gear box; the rotary dispersion head comprises a pressure maintaining chamber and a plurality of external bearing grooves which are uniformly distributed in a circumferential array, each external bearing groove is communicated with the pressure maintaining chamber through an external leakage channel, and the external bearing grooves are provided with shaping arc parts.
S200: then injecting the pressurized and heat-preserved lubricating grease into the pressure-preserving chamber through a pipeline, and storing the lubricating grease in a high-pressure state in the pressure-preserving chamber; preferably, the grease is pressurized to 2.5-3.5MPa and maintained at a temperature in the range of 22-26 ℃. Thus, the grease is in a high-pressure and flowable state, so that the grease can overflow from the pressure maintaining chamber into the external receiving groove.
S300: then, synchronously opening all the leakage channels, so that the lubricating grease in the pressure maintaining chamber enters each external bearing groove through the leakage channels under the action of pressure and is gathered; that is, the high-pressure grease in the pressure holding chamber overflows to the outside through the respective leakage passages, and the grease expands and accumulates in the outer receiving groove due to a change in the pressure difference.
S400: then synchronously closing all the leakage channels, cutting off the connection between partial lubricating grease gathered in the external bearing groove and the lubricating grease in the pressure maintaining chamber, and simultaneously enabling the outline of the partial lubricating grease to be granular by the shaping circular arc part; preferably, the volume of the external bearing groove is 0.4-0.7ml, the diameter of the leakage channel is 0.8-1.2mm, and the radius of the shaping circular arc part is 0.2 mm. The discharge amount of partial grease overflowed into the external bearing groove is controlled to be 0.8-1.3ml, so as to ensure that the grease completely covers the shaping arc part, and sufficient adhesive force is obtained in the processes of pressure reduction and volume expansion of the high-pressure grease.
S500: simultaneously driving each external bearing groove to rotate relative to the pressure maintaining chamber, and throwing out part of the lubricating grease in the external bearing grooves in a granular manner; preferably, the rotating speed of the outer bearing groove relative to the pressure-maintaining chamber is 320-. Thus, lubricating grease particles can uniformly fly out under the action of centrifugal force, and do not splash after contacting with parts in the gear box.
S600: repeating the steps S300 to S500, continuously dispersing lubricating grease particles, throwing the lubricating grease particles into the gear box, and fully lubricating parts in the gear box; so constantly through opening and closing of the passageway that leaks out the granule lubricating grease granule of shearing out, realize the abundant dispersion of lubricating grease, improve the utilization ratio of lubricating grease, avoid piling up the phenomenon and take place.
S700: and moving the rotary dispersion head to uniformly disperse the lubricating grease particles on the surface of the part in the gear box. The orientation of the rotary dispersion head is adjusted so that thrown lubricating grease particles can be uniformly dispersed in the gear box, lubricating grease filling is carried out on each surface of the parts in the gear box, and the lubricating effect of the parts in the gear box is improved.
And after the lubricating grease is filled, moving the rotary dispersion head out of the gear box.
This embodiment is through with pressurization, in the rotatory dispersion head of lubricating grease injection after the heat preservation, utilize rotatory dispersion head to cut out the lubricating grease granule in succession, and evenly throw away the lubricating grease granule of cutting apart to tooth incasement part surface, make lubricating grease fully dispersed, avoid the emergence of lubricating grease phenomenon of piling up, the lubricating grease utilization ratio improves greatly, and improve the lubrication effect of tooth incasement part, solve the limited problem that leads to lubricated badly in tooth case space, whole filling process easy operation, the filling is efficient.
