Abstract

The utility model discloses a centrifugal force oil supply lubrication structure for a planet wheel bearing of a planetary reduction gear. A ring gear (5) of the planetary reduction gear is installed in a shell (1). A sun wheel (3) and a planet carrier (4) are installed in the shell (1) through a bearing. A planet wheel (6) is installed in the planet carrier (4) through a planet bearing (7) and a pin (8). An annular oil slot (11) is arranged on the inner ring of the planet carrier (4). One end of the guide plate (2) installed in the shell (1) is led to the annular oil slot (11). A through oil guide hole (10) is arranged on the planet carrier (4) and the pin (8). The two ends of the oil guide hole (10) are respectively communicated with the annular oil slot (11) and the cavity of the planet bearing (7) to form an oil feeding channel. The utility model has the advantages that the lubricating oil is led to the cavity of the planet bearing by using the centrifugal force generated by high-speed rotation of the planet carrier, the bearing lubrication is realized, no special lubricating oil pump is required in the lubrication structure, the oil supply is continuous and uninterrupted and the lubrication effect is ideal.

Description

The lubricating structure of planetary reducer planet wheel bearing centrifugal force fuel feeding

Technical field

The utility model belongs to mechanical field, is specifically related to a kind of lubricating structure of planetary reducer planet wheel bearing centrifugal force fuel feeding.

Background technique

Planetary reducer has that compact structure, bearing capacity are big, stable drive, efficient height, easy to install, the life-span is long and noise is low characteristics.Extensively apply to industries such as building materials, metallurgy, mine, the energy.The lubricated of Domestic market planetary reducer mainly is bath-splash lubrication or external recycle oil pressure lubrication at present.Retarder is the high deceleration device particularly, and the bearing of supporting planet wheel is not only wanted autobiography, and will revolve round the sun along sun gear, the oil bath of this bearing is splashed or the recycle oil jet lubrication can not be continuous, lubrication effect is undesirable, and the very fast and superheating phenomenon of temperature rise appears in bearing easily, causes damage of bearings.

Summary of the invention

The purpose of this utility model is: the lubricating structure that designs a kind of planetary reducer planet wheel bearing centrifugal force fuel feeding, centrifugal force when utilizing the planet carrier high speed rotating, lubricant oil is guided to the planet wheel bearing inner chamber, realization is lubricated to bearing, this lubricating structure does not need the special lube pump, fuel feeding is uninterrupted continuously, the lubrication effect ideal.

Technical solution of the present utility model is: this retarder comprises housing, sun gear, planet carrier, ring gear, planet wheel, planet wheel bearing, bearing pin and end ring, ring gear is installed in the housing, sun gear and planet carrier through Bearing Installation in housing, planet carrier also can be unsteady fully, planet wheel is installed in the planet carrier by planet wheel bearing and bearing pin, planet wheel and planet wheel bearing are positioned on the bearing pin by end ring, it is characterized in that: the inner ring at planet carrier is established annular oil groove, establish the radial and axial oil guiding hole of mutual perforation on planet carrier and bearing pin, the two ends of oil guiding hole are communicated with annular oil groove respectively and the planet wheel bearing inner chamber forms feeding gallery.

In the lubricating structure of planetary reducer planet wheel bearing centrifugal force fuel feeding of the present utility model, an end that is installed in the guide plate in the housing is guided annular oil groove into.

During work, sun gear rotates, planet wheel rotation and along the sun gear revolution under sun gear and ring gear acting in conjunction, and planet wheel drives the planet carrier high speed rotating by bearing pin and planet wheel bearing; Lubricant oil flows into by guide plate in the annular oil groove of planet carrier, and lubricant oil is along with the planet carrier high speed rotating and produce centrifugal motion and flow into radial and axial oil guiding hole, and lubricant oil enters the planet wheel bearing inner chamber along oil guiding hole and realizes lubricated to planet wheel bearing.

The utlity model has following advantage: 1. the lubricating oil centrifugation motion produces charge oil pressure, and lubricant oil flows in oil guiding hole fast, does not need the special lube oil pump feed, and is simple in structure; 2. not being subjected to the revolution of planet wheel and bearing, the position is unfixed influences, and the planet wheel bearing fuel feeding is kept continuously uninterrupted; 3. lubricant oil flows does not have pipe joint along the journey asphalt channel and connects, in use can be not former thereby loosening, solid and reliable because of vibration etc.; 4. because the fitting surface that asphalt channel is flowed through is interference fit, can not occur as the common loosening and oil seepage phenomena of common lubricating pipe.
