Abstract
The utility model discloses a reducer with a combined sealing structure capable of being arranged on three sides. An input shaft (3), a transition driven shaft (4), a transition driving shaft (5) and an output shaft (6) are installed inside a box body which consists of an upper box cover (1) and a lower box cover (2), and the input shaft (3), the transition driven shaft (4), the transition driving shaft (5) and the output shaft (6) are connected with each other through gears and accessories (7) to form the reducer. The reducer is characterized in that: a bearing (11) of the input shaft (3) and the output shaft (6) is provided with a bearing ring (12) a plurality of pressure releasing holes are uniformly distributed on the bearing ring (12), a plurality of oil discharging holes are uniformly distributed on a bearing seat (13) of the upper box cover (1) and the lower box cover (2), and each pressure releasing hole on the bearing ring (12) is communicated with each oil discharging hole on the bearing seat (13). The combined sealing structure with the pressure releasing holes is adopted, so the reducer can be arranged by the front surface and also can be arranged by two side surfaces, and the reducer is reliable to seal and is convenient to install.
Description
Technical field
The utility model relates to retarder, be specifically related to a kind of with combined sealing structure can three placements retarder.
Background technique
At present, general retarder has only a kind of mounting point, and the choice was less when the user used, if when the design retarder, it is designed to front, side all can settles, will aggravate to destroy the sealing reliability of retarder.
Summary of the invention
The purpose of this utility model is: provide a kind of with combined sealing structure can three placements retarder, its sealing is reliable, can three arrangements, easy for installation.
Technical solution of the present utility model is: in the casing of being made up of upper box lid, following case lid input shaft, transition driven shaft, transition driving shaft and output shaft are installed, input shaft, transition driven shaft, transition driving shaft and output shaft are coupled to each other by gear and annex and constitute retarder, it is characterized in that: installation shaft carrier ring on the bearing of input shaft and output shaft, several relief holes evenly distribute on the bearer ring, even several draining holes of distribution on the bearing support of upper box lid and following case lid, the relief hole on the bearer ring communicates with draining hole on the bearing support.
Wherein, there is the grinding undercut that inwardly digs dark 2-3 millimeter, wide 4-5 millimeter in the draining hole on the bearing support, and grinding undercut is positioned at the fitting surface place with bearer ring, and draining aperture grinding undercut is communicated with the relief hole of bearer ring.
Wherein, on input shaft and output shaft, combined sealing structure is installed, combined sealing structure comprises primary seal structure and secondary sealing configuration, the primary seal structure is made up of with L type seal ring one O RunddichtringO, the O RunddichtringO is installed on the L type seal ring, and secondary sealing configuration is the dust ring that has sealing lip.
Settle base surface in installation front, the front of following case lid,, right flank arrangement base surface is installed, the bolt hole of the arrangement of supplying is all arranged on the base surface at the right flank of following case lid at the left surface installation left surface arrangement base surface of following case lid.
The utlity model has following advantage: 1, this retarder can three placements, and is easy for installation; 2, adopt combined sealing structure, sealing is reliable; 3, unexpected high pressure appears during high speed rotating in axle easily, can prevent high pressure infringement annex through relief hole, and the effect of circulation flushing dead angle is arranged.
