Abstract
The utility model provides a mounting structure of an intermediate drive gear for a front axle. The mounting structure of the intermediate drive gear for the front axle comprises an intermediate transmission shell, a vertical shaft sleeve shell, an intermediate transmission gear, a bearing and a gear mounting end block, wherein the gear mounting end block comprises a round tube and a flange arranged at one end of the round tube; a radial raised ring is arranged in the middle of the inner surface of the center hole of the gear mounting end block, so that the center hole is divided into a bearing mounting position and an oil seal mounting position; the bearing is arranged at the bearing mounting position; an oil seal is arranged in the oil seal mounting position; the intermediate transmission gear is arranged in the bearing and is inserted from a mounting hole in the side surface of the vertical shaft sleeve shell; and the intermediate transmission shell, the flange and the vertical shaft sleeve shell are fixed together by a bolt. The mounting structure of the intermediate drive gear for the front axle is easy to mount and maintain, and is firm and reliable; abrasion on the gear is reduced; and a cavity in the vertical shaft sleeve shell can be separated from a cavity in the intermediate transmission shell by the oil seal, so that the phenomenon that an intermediate differential mechanism assembly is jammed or damaged due to reduction of lubrication oil is prevented.
Description
Technical field
The utility model belongs to automobile and field of agricultural machinery, relates to a kind of mechanical transmission sealing configuration, particularly a kind of mounting structure of propons intermediate drive gear.
Background technique
For reducing costs, improve product competitiveness in the market, fraction horsepower section farm tractor front axle intermediate drive gear means of fixation is as shown in Figure 4 in the market.Intermediate drive gear is arranged on by bearing in the lateral opening of vertical shaft sleeve cylinder shell, and intermediate drive gear inserts vertical shaft sleeve cylinder shell from the side.The intermediate transmission outer shaft sleeve being connected with intermediate drive gear has intermediate transmission housing, and intermediate transmission housing is connected on the lateral opening of vertical shaft sleeve cylinder shell.
Adopt this structure, if be interference fit between bearing and vertical shaft sleeve cylinder shell, when breaking down to pull down, intermediate drive gear changes or when maintenance, because vertical shaft sleeve cylinder shell inner space is little, cause bearing to be removed very difficult, greatly increased difficulty and the time of reprocessing operation.If bearing and vertical shaft sleeve cylinder shell are Spielpassung, with tractor net cycle time, change, intermediate drive gear wear extent is more.Spielpassung causes in the course of the work, and intermediate drive gear there will be mobile phenomenon in vertical shaft sleeve cylinder shell.Result reduces power transmission efficiency on the one hand, strengthens on the other hand gear wear, reduces gear life.
Model utility content
The technical problem that the utility model solves has been to provide a kind of rational in infrastructure reliable, is convenient to the mounting structure of the propons intermediate drive gear of assembling maintenance.
To achieve these goals, the technological scheme that the utility model is taked is:
The mounting structure of described propons intermediate drive gear, comprise intermediate transmission housing, vertical shaft sleeve cylinder shell, intermediate drive gear and bearing, described intermediate drive gear inserts described vertical shaft sleeve cylinder shell from the side, it is characterized in that: also comprise gear installation end block, described gear is installed end block and is provided with center hole, described intermediate drive gear is arranged in described center hole by described bearing, and end block is installed for described intermediate transmission housing, described gear and described vertical shaft sleeve cylinder shell is removably fixed together.
Described gear is installed end block and is comprised pipe portion, and described pipe portion one end is provided with flange, and the other end inserts described vertical shaft sleeve cylinder shell, and described flange is between described intermediate transmission housing and described vertical shaft sleeve cylinder shell.
Described flange is provided with for described gear is installed to the dismounting tapped hole that end block ejects.
Described gear is installed in end block and is provided with oil sealing.
Described center hole internal surface is provided with radial convex loop, and described radial convex loop is divided into bearing installation position and oil sealing installation position two-part by described center hole, and described oil sealing installation position is near described flange.
Described bearing and described center hole interference fit.
Adopt technique scheme, bearing is installed end block by gear and is fixed in vertical shaft sleeve cylinder shell, installs or keeps in repair very easy.Bearing and gear are installed end block interference fit, solid and reliable, have reduced the wearing and tearing of gear.Oil sealing is set and the cavity in the cavity in vertical shaft sleeve cylinder shell and intermediate transmission housing can be kept apart, prevent that lubricant oil from flowing between the two, with differential assembly in the middle of guaranteeing, can not occur stuck or damage because lubricant oil reduces.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technological scheme.
As shown in Figure 1 to Figure 3, the utility model provides a kind of mounting structure of propons intermediate drive gear 2, comprises intermediate transmission housing 5, vertical shaft sleeve cylinder shell 1, intermediate drive gear 2, bearing 3 and gear installation end block 4.Gear is installed the flange 7 that end block 4 comprises pipe portion 11 and pipe portion 11 one end are set, and the center hole 8 that gear is installed end block 4 is provided with a circle radial convex loop 9 in the middle part on surface therein, thereby center hole 8 is divided into bearing installation position 12 and oil sealing installation position 13 two-part.Oil sealing installation position 13 is near flange 7, and bearing installation position 12 is at the another side of center hole 8, near vertical shaft sleeve cylinder shell 1.
When needs are safeguarded or change intermediate drive gear 2, the bolt of side mounting hole periphery is unloaded, can complete the dismounting of intermediate transmission housing 5.Then in above-mentioned dismounting tapped hole 10, screw in bolt, bolt withstands on the flat surface of vertical shaft sleeve tube shell 1, gear is installed to end block 4 and from above-mentioned vertical shaft sleeve pipe 1, eject, and realizes the dismounting of gear installation end block 4.Pull down again bearing 3 and gear, just can gear or bearing 3 be safeguarded or be changed.Described bearing 3 and gear installation end block 4 interference fit have reduced the wearing and tearing of intermediate drive gear 2, have extended the life-span of intermediate drive gear 2.
