Abstract
The utility model relates in a kind of speed changer with drain pan by axle sleeve, and it has sleeve body 21, and there is a step hole 22 centre of sleeve body, during work aperture fixing in by driven gear, in macropore is fixing by oil sealing.Contacted by driven gear with the lining by sleeve body aperture inwall and axle sleeve in the lining and to offer drain pan 23 on the end face, drain pan one end Tongli is by the macropore of axle sleeve, and the other end to end face and mission case is communicated with.By this drain pan is set, can allow and be flowed back to smoothly in the mission case by the lubricant oil of axle sleeve in entering, be maintained normal level by the lubricating oil pressure in the axle sleeve in making, not leak out from seal ring, so just can satisfy the requirement of installation, can satisfy the requirement of sealing again.
Description
Technical field
The utility model belongs to the automotive transmission technical field, and specific design is a kind of to be had in the speed changer of oil draining function by axle sleeve.
Background technique
At present seen Fig. 1 by axle sleeve structure in the speed changer, it has sleeve body 11, and there is step hole 12 centre of sleeve body, in aperture is used for fixing by driven gear, sealed circle in macropore is used for fixing.Do not had oil draining function by axle sleeve in this structure, by axle sleeve, because lubricant oil does not have the return flow line, by in the axle sleeve, sealed circle leaked the lubricant oil in the mission case from the lining to cause lubricant oil in lubricant oil accumulated in the lining is pumped into by driven gear shaft.
Summary of the invention
The purpose of this utility model is at the prior art above shortcomings, provides in a kind of speed changer with drain pan by axle sleeve, can satisfy the requirement of installation, can satisfy the requirement of sealing again.
Technical solution of the present utility model is to be contacted by driven gear with the lining by sleeve body aperture inwall and axle sleeve in the lining to offer drain pan on the end face, and drain pan one end Tongli is by the macropore of axle sleeve, and the other end to end face and mission case is communicated with.By this drain pan is set, allow and flowed back to smoothly in the mission case by the lubricant oil of axle sleeve in entering, maintained normal level by the lubricating oil pressure in the axle sleeve in making, do not leak out from seal ring, so just can satisfy the requirement of installation, can satisfy the requirement of sealing again.
Description of drawings
Fig. 1 is by the structural representation of axle sleeve in having now;
Fig. 2 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 2, have in the speed changer of drain pan and had sleeve body 21 by axle sleeve, there is a step hole 22 centre of sleeve body, contacted by driven gear in the little hole wall of this step hole 22 and axle sleeve and lining that to have radius on the end face be 1 millimeter semicircular arc groove 23, semicircular arc groove 23 1 ends are communicated by the macropore of axle sleeve with the lining, the other end to end face is communicated with mission case, reaches the purpose of draining.
Claims (1)
