Description
Technical field
The utility model relates to a kind of Novel main reducing gear lubrication system architecture, belongs to auto manufacturing, is applicable to highway engineering driving axle of dump truck.
Background technique
The lubricating system of penetrating bridge main speed reducer mainly contains two kinds: splash system lubrication and positive drive type lubrication.For the good road vehicle of applying working condition, because road conditions are good, the speed of a motor vehicle is high, the mode of structure of splash system lubrication that what penetrating bridge main speed reducer adopted usually is; But for the highway car using industrial and mineral comparatively severe, because road conditions are poor, the speed of a motor vehicle is low, penetrating bridge main speed reducer adopts the mode of structure of pressure lubrication usually.
The structure of the forced lubricating system of the penetrating bridge main speed reducer on current domestic highway engineering dump truck market is similar, namely installation pressure lubrication oil pump is covered in active cylindrical gear shell, oil pump is connected with drive bevel gear and obtains power, oil leab is directly put at shell and is cast out, and structure as shown in Figure 1.Mainly there is following problem in this structure:
1, oil leab directly casts out on housing, and casting difficulty is large, complex process;
2, cast oil duct not easy to clean, the residual sand in using process in oil duct causes the wearing and tearing of lubricated surface;
3, when vehicle ramp angle strengthens, pasta declines, and pump oil mass is rare, affects lubrication effect.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel main reducing gear lubrication system architecture, and it is simple that it has structure, easily realizes, repair demolition is convenient, reduces manufacture cost, uses the features such as reliable, pump oil mass is sufficient.
The technical solution of the utility model is achieved in that a kind of Novel main reducing gear lubrication system architecture, it is characterized in that: reducing gearbox front end is fixedly connected with fore shell, the oil leab of straight UNICOM is had bottom the bottom of reducing gearbox and fore shell, oil leab front end bottom fore shell is connected with transition net assembly, pressure lubrication oil pump is fixedly connected on fore shell by oil pump base, the input shaft of pressure lubrication oil pump is connected with drive bevel gear, oil pump base has oil duct, pressure lubrication oil pump is communicated with drive bevel gear by oil duct, pressure lubrication oil pump is connected with by external oil pipe with the upper end of fore shell, drive bevel gear, initiatively cylindrical gear shaft are arranged in the enclosure interior that fore shell and reducing gearbox form, initiatively cylindrical gear shaft is connected with the interaxial differential assembly in reducing gearbox, initiatively cylindrical gear shaft there is initiatively cylindrical gears, initiatively cylindrical gear shaft front end is spacing by the active cylindrical gear shaft fore bearing on fore shell, initiatively cylindrical gears engages with drive bevel gear, fore shell has oil duct with active cylindrical gear shaft contacting point, and the oil duct the other end connects external oil pipe.
Good effect of the present utility model is it by external oil pipe, oil pump base with organic oiling road, casts the structure of straight oil duct, replace the casting oil duct of the complexity on conventional construction middle shell, there is structure simple, easily realize, repair demolition is convenient, reduce manufacture cost, use the features such as reliable, pump oil mass is sufficient.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as Fig. 1, shown in 2, a kind of Novel main reducing gear lubrication system architecture, it is characterized in that: reducing gearbox 8 front end is fixedly connected with fore shell 5, the oil leab 7 of straight UNICOM is had bottom the bottom of reducing gearbox 8 and fore shell 5, oil leab 7 front end bottom fore shell 5 is connected with transition net assembly 4, pressure lubrication oil pump 2 is fixedly connected on fore shell 5 by oil pump base 3, the input shaft of pressure lubrication oil pump 2 is connected with drive bevel gear 6, oil pump base 3 has oil duct, pressure lubrication oil pump 2 is communicated with drive bevel gear 6 by oil duct, pressure lubrication oil pump 2 is connected with by external oil pipe 1 with the upper end of fore shell 5, drive bevel gear 6, initiatively cylindrical gear shaft 10 are arranged in the enclosure interior that fore shell 5 forms with reducing gearbox 8, initiatively cylindrical gear shaft 10 is connected with the interaxial differential assembly 12 in reducing gearbox 8, initiatively cylindrical gear shaft 10 there is initiatively cylindrical gears 11, initiatively cylindrical gear shaft 10 front end is spacing by the active cylindrical gear shaft fore bearing 9 on fore shell 5, initiatively cylindrical gears 11 engages with drive bevel gear 6, fore shell 5 has oil duct with active cylindrical gear shaft 10 contacting point, and the oil duct the other end connects external oil pipe 1.
Initiatively cylindrical gear shaft 10 is drilled with oil channel hole, oil channel hole aims at initiatively cylindrical gear shaft fore bearing 9, initiatively cylindrical gears 11 and interaxial differential assembly 12 respectively, pressure lubrication oil pump 2 obtains power by drive bevel gear 6, lubricant oil is inhaled from the bottom pump of penetrating bridge main speed reducer, lubricant oil is through oil channel 7, oil pump base 3, external oil pipe 1, fore shell 5, initiatively cylindrical gear shaft 10, main cylinder cylindrical gear shaft fore bearing 9 is lubricated by the oilhole in active cylindrical gear shaft 10, the initiatively fitting surface of cylindrical gears 11 and active cylindrical gear shaft 10, each rotatable engagement face in interaxial differential assembly 12 and gears meshing face, oil leab 7 is in the lowermost end of penetrating bridge main speed reducer, ensure that ransaxle oil leab 7 when all angles work all is positioned at below lubricant oil liquid level, filter screen assembly 4 is arranged on oil pump base 3, by the contaminant filter in lubricant oil, ensure the clean of each frictional fit surface lubrication oil.
This forced lubricating system structure, by casting straight oil duct 7, oil pump base 3, external oil pipe 1 by mode of structure external for oil leab, the oil channel structure of the complexity of original forced lubricating system is simplified, greatly reduce the difficulty of producing and processing, effectively reduce because oil leab cleaning is clean and cause the failure mode of parts depreciation, can ensure that there is good lubricating condition each position of penetrating bridge main speed reducer under various severe operating mode simultaneously.
