Abstract
A circulating system with a compulsory inner lubricating structure comprises a pump, a bracket, an external oil pipe, an internal oil pipe, an axle housing, a supporting shaft and a hub reduction mechanism, wherein, the external oil pipe is connected with an internal oil pipe in the axle housing; and the internal oil pipe is connected with an internal oil duct of the supporting shaft in the hub reduction mechanism. Because the utility model adopts the structure, except the self-lubrication of an ordinary driving axle, the lubricating oil of the hub reduction mechanism and the lubricating oil of a central speed reducer are integrated; a built-in wet-type brake is arranged in the hub reduction mechanism; the high temperature is generated during braking; the system is favorable for the condition of reducing local high oil temperature, and achieves entire thermal balance; in addition, a section of external oil pipe is arranged outside the driving axle, so that the system is favorable for heat emission of the lubricating oil greatly, and the oil temperature of the driving axle is ensured within a normal working range.
Description
Technical field
The utility model relates to a kind of lubricating fitting of engineering machinery ransaxle.
Background technique
At present, the gear in the engineering machinery loader ransaxle must be lubricated in the course of the work.Ransaxle generally is divided into two parts and is lubricated separately: the one, and hub reduction mechanism lubricates; The one, central main reducing gear part lubricated.Hub reduction mechanism is by flooding system lubrication, injects an amount of lubricant oil in the mechanism of wheel limit, stirs oil sump when the gear of wheel side speed reducer structure rotates during work, and formation is splashed, and carries out train and lubricates, and wheel limit bearing similarly carries out splash lubrication.Central reducer unit part lubricated has two kinds of approach: the one, and the driven helical gear by high speed rotating stirs oil sump, and formation is splashed, and the gear in the central reducer unit is lubricated.Another is that the central reducer unit carriage is cast with inner oil duct, the lubricant oil that will splash through oil leab enter into splash lubrication less than bearing portion, the bearing of central reducer unit is lubricated.Because central reducer unit and hub reduction mechanism are two independently unit, the high situation of local oil temperature can appear.
Summary of the invention
The purpose of this utility model provides a kind of by increasing a pump and oil duct at central reducer unit, make the lubricant oil of central reducer unit force in the course of the work to lead to hub reduction mechanism flow of lubricant, form a circulation loop, improve the lubrication state of ransaxle, reduce the high circulatory system of local oil temperature with lubricating structure in the pressure.
The purpose of this utility model is achieved in that by pump, carriage, external oil pipe, internal oil pipe, axle housing, supporting axle, hub reduction mechanism to be formed, external oil pipe connects the internal oil pipe in the axle housing, the inside oil duct of internal oil pipe connecting wheel side speed reducer structure internal support axle.
Because the utility model adopts said structure, except that the self-lubrication of general ransaxle, hub reduction mechanism and central reducer unit two-part lubricant oil are formed one; Built-in wet brake is arranged in hub reduction mechanism, when braking, produce high temperature, and this system helps reducing the high situation of local oil temperature, reach whole thermal equilibrium; One section external oil pipe is arranged in addition in the ransaxle outside, greatly help the lubricant oil heat radiation; Guarantee that ransaxle oil temperature is in normal range of operation.
Description of drawings
Fig. 1 is a structural drawing of the present utility model; Fig. 2 is that Figure 1A is to partial view;
Fig. 3 is the central reducer unit sectional view; Fig. 4 is a hub reduction mechanism sectional view.
1 central reducer unit, 2 input flanges, 3 pumps, 4 carriages, 5 external oil pipes, 6 internal oil pipe, 7 axle housings, 8 supporting axles, 9 hub reduction mechanisms among Fig. 1.
Embodiment
Embodiment: this system is made up of central reducer unit 1, input flange 2, pump 3, carriage 4, external oil pipe 5, internal oil pipe 6, axle housing 7, supporting axle 8, hub reduction mechanism 9, external oil pipe 5 connects the internal oil pipe 6 of axle housing interior 7, the supporting axle 8 in the internal oil pipe 6 connecting wheel side speed reducer structures 9.During ransaxle work, pump 3 is delivered to external oil pipe 5 with input flange 2 high speed rotating of central reducer unit 1 with the lubricant oil in central reducer unit 1 and the carriage 4 inner oil ducts, and the inside oil duct through internal oil pipe 6 and supporting axle 8 enters into hub reduction mechanism 9 again.Make hub reduction mechanism 9 oil levels be higher than the oil level of central reducer unit 1, lubricant oil subtracts mechanism 9 through supporting axle 8 endoporus and axle housing 7 endoporus trailing wheel limits and flows to central reducer unit 1, again through the inlet of the inside of carriage 4 oil duct to pump 3, forms a complete lubricating circulatory system.Fig. 1 is seen in the circulation loop signal.
This circulatory system forms one with hub reduction mechanism and central reducer unit two-part lubricant oil except that the self-lubrication of general ransaxle; Built-in wet brake is arranged in hub reduction mechanism, when braking, produce high temperature, and this system helps reducing the high situation of local oil temperature, reach whole thermal equilibrium; One section external oil pipe is arranged in addition in the ransaxle outside, greatly help the lubricant oil heat radiation; Guarantee that ransaxle oil temperature is in normal range of operation.
