Abstract
The utility model discloses a kind of integrated type balance shaft mechanism of vertical type single-cylinder diesel engine, comprise the body of vertical type single-cylinder diesel engine, trunnion shaft, also comprise the flat position of trunnion shaft, the flat position of described trunnion shaft is positioned at one end of trunnion shaft, the flat position of described trunnion shaft and trunnion shaft are monolithic construction, and the flat position of described trunnion shaft is provided with fluting, and described fluting connects oil hydraulic pump.The utility model integrated type balance shaft mechanism is simple for structure, component reduce, cost reduces.
Description
Technical field
The utility model relates to diesel engine arts, especially a kind of integrated type balance shaft mechanism of vertical type single-cylinder diesel engine.
Background technique
At present, the balance shaft mechanism of vertical type single-cylinder diesel engine, is generally divided into two kinds.That cost is also high, and reliability is bad by increasing the transmission shaft supported by bearings at both ends in addition, the split-type structural then connected with trunnion shaft, this complicated structure.Another kind adopts gear and transmission shaft integral type, and the mode of structure then connected with trunnion shaft, the gear of this structure and transmission shaft are integral type structure, and the diameter of transmission shaft can do larger, and reliability is secure, and structure is simpler.But due to gear and transmission shaft integral type, in manufacturability, difficulty is comparatively large, and manufacture cost is high; When connecting with exterior part, well do not seal, easy leakage of oil simultaneously.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of integrated type balance shaft mechanism of simple for structure, vertical type single-cylinder diesel engine that good reliability, cost are low.
The purpose of this utility model is achieved in that a kind of integrated type balance shaft mechanism of vertical type single-cylinder diesel engine, comprise the body of vertical type single-cylinder diesel engine, trunnion shaft, also comprise the flat position of trunnion shaft, the flat position of described trunnion shaft is positioned at one end of trunnion shaft, the flat position of described trunnion shaft and trunnion shaft are monolithic construction, and the flat position of described trunnion shaft is provided with fluting, and described fluting connects oil hydraulic pump.
Described body attachment tooth gear chamber cover, described gear chamber cover is arranged balance axis hole.
Oil sealing is provided with between described gear chamber cover and the flat position of trunnion shaft.
The reduced thickness of described balance axis hole is to 30-35mm.
The beneficial effects of the utility model are that the flat position 5 of being slotted by trunnion shaft end, is directly connected with peripheral device structure-oil hydraulic pump 7 by adopting integrated type trunnion shaft 3, reach the object that auxiliary power exports; And the thickness of the gear chamber cover 8 connected with body 1 reduces, the gear chamber cap bore 9 of assembling trunnion shaft is processed easier; Meanwhile, at trunnion shaft 3 end assembling oil sealing 6, the effect of sealing is reached.This integrated type balance shaft mechanism is simple for structure, component reduce, cost reduces.

Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
As shown in Fig. 1 ~ Fig. 5, the integrated type balance shaft mechanism of the utility model vertical type single-cylinder diesel engine comprises vertical single cylinder diesel body 1, and integrated type trunnion shaft 3, the flat position 5 of the slotted trunnion shaft in trunnion shaft 3 end, and flat position 5 is through special heat treatment process, and intensity is guaranteed.Fig. 4-5 is plan view and the side view of gear chamber cover 8, and gear chamber cover 8 connects with body, and the gear chamber cap bore 9 of assembling trunnion shaft is equipped with gap with trunnion shaft 3, and thickness is thin, processing simple.Integrated type trunnion shaft 3 is assemblied in vertical single cylinder diesel body 1, and two ends are supported by bearing 2 and bearing 4, and integrated type trunnion shaft 3 is assemblied in body 1, and can flexible rotating.The flat position 5 of trunnion shaft connects with peripheral hardware mechanism-oil hydraulic pump 7, by the rotation of trunnion shaft 3, drives oil hydraulic pump 7 to work.Oil sealing 6 in trunnion shaft 3 end by interference fit, is prevented internal body machine oil from spilling, reaches the effect of sealing.The reduced thickness of balance axis hole, to 30-35mm, reduces 20mm than the existing balance shaft mechanism gear chamber cap bore thickness having installed split type trunnion shaft, reduces material and be about 0.5kg.
The flat position that integrated type trunnion shaft of the present utility model is slotted by end, directly connects with peripheral device structure oil hydraulic pump, reaches the object that auxiliary power exports; On the other hand, the position of gear chamber cap bore is originally owing to needing to arrange a pair for installing the bearing of the flat position of trunnion shaft, thus its thickness is thicker, after adopting integrated type trunnion shaft, the flat position of trunnion shaft is cantilever structure, supports, therefore without the need to special bearing, gear chamber cap bore thickness is reduced, makes the processing of the gear chamber cap bore of assembling trunnion shaft easier; And in trunnion shaft end assembly lube envelope, reach the effect of sealing.
The flat position of trunnion shaft 5 is through special heat treatment process, and make in connecting with peripheral device structure-oil hydraulic pump 7 and using, reliability is well ensured.
All the other structures are all known according to other formations of cylinder head of the present utility model and operation to those skilled in the art, are not described in detail here.
Although illustrate and described embodiment of the present utility model; those of ordinary skill in the art is to be understood that: can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and aim; scope of the present utility model limited by claim and equivalent replacement thereof; in the improvement etc. done without creative work, all should be included within protection domain of the present utility model.
