Abstract
The utility model relates to a diesel engine component, and particularly to a crankshaft of a double-cylinder air-cooled diesel engine. The crankshaft of the double-cylinder air-cooled diesel engine comprises a main shaft (1) which is fixedly connected with two crank arms (2) that are parallel with each other. A crank shaft pin (4) is provided between the inside parts of the tops of the two crank arms (2). The lower end of each crank arm (2) is provided with a balancing block (3). The crank arms (2) and the balancing blocks (3) are in an integral structure. The diameter (A) (phi) of the crank shaft pin (4) is 38-41 mm. The width (B) of the crank pin (4) is 53-56 mm. The thickness (C) of each crank arm (2) is 34-38mm. According to the crankshaft of the double-cylinder air-cooled diesel engine, the diameter (A) of the crank pin, the width (B) of the crank pin and the thickness of the crank arm in the prior-art crankshaft are improved. Furthermore an integral structure is adopted for the crank arm and the balancing block, and therefore the crankshaft of the double-cylinder air-cooled diesel engine has the following advantages: improved strength, better operation stability, effective prevention for crankshaft fracture accident, better reliability and longer service life.
Description
Technical field
The utility model relates to a kind of diesel engine part, especially relates to a kind of double cylinder wind cooling diesel bent axle.
Background technique
Because the crank of diesel engine is the gyration center that departs from bent axle, therefore, diesel engine is when work, and bent axle is in non-equilibrium state, can produce vibration.The bent axle of traditional double cylinder wind cooling diesel, because size design is unreasonable, and its equilibrium block is to add to weld by locating stud to be fixed together with crankweb, the smoothness of operation and the reliability of diesel engine are relatively poor, and the crankshaft breakdown accident takes place easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of smoothness of operation and reliability double cylinder wind cooling diesel bent axle preferably is provided.
The purpose of this utility model is achieved in that a kind of double cylinder wind cooling diesel bent axle, it comprises main shaft, be fixedly connected with two mutual parallel crankwebs on the main shaft, be provided with crank pin between described two crankweb inside top, the crankweb lower end is provided with equilibrium block, it is characterized in that: described crankweb and equilibrium block are monolithic construction.
The described crank pin diameter of axle is Ф 38 ~ Ф 41mm, and the crank pin width is 53 ~ 56mm, and crank thickness is 34 ~ 38mm.
Compared with prior art, the beneficial effects of the utility model are:
A kind of double cylinder wind cooling diesel bent axle of the utility model improves the design size of crank pin diameter of axle A, crank pin width B and the crank thickness of former bent axle, and crank arm and equilibrium block adopt monolithic construction, strength of crankshaft has obtained reinforcement, the smoothness of operation of bent axle is better, prevented the generation of the fracture accident of bent axle effectively, its reliability is better, and working life is longer.
Description of drawings
Fig. 1 is the structural representation of the utility model double cylinder wind cooling diesel bent axle.
Wherein:
Main shaft 1, crankweb 2, equilibrium block 3, crank pin 4.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of double cylinder wind cooling diesel bent axle, it comprises main shaft 1, be fixedly connected with two mutual parallel crankwebs 2 on the main shaft 1, described two crankweb 2 inside top are provided with crank pin 4, crank pin 4 interconnects with crankweb 2, and crankweb 2 lower ends are provided with equilibrium block 3, and crankweb 2 is a monolithic construction with equilibrium block 3.
In order to improve strength of crankshaft, design size to crank pin diameter of axle A, crank pin width B and the crank thickness of former bent axle is improved, crank pin 4 diameter of axle A of the present utility model are Ф 38 ~ Ф 41mm, and crank pin 4 width B are 53 ~ 56mm, and crankweb 2 thickness C are 34 ~ 38mm.
Claims (2)
1. double cylinder wind cooling diesel bent axle, it comprises main shaft (1), be fixedly connected with two mutual parallel crankwebs (2) on the main shaft (1), be provided with crank pin (4) between described two crankwebs (2) inside top, crankweb (2) lower end is provided with equilibrium block (3), it is characterized in that: described crankweb (2) is a monolithic construction with equilibrium block (3).
2. a kind of double cylinder wind cooling diesel bent axle according to claim 1 is characterized in that: described crank pin (4) diameter of axle (A) is Ф 38 ~ Ф 41mm, and crank pin (4) width (B) is 53 ~ 56mm, and crankweb (2) thickness (C) is 34 ~ 38mm.
