Abstract
The utility model discloses a reinforced diesel engine body device, which consists of a water inlet, a double wall water jacket, reinforcing ribs and a push rod chamber, wherein a water jacket is arranged on the lower part between an outer double wall of a diesel engine body and a cylinder body on the middle part, the double wall water jacket is arranged in the water jacket, and one side of the double wall water jacket is provided with two water inlets; and the central lines of the outer double wall of the diesel engine body and the cylinder body on the middle part are vertical, at least six reinforcing ribs are arranged in a square shape to form at least one cavity, and the push rod chamber is formed in the cavity. The device has reasonable design, and changes the water inlet position to reinforce and cool the engine body by increasing the reinforcing ribs in the engine body.
Description
Technical field
The utility model relates to internal combustion (IC) engine airframe, especially a kind of reinforced diesel engine body device.
Background technique
At present, China internal-combustion engine of middle low power industry producer is numerous, dog-eat-dog, the supporting producer of each main frame is in order to improve the margin of power of machinery, power to diesel engine is had higher requirement, diesel engine manufacturer improves power in order to meet the demands by enlarging cylinder diameter, stroke or measures such as supercharging, charge inter cooling.The utilization of these technology has had further raising to the quality and the performance demands of parts and components of diesel engine, and the cooling effect of diesel engine is also had higher requirement.
Summary of the invention
Quality, the increase strength of machine body of the utility model in order to improve component by rational design, provides a kind of intensity reinforced diesel-engine body, adopts the body of hollow double wall, improves resistance to flexure, is suitable for the diesel-engine body of multi-cylinder diesel engine.
The utility model adopts following technological scheme for achieving the above object: water intake, double wall water jacket, stiffening rib, push rod chamber constitutes, and the below is provided with water jacket between the cylinder body at diesel engine external body double wall and middle part, the double wall water jacket is set in the water jacket, and a side of double wall water jacket is provided with two water intakes; Center line is vertical between the cylinder body at diesel engine external body double wall and middle part, is square at least six stiffening ribs are set, and constitutes at least one cavity, and push rod chamber is set in the cavity.
Beneficial effect: the reinforced diesel-engine body of this intensity is the improvement design under the prerequisite that does not change the diesel-engine body functional structure, except that cast blank and water jacket sand removal hole site change again, processing is identical with body before improving with installation, adjust water jacket sand removal hole site man-hour and just can realize by improving the structural modification casting mould, adding.By changing blahk structure intensity, improved the bending resistance torsional property of diesel-engine body accordingly, satisfied diesel engine power and promoted the back the body performance demands.After the water jacket water pipe of waistband end face (the dry type body is to the cylinder sleeve bottom surface) changes water jacket under changing into diesel-engine body lateral inflow pipe from the body end face to cylinder sleeve, increased the volume of water, reduce water and entered the preceding expenditure and pressure effect of cylinder sleeve water cavity, after the water inlet changes following macropore into by top aperture, not only can guarantee abundant cooling to cylinder sleeve, and can improve cylinder sleeve hydraulic pressure on every side, thus increase the water flow of body to cylinder cap, improve cooling effect.Can improve the bending resistance twisting strength after changing the push rod chamber of diesel-engine body another side into double wall, but change the mounting type of tappet, be unfavorable for the diesel engine maintenance.Adopt gusset to separate Placement and strengthen push rod chamber intensity, promptly played and strengthened the antitorque effect of body bending resistance, do not change the mounting type of diesel engine tappet again, the place adds T-shaped stiffening rib at the push rod chamber screw, the push rod chamber inside and outside wall coupled together push rod chamber is separated into a plurality of small box by a big cavity, made things convenient for the installation and the maintenance of diesel engine.Reasonable in design, body increases stiffening rib, changes the position, water inlet, strengthens, cools off body.
