Abstract
The utility model discloses a crankshaft box, crankshaft box are equipped with the cylinder liner installation department, have seted up the cylinder jacket hole on the cylinder liner installation department, and the periphery of cylinder liner installation department is equipped with recessed wind channel structure, and cylinder liner installation department external connection has first accessory plate for wind channel structure forms first wind channel hole on the cylinder liner installation department. Adopt the utility model discloses, because the cylinder liner installation department is equipped with first accessory plate outward for the wind channel structure becomes poroid first wind channel hole, makes the cooling air that the recoil starter produced blow through from first wind channel hole, makes the cooling wind energy obtain effectual utilization, has improved the radiating effect of cooling air, can reduce peripheral temperature by a wide margin.
Description
Technical Field
The utility model relates to a gasoline engine part, especially a crankshaft box.
Background
The crankcase body of the gasoline engine consists of an aluminum alloy case body and a cast iron cylinder sleeve, wherein the crankcase body is used for storing lubricating oil. Usually, the crankcase is made of aluminum alloy by die casting, and the shape of the crankcase is related to the overall arrangement of the engine and the capacity and power of engine oil. In the existing design (as shown in figure 1), a concave air channel structure is arranged on the periphery of a cylinder sleeve hole of a crankshaft box body, and the air channel structure is open, so that the problem that the cooling air generated by a recoil starter is not concentrated when the cooling air blows through the crankshaft box body, and the cooling effect of the cylinder sleeve is poor is caused.
Disclosure of Invention
The utility model aims to provide a: to the not good problem of crankcase cooling effect among the prior art, provide a crankcase that cooling effect is good.
In order to realize the purpose of the utility model, the utility model provides a following technical scheme:
the utility model provides a bent axle box, bent axle box are equipped with cylinder liner installation department, have seted up cylinder jacket hole on the cylinder liner installation department, and the periphery of cylinder liner installation department is equipped with recessed wind channel structure, and cylinder liner installation department outer coupling has first accessory plate for wind channel structure forms first wind channel hole on the cylinder liner installation department.
Adopt above-mentioned technical scheme's utility model, because the cylinder liner installation department is equipped with first accessory plate outward for the wind channel structure becomes poroid first wind channel hole, makes the cooling air that recoil starter produced blow through from first wind channel hole, makes the cooling wind energy obtain effectual utilization, has improved the radiating effect of cooling air, can reduce peripheral temperature by a wide margin.
Furthermore, a second auxiliary plate is connected outside the cylinder sleeve mounting portion, the second auxiliary plate and the first auxiliary plate are arranged in an opposite mode, and a second air duct hole is formed in the cylinder sleeve mounting portion of the second auxiliary plate. The second auxiliary plate increases the quantity of the air duct structure, can effectively cool and improve the cooling effect.
Furthermore, two rows of second air duct holes arranged in parallel are formed on the second auxiliary plate. Under the condition that the thickness of the second auxiliary plate allows, a plurality of rows of second air duct holes can be additionally arranged so as to improve the cooling effect.
Further, there are three second air duct holes in each row. The number of the second air duct holes can be adjusted according to a specific structure.
Furthermore, the first air duct holes are arranged in parallel, and the second air duct holes are also arranged in parallel. The parallel arrangement is convenient for the processing of the air duct hole.
Further, there are six first air duct holes. The number of the first air duct holes can be adjusted according to a specific structure.
Furthermore, five cylinder head locking and mounting holes are formed in the cylinder sleeve mounting portion, and the cylinder head locking and mounting holes are uniformly distributed and located on the vertex of the pentagon. Five cylinder head locking mounting holes are arranged, so that the distance between the cylinder head locking mounting holes is reduced, and the torque deformation of each hole is reduced; when the gasoline engine runs durably, the locking strength is improved, and the problem of cylinder flushing air leakage caused by thermal deformation of the cylinder sleeve is effectively solved.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: because the cylinder sleeve installation part is externally provided with the first auxiliary plate, the air channel structure becomes a porous first air channel hole, the cooling air generated by the recoil starter blows through the first air channel hole, the cooling wind energy is effectively utilized, the heat dissipation effect of the cooling air is improved, and the peripheral temperature can be greatly reduced.
