Abstract
The utility model discloses a crankshaft of an engine, which is characterized in that the crank (1) is connected with an extension bar (2). Because the utility model adopts that an extension crankshaft is connected with the extension bar by the crank in a screw thread connection mode, a production plant does not need to open a mould again, and therefore, manufacture difficulty of the crankshaft can be reduced, and investment is small; because the extension bar can be adjusted according to requirements, the utility model also has the characteristic wide range of application.
Description
(1). technical field
The utility model belongs to engine art, particularly a kind of device that is used for the crankshaft structure of motor.
(2). background technique
At present,, often motor need be improved, when need on bent axle, increasing build-up member or, engine crankshaft must being extended because the build-up member position of bent axle changes for satisfying market demand.This method usually increases the manufacture difficulty of bent axle, and because the change of bent axle makes factory's die sinking again, investment is big.
(3). summary of the invention
The purpose of this utility model provides a kind of engine crankshaft.It can enlarge the using scope of bent axle, reduces the manufacture difficulty of bent axle, invests little.
For reaching above-mentioned purpose, the utility model comprises crank, it is characterized in that crank and extension bar are with being threaded.
The end that crank is connected with extension bar is provided with outside thread, or in its end internal thread is set.
Extension bar is step-like.
The utility model owing to adopt will extend bent axle with crank and extension bar with being threaded, make factory not need die sinking again, can reduce the manufacture difficulty of bent axle, invest little.Because extension bar can be adjusted as required, therefore also have the wide characteristics of using scope.
Below in conjunction with accompanying drawing the utility model is described further.
(4). description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is an another kind of structural drawing of the present utility model.
(5). embodiment
Referring to Fig. 1.Microcephaly end at crank 1 is provided with outside thread, and the step-like long bolt 2 that adds is provided with the internal thread corresponding with crank 1, and crank 1 is connected with extension bar 2.
Referring to Fig. 2.Microcephaly end at crank 1 is provided with internal thread, and the step-like long bolt 2 that adds is provided with the outside thread corresponding with crank 1, and crank 1 is connected with extension bar 2.
According to the engine model needs, the length of extension bar and each chi head are set and constitute this engine crankshaft, the required component of assembling on the bent axle of this motor promptly can satisfy the engine modifications needs.
