Description

Impeller with starting and cooling functions

Technical Field

The utility model relates to an impeller technical field specifically is an impeller of area start-up cooling function.

Background

The impeller refers to a disk provided with moving blades, is a component of an impulse turbine rotor, and can also be a general name of the disk and the rotating blades arranged on the disk. The impellers can be classified according to shape and opening and closing conditions.

The impeller function that current vertical axis general purpose machine used only is for cooling usefulness, and the start-up connection needs solitary start-up cup rather than linking to each other and reconnect the flywheel and just play the function of start-up, and a plurality of spare parts stack can play the effect that starts with cooling, and a plurality of spare parts assembly is loaded down with trivial details simultaneously, and the cost is higher.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cooling function's impeller is started in area to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an impeller of cooling function is started in area, includes impeller body, impeller start jack catch, blade and flywheel start jack catch, the positive inboard of impeller body evenly is provided with the impeller start jack catch, the positive edge of impeller body evenly is provided with the blade, the central point symmetry welding at the impeller body back has the flywheel to start the jack catch.

The impeller body and the impeller starting clamping claw and the blades are of an integrated structure.

The impeller body, the impeller starting clamping jaws and the blades are all made of modified PP materials.

The impeller body drives the flywheel to rotate through the flywheel starting claw.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model has the functions of starting and cooling, reduces the number of parts, optimizes the assembly process, and directly reduces the cost of parts and labor; meanwhile, the impeller body directly drives the flywheel to rotate by starting the clamping jaw through the flywheel without an intermediate connecting piece, so that the relative motion of the impeller body and the flywheel is reduced, the assembly process is further optimized, and the connection between the impeller body and the flywheel is simpler and more reliable.

In the figure: 1-an impeller body; 2-starting the claw by the impeller; 3-a blade; 4-flywheel start dog.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: an impeller with a starting and cooling function comprises an impeller body 1, an impeller starting claw 2, blades 3 and a flywheel starting claw 4.

The inner side of the front face of the impeller body 1 is uniformly provided with impeller starting clamping jaws 2, the edge of the front face of the impeller body 1 is uniformly provided with blades 3, the center of the back face of the impeller body 1 is symmetrically welded with flywheel starting clamping jaws 4, the impeller body 1 drives a flywheel to rotate through the flywheel starting clamping jaws 4, when the engine hand-pull starter is started, a pull disc pawl of the engine hand-pull starter flies out and is clamped on the impeller starting clamping jaws 2, so that the impeller body 1 is driven to rotate, the blades 3 are driven to rotate at the same time, and the rotating blades 3 are used for dissipating heat to achieve a cooling effect; meanwhile, a starting clamping groove is formed in the flywheel, the flywheel starting clamping jaw 4 on the back face of the impeller body 1 is matched with the starting clamping groove formed in the flywheel, when the impeller body 1 rotates, the flywheel starting clamping jaw 4 on the back face of the impeller body 1 is matched with the starting clamping groove formed in the flywheel to drive the flywheel to rotate, then the crankshaft is driven to rotate, and finally the starting purpose is achieved.

Wherein, impeller body 1 and impeller start jack catch 2 and blade 3 and are the integral type structure, set impeller body 1 and impeller start jack catch 2 and blade 3 into the integral type structure, simplified assembly process.

Wherein, impeller body 1, impeller start-up jack catch 2 and blade 3 all adopt modification PP material to make.

The inner side of the flywheel starting claw 4 is provided with a curved surface groove, and when the impeller body 1 rotates, the flywheel starting claw 4 on the back of the impeller body 1 is in contact with a starting clamping groove arranged on the flywheel, so that the contact area between the flywheel starting claw 4 and the flywheel is increased, and the impact caused in the starting moment can be reduced.

The working principle is as follows: when the manual engine starter is used, when the manual engine starter is started, a pull disc pawl of the manual engine starter flies out and is clamped on the impeller starting claw 2, so that the impeller body 1 is driven to rotate, the blades 3 are driven to rotate, and the rotating blades 3 dissipate heat to achieve a cooling effect; the flywheel starting claw 4 on the back of the impeller body 1 is matched with the starting clamping groove arranged on the flywheel to drive the flywheel to rotate, and then the crankshaft is driven to rotate, and finally the starting purpose is achieved, so the impeller body 1 has the starting and cooling functions, meanwhile, the impeller body 1 directly drives the flywheel to rotate through the flywheel starting claw 4, an intermediate connecting piece is not needed, the relative motion of the impeller body 1 and the flywheel is reduced, the assembling process is further optimized, and the impeller body 1 is simpler and more reliable to connect with the flywheel.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
