It is not easy to operate.
Utility model content
In order to solve the problems in the existing technology, flywheel can be fixed, dismantle the utility model by providing one kind
Flywheel extractor.
In order to achieve the above object, the utility model proposes technical solution are as follows: a kind of flywheel extractor, for by flywheel
It is separated with crankshaft, the flywheel top is equipped with threaded hole and boot disk, and the center line of the threaded hole and crankshaft is located at same axis
On line, the boot disk in a ring, and is located at threaded hole periphery, and boot disk is equipped with several grooves, the flywheel extractor packet
It includes retainer ring, help pull a cart and mandril, the retainer ring internal diameter is matched with starting dish external diameter, and retainer ring inner wall is equipped with several convex blocks, described
Convex block is matched with groove, and retainer ring side is equipped with handle, and retainer ring can cover in boot disk, and will by the chimeric of convex block and groove
Boot disk is blocked, and described to help pull a cart cylindrical, one end is equipped with the external screw thread that cooperate with the threaded hole, inner wall equipped with internal screw thread,
Mandril outer wall is equipped with the external screw thread with screw-internal thread fit of helping pull a cart, and one end of helping pull a cart can be inserted into threaded hole, and drawing is protruded into mandril one end
It is threadedly coupled in set and with helping pull a cart, the mandril end can resist crankshaft.
Above-mentioned technical proposal is further designed to: further including extension bar, described mandril one end is equipped with connecting hole, reinforcing
Bar can be inserted into connecting hole.
Described extension bar one end is equipped with block.
The mandril protrudes into tapped through hole one end equipped with frustum, and the frustum diameter is gradually reduced from top to bottom.
The handle is equipped with annular knurl.
The utility model has the following beneficial effects:
The utility model blocks the boot disk of flywheel by retainer ring, and flywheel is fixed, and helps pull a cart and screws in flywheel threaded hole,
Crankshaft one end is withstood by the mandril in helping pull a cart, and constantly rotation mandril makes top cover that flywheel be driven to move up, and realizes crankshaft and flywheel
Separation holds retainer ring handle on the other hand when use, turns mandril on the other hand, and retainer ring also gives the rotation of mandril while fixing flywheel
Turn to provide by means of force, can easily separate flywheel with crankshaft.
The flywheel extractor structure of the utility model is simple, easy to use.

Embodiment
A kind of flywheel extractor of the present embodiment, including retainer ring 1, help pull a cart 2, mandril 3 and extension bar 4,1 structure of retainer ring is as schemed
Shown in 1, the circle body including annular, circle body inside is equipped with several convex blocks 11, and circle body side is equipped with handle 12, and help pull a cart 2, mandril, 3 and
The structure of extension bar 4 is as shown in Fig. 2, help pull a cart 2 cylindrical, and one end is equipped with external screw thread, and inner wall is equipped with internal screw thread, and mandril 3 is equipped with
With the external screw thread for 2 screw-internal thread fits of helping pull a cart, and in can screwing in and helping pull a cart, 3 one end of mandril is equipped with connecting hole, and extension bar 4, which can be inserted into, to be connected
It connects in hole, convex block is equipped in 4 one end of extension bar, can prevent extension bar 4 from deviating from from connecting hole, mandril 3 protrudes into 2 one end of helping pull a cart and sets
There is frustum, frustum diameter is gradually reduced from top to bottom.
For the flywheel extractor of the present embodiment for separating flywheel 5 with crankshaft 6, flywheel structure is as shown in Figure 3 and Figure 4, flies
5 tops are taken turns equipped with threaded hole 51 and boot disk 52, the center line and threaded hole 51 of threaded hole 51 and crankshaft 6 are located at same axis
