Description

A kind of engine flywheel

Technical field

The utility model relates to a kind of engine flywheels.

Background technique

Existing flywheel typically directly carries out hardness using bolt and is fixedly connected, in crankshaft when being fixedly connected with crankshaft Lack damping element with flywheel, and damping element can not be arranged in existing connection type, cause flywheel when slightly trembleing to crankshaft It impacts.

Utility model content

The technical problem to be solved by the present invention is in view of the above drawbacks of the prior art, provide a kind of engine Flywheel.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of engine flywheel is constructed, the flywheel Including wheel disc, the signal panels parallel and coaxially connected with the wheel disc and it is fixedly connected with the wheel disk center and the signal disk center Fixing axle, the wheel disc circumference be equipped with igniting gear ring, the signal panels circumference be equipped with signal teeth, the fixing axle first end be equipped with for Crankshaft insertion connection insertion hole, the fixing axle second end be equipped with the block crankshaft block disk, first face of block disk with should Crankshaft end-face abuts, block disk the second face surface and the second face of wheel disc flush, the block disk be equipped with for song The first fixed hole that axial end is fixedly connected, the diameter of the signal panels are less than the diameter of the wheel disc, which is equipped with The the first vibration isolation rubber sleeve that can be sheathed on outside the crankshaft, which, which is installed with, protrudes from the signal panel surface Counterweight ring.

In engine flywheel described in the utility model, which also pads to be equipped with and abut with the crankshaft end-face It is fixed logical to be additionally provided with second opposite with the first fixed hole position on the circle rubber damping pad for round rubber damping pad Hole.

In engine flywheel described in the utility model, which is counter sink.

In engine flywheel described in the utility model, the fixing axle be taper tubular fixing axle, the fixing axle it is small Diameter end is fixedly connected with the signal disk center, and the bigger diameter end of the fixing axle is fixedly connected with the wheel disk center, insertion Kong Weiyuan Shape is inserted into hole, which runs through the signal panels.

In engine flywheel described in the utility model, which is adhered to the wall that inserts in the hole, And the first vibration isolation rubber length sleeve is less than or equal to the insertion hole depth.

The engine flywheel for implementing the utility model is had the advantages that and is flown using the engine of the utility model When wheel, when flywheel is fixed on crankshaft end, crankshaft need to be only inserted into the first vibration-absorbing rubber sleeve for being sheathed on and inserting in the hole In cylinder, the first fixed hole then is passed through using fixing bolt and is spirally connected later with the fixation of the threaded hole of crankshaft end-face, can be realized The fixation of flywheel.Further, by wheel disc and signal panels that igniting gear ring and signal teeth is separately positioned, it can avoid mutual It interferes.By the way that counterweight ring is arranged in wheel disc periphery, increase flywheel turns inertia.By between crankshaft and the wall that inserts in the hole Pad sets the first vibration isolation rubber sleeve, can be by the first vibration isolation rubber sleeve slowing down vibration to song when flywheel has slight trembling The transmitting of axis.

Detailed description of the invention

Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:

Fig. 1 is the cross-sectional structure schematic diagram of the utility model engine flywheel side；

Fig. 2 is the positive structure schematic of the utility model engine flywheel.

Specific embodiment

It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer Type embodiment is described in further detail.

As shown in Figure 1, 2, in the engine flywheel first embodiment of the utility model, the flywheel 1 include wheel disc 2, with The parallel and coaxially connected signal panels 3 of the wheel disc 2 and the fixing axle for being fixedly connected with 2 center of wheel disc and 3 center of signal panels 4,2 circumference of wheel disc be equipped with igniting gear ring 5,3 circumference of signal panels be equipped with signal teeth 6,4 first end of fixing axle be equipped with for The insertion hole 7 of crankshaft insertion connection, 4 second end of fixing axle are equipped with the block disk 8 of the block crankshaft, 8 first face of block disk It is abutted with the crankshaft end-face, the 8 second face surface of block disk and the 2 second face flush of wheel disc, which, which is equipped with, uses In the first fixed hole 9 being fixedly connected with crankshaft end-face, the diameter of the signal panels 3 is less than the diameter of the wheel disc 2, the insertion Pad is equipped with the first vibration isolation rubber sleeve 10 that can be sheathed on outside the crankshaft in hole 7, which, which is installed with, protrudes from The counterweight ring 11 on 3 surface of signal panels.

Using the utility model engine flywheel 1 when, when flywheel 1 is fixed on crankshaft end, only crankshaft need to be inserted Enter to be sheathed on insertion hole 7 in the first vibration isolation rubber sleeve 10 in, then using fixing bolt pass through the first fixed hole 9 it It is spirally connected afterwards with the fixation of the threaded hole of crankshaft end-face, the fixation of flywheel 1 can be realized.Further, pass through wheel disc 2 and signal panels 3 Igniting gear ring 5 and signal teeth 6 is separately positioned, it can avoid interfering between each other.By the way that counterweight ring is arranged in 2 periphery of wheel disc 11, increase by 1 rotator inertia of flywheel.The first vibration isolation rubber sleeve 10 is set by padding between crankshaft and insertion 7 inner wall of hole, in flywheel 1 when having slight trembling, can transmitting by from 10 slowing down vibration of the first vibration isolation rubber sleeve to crankshaft.

Further, which also pads the round rubber damping pad 12 for being equipped with and abutting with the crankshaft end-face, should Second fixed hole 13 opposite with 9 position of the first fixed hole is additionally provided on round rubber damping pad 12.By being inserted into 7 bottom of hole pad sets round rubber damping pad 12, plays better effectiveness in vibration suppression.

Preferably, which is counter sink.

In the present embodiment, which is taper tubular fixing axle 4, the miner diameter end of the fixing axle 4 and the signal panels 3 centers are fixedly connected, and the bigger diameter end of the fixing axle 4 is fixedly connected with 2 center of wheel disc, which is circular inserting hole 7, The signal panels 3 are run through in the insertion hole 7.

Specifically, the first vibration isolation rubber sleeve 10 is adhered to 7 inner wall of insertion hole, and the first vibration isolation rubber sleeve 10 Length is less than or equal to 7 depth of insertion hole.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
