adobe resource syncronizer This is a topic that many people are looking for. khurak.net is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, khurak.net would like to introduce to you Synchronizer Operation Explained. Following along are instructions in the video below:
“Basic operation. The synchronizer performs three basic tasks the first task synchronizer must synchronize the the rotational speed of two rotating objects the second task the synchronizer must be able mechanically lock the two rotating objects together and finally if the object cannot be synchronized the synchronizer must block or prevent the mechanical locking mechanism from attempting to engage this prevents gear grinding. Which is also known as gear clash. The synchronizer hub has several functions that apply to it one is it synchronizer hub splines to the shaft.
It splines through the splines in the center of the hub and fits onto this shaft. This way the hub rotates with the shaft at all times. And when we pull the synchronizer hub off the shaft will not only see the splines. But will notice that it s recessed on that side and on the other side.
There s a raise in the center. That means. The synchronizer hub goes on one way and actually it ll fit more than one way. But it won t function properly.
Now if we take a closer look at the hub will see the splines for the synchronizer sleeve to slide on then there s a slot for the synchronizer keys and the hole in the center is for a synchronizer spring. The synchronizer sleeve has special functions and attributes of its own the sleeve is designed to slide onto the synchronizer hub through the splines in the center. Once you get lined up properly. It should slide smoothly back and forth onto the hub.
The splines are specially designed the one in the center. Here has a special cutout in the middle for the synchronizer key on both sides the splines have been removed..
So you can line that up properly onto the hub. If you look closely at the teeth or the pointed part of the teeth. You ll see a back cut. This is designed to hold the sleeve onto the gear.
The outside of the sleeve has a cutout for the shift fork take a look on each side of that cutout. You ll see that the edge is a little bit different for each one in this picture. One edge has a thin line on it this designates. Which way the sleeve fits onto the hub.
You can also have tapers or different designations on the edge of the sleeve. So make sure you put it on the hub. Correctly the free spinning speed gear has several attributes of its own the angle cut teeth or helical cut teeth give it a good quiet operation with great load carrying capabilities the number of these teeth determine the gear ratio. The small straight cut.
Teeth known as clutching teeth are used to engage the synchronizer sleeve with the speed gear. The conical face surface is used for the synchronizer blocker ring. Allowing synchronization of this gear and the polished surface in the center is used for a set of needle bearings. So the free spinning gear and rotate freely on a shaft.
This can demonstrate how the synchronizer locks. The gear to the shaft first i ll slide the sleeve on to the synchronizer hub..
Then i ll take the free spinning speed gear and remove the needle bearings. I ll slide the needle bearings on to the shaft. They write on a polished surface next. I ll slide the speed gear onto the shaft over the needle bearings.
Here. You ll be able to see that the speed gear free spins on the shaft. Now if i slide the sleeve towards a speed gear the clutching teeth will lock the sleeve to the speed gear. Therefore a locking speed gear to the shaft wheel the sleeve back and the free spinning speed gear spins freely and slide the sleeve forward again and once again it s locked the clutching teeth on the sleeve are designed to engage with the clutching teeth on the free spinning gear.
When the sleeve moves towards the free spinning gear the clutching teeth will lock together this will lock the sleeve to the gear. The cut back on to the clutching teeth help prevent the gear separation. If the gear is not properly engaged with the sleeve. Then the clutching teeth won t lock and this could cause jumping out of gear or improper engagement.
This is a synchronizer blocker ring. It works in conjunction with the sleeve and the synchronizer keys. It s job is to synchronize a speed of two rotating objects if these objects are unable to synchronize. It has a second job which is to block the sleeve to prevent gear grinding between the sleeve.
And the speed gear. The blocker ring has a reverse conical surface on the inner edge..
This conical surface fits perfectly on the conical surface of the speed gear. There s also clutching teeth that line up between a speed gear. And the blocker ring. The inner edge of the block or ring is created friction asst.
This one has grooves to create friction between a blocker ring and speed here this one uses a friction style sintered metal surface and this one uses a fiber metal or fiber product. Much like a brake shoe and here s an unusual design. This is a double cone design with friction material on both sides synchronize a key which looks like this fits into the synchronizer hub. There are three locations.
There s a key for each one. There s also a cutout on the blocker ring with a synchronizer key fits into the special cutout. When they re put together. They look like this and take a look at them in the transmission or transaxle.
You ll see that the synchronizer rocks back and forth. It s got a little bit of movement. Because the difference in the size of the cutout on the blocker ring and the size of the key now when you rotate the entire shaft. You ll see that the blocker rings rotate with the shaft and the synchronizer therefore they rotate at shaft.
The key also fits in a special cutout on the sleeve. When you re put together they look like this and when the shifter is shifted the sleeve pushes on the key and slides. It over to lock. The gear.
Blocker ring and synchronizer together this animation shows that the speed gear is rotating faster than the blocker ring and synchronizer as a synchronizer sleeve starts to move over the blocker ring pushes against the speed gear and synchronize the speed of the two objects. Then the sleeve can move over and lock the two together watch this really close. I need to point out a few things here s the speed gear. Clutching t.
s and here is the synchronizer blocking ring t. s and right there is the synchronizer sleeve. Now when i start this up you re gonna see the sleeve start to move to the left now when that happens blocker ring teeth are gonna start to synchronize up with the teeth of the speed gear. I use a strobe light to stop everything and you ll see the speed gear and the blocking teeth line up.
And then the sleeve will move over and lock everything together and watch carefully watch the sleeve and watch the synchronizer blocker ring sleeve move over look at the blocker ring and moved it back that will asleep. Oh look at the pucker ring and engagement now they re different speeds. They re sinking and lock one more time take a look they re sinking and one more time sink and lock it perfect operation. ” .
