Snitzl's Drive Mechanisms

Hi All, Thought I'd add this topic to illustrate a few of the drive mechanism's I've been working on and also add new one's that are still in the pipeline. To start, here's what I believe to be an original design for a compensated motor bogie, but I'm sure there has to be similar design's out there.

Here are the components for a compensated chassis for 'De Snitzlton', a small vertical boilered 0:4:0 locomotive that requires drive to both axle's due to the transverse cylinder arrangement.

The drive axle mounted on the left is fixed, while the gearbox mounted on the bevel gear drive shaft is allowed to rotate, the axle holes in the chassis are oversize to allow a small amount of rotation.

The bevel gear drive shaft fitted.

A retaining plate holds the bevel gear drive shaft in place.

Here is an earlier design used on a L.S.W.R. Elec Set Motor Bogie. This bogie has two brass gearbox's, one of which is allowed to rotate a little, the central brass block retains the drive axle.

The same system is used for a tram motor bogie.

Thanks for Looking.

Hi All, A few images of the mechanism developed for a scratchbuilt Sharman type steam traverser. The traverser is DCC operated and runs just as you would a loco, the drive and motor are part of the traverser.

The gearbox housing is machined from brass and will be mounted on the underside of the traverser.

12-IMG_4616.jpg.17129d8364647b2c8367cdd246aff8ff.jpg

Most of the gear's came from the scrap box, some needed a slight modification's.

13-IMG_4618.jpg.6c79845855a6d9dc9b2ec3953c1b60d1.jpg

Just checking that the gears mesh OK.

14-IMG_4622.jpg.1033cc9b6d2480973fba99e9c2d2c132.jpg

The gearbox is now ready for mounting.

The rail wheels pictured left are free running.

16-IMG_4682.jpg.fd0c85861471d7927d7a9b18c728fa94.jpg

The large gear on the right has it's bore tapped 2BA for a length of stud, this gear provides the drive.

17-IMG_4685.jpg.177daa8b2b1666fb68f81ec3c97e2345.jpg

Here's the completed mechanism ready for fitting.

 

Thanks for Looking.

Had this crazy idea about building a few animated wagon's that would run on DCC for Fun Town's market.

Chassis gearbox milled from solid brass with a motor gearbox asseembly from the bay.

19-20-IMG_1994.JPG.44c560ab3029c40f405c16478e0a2611.JPG

The first wagon will be a steam driven 'Ice Cream Wagon' -  with transverse cylinders.

20-28-IMG_2047.JPG.f047c79300203ebefb30cf6c18976cbe.JPG

Outer body is a good slide fit on the chassis.

21-34-IMG_2060.JPG.49ccc3581f01060ef871757cce5eaaf6.JPG

A few moving parts added to the outside of the wagon.

22-52-IMG_2086.JPG.c6dec0268393d1972fc65e9a8cc9408c.JPG

Wagon still needs a a decoder and paintjob, but works fine on 5 volts DC.
