Sliding mesh gearbox is a transmission system that consists of various sets of gears and shafts that are arranged together in an organized fashion and the shifting or meshing of different gear ratios is done by the sliding of gears towards the right and left over the splined shaft with the help of a gear lever operated by the driver. The outer surface of this shaft is made splined so that the gears can easily slide over this shaft in order to mesh with the appropriate gear.

The gears of the main shaft slide over the shaft to mesh with the appropriate gears of the layshaft so that the required gear ratio is obtained. It takes more time and money to replace the gears if the gearbox fails but in constant mesh gearbox only dog clutches are to be replaced at failure which takes less time and money. The gears of this shaft have internally splined grooves and the outer surface of this shaft is made splined so that the gears can easily slide over the shaft.The gears of main shaft slides over the shaft to mesh with appropriate gears of lay shaft so that required gear ratio is obtained.ii) Gears:Usually two types of gears were used in sliding mesh gearbox. It is also used in cars like the Ford Model T.\nPrior to the introduction of the synchromesh gearbox in 1928 by General Motors, a constant mesh box was used in motorbikes."}}]}.

To shift between different speeds using a sliding-mesh gearbox, the gears on the main shaft are shifted right or left for meshing them with the appropriate gears on the counter shaft (this is where the phrase shifting gears comes from). Like this post? Due to rotation of lay shaft other gears of lay shaft also rotates as all the gears in lay shaft are rigidly fixed including the reverse gear. Thank you Peter for your help - especially during the massive Rogers outage! Hey, I am Rajkumar. Sliding gear is a power-transmission system in which any given pair of gears is engaged by sliding one axially into mesh with the other. Disadvantages of Sliding Mesh Gearbox: Only spur gears can be used as gears are not in constant mesh-like constant-mesh gearbox in which helical or herringbone gears can be used. Are you experiencing transmission troubles or have questions about your vehicles transmission? That gave way to the synchro-mesh gearbox, a unit that has many similarities to its constant-mesh predecessor since the gears are always engaged. Second Gear provides lower torque and higher speed than First Gear.3. A sliding-mesh gearbox may be mechanically efficient, but the noise it generates when changing gears, and the difficulty that was involved when changing gears left much to be desired. Since the gear of the main shaft is in a continuous mesh with the appropriate gear of the continuous shaft, the selection of 1, 2, 3, 4, and reverse gears is achieved with the proper pair sliding and traps of the dog clutch. Nothing but good things to say about Mister Transmission. Automotive gearboxes provide the opposite, ie an increase in the output shaft speed with a decrease in torque (overdrive). A stem or lever is used to hold the ring gear and maintain its rotation on the brake plate. If a driver makes a bad change in gears, any damage that may occur will be limited to the dog clutch. Hence, for a given load, the force will be spread out better than with a spur gear, resulting in less wear on individual teeth. In this gearbox, the sliding mesh was paired with continuously added gears and new shifting devices called dog clutches were introduced. I highly recomend this place. An idler gear exists between the gear of the main shaft and the gear to form the reverse gear. Thank you everyone, you did awesome!!
