How does tank turret work

The end of the arm 92 more remote from shaft 86 tapers so that arm 92 can rotate about the axis of shaft 86 without interference with bracket Intermediate the ends of arm 92 are downward projecting legs 94 pivotally connected to the midsection of lower arm 96 by means of pin Tines are formed at one end of lower arm 96 and the lower portion of shaft 86 passes between these tines, which are somewhat similar to tines 64 in FIG. Circular rod protrudes through cross-sectionally elongate apertures in tines and also through shaft Lower arm 96 swings upward to raise shaft 86 without binding pin against either end of apertures On the opposite side of pin 98 from tines is handle assembly rotatably mounted to lower arm 96 so that the handle assembly will rotate about its longitudinal axis.

Handle assembly is allowed to rotate by a pair of rings and fitting into grooves at the neck portion of handle body in the handle assembly, ring being directly above lower arm 96 and ring being directly below arm Rings and prevent axial movement of handle assembly Protruding from neck portion of handle assembly is an axially translatable rod which has a rounded end bearing against the underside of upper arm Near the bottom of handle body is pin upon which is swingably mounted palm switch handle Palm switch is connected to translatable rod by link and by link pins and Handle body has a tab whose aperture registers with aperture on palm switch handle when the palm switch handle is swung against handle body A dowel or lock pin may be inserted through the registered apertures to lock the palm switch handle in its position against handle body When palm switch handle is swung counterclockwise from its FIG.

The motion of lower arm 96 lifts shaft 86 so that gear 93 engages the teeth of turret ring such as that shown in FIG. Handle assembly , arms 92 and 96, and shaft 86 form a crank by which gear 93 can then be driven. When shaft 86 is lifted from its FIG. Switch 90 performs an electrical function analogous to that of switch element 70a in FIG. I wish it to be understood that I do not desire to be limited to the exact details of the methods and constructions of my invention shown and described herein, because obvious modifications may occur to those skilled in the relevant art without departing from the spirit and scope of the following claims.

What is claimed is: 1. A manually operable crank mechanism mounted to an interior surface of a tank hull at a location where a tank turret rotatably mounts to the hull, the crank mechanism comprising: a bevel gear for engaging a circular array of teeth on an inner peripheral surface of the turret;.

The mechanism of claim 1 wherein the translating means comprises a lever whose one end is pivoted to the handle, the lever extending generally vertically along and diverging away from the handle, whereby the handle and lever can be grasped simultaneously with one hand by a human tank driver.

The mechanism of claim 1 including a tension spring connected between the longer leg of the L-shaped arm and the bifurcated arm, the spring biasing the bifurcated arm toward the longer leg.

The mechanism of claim 1 wherein the one end of the bifurcated arm is pivotally connected to the shorter leg of the L-shaped arm, the remaining end of the bifurcated arm has the tines, the translatable rod engages the bifurcated arm adjacent the one end, and the tines support weight of the shaft and the gear, whereby the weight of the shaft and the gear will depress the translatable rod.

The mechanism of claim 1 including a switch to control an electrical means for disabling a motorized drive train from traversing the turret, the switch comprising a slip ring rotatably mounted to the shaft extension between the bracket and the bifurcated arm, the slip ring being axially fixed relative to the shaft extension and movable relative to the bracket to make and break electrical contact with the bracket.

A mechanism for traversing a turret on a vehicle hull, comprising: a bracket fixed to the hull;. The mechanism of claim 6 including a sleeve concentric with the central axis, the sleeve passing through the bracket and the first arm and having radially extending flanges at both ends of the sleeve for holding the first arm against the bracket. The mechanism of claim 6 wherein the pivotal connection comprises an elongate projection extending from one of the arms to the other of the arms, the projection pivotable about a pin on the other arm.

The mechanism of claim 6 wherein the arms and the handle travel together in a rotational path as a unitized assembly about the central axis and wherein the bracket is clear of the rotational path of the unitized assembly. The mechanism of claim 6 including an electrical means for disabling a motorized drive train from traversing the turret, a switch mechanism for actuating and deactuating the electrical means, the switch mechanism comprising an annular projection on the shaft, the projection movable with the shaft along an axial translational path along the central axis, the switch mechanism further comprising a switch having a lever extending into the translational path of the annular projection and a switch contact operable by movement of the lever to open or close an electrical path within the electrical means.

USA en. A destroyed turret will lock and will not rotate until repaired. A damaged turret rotates at a greatly reduced traverse speed.

The act of rotating the turret decreases the accuracy of the main gun. So to fire with the most accuracy, you should stop rotating the turret and allow the aiming circle to shrink to its minimum diameter before firing the gun. World of Tanks Wiki Explore.
