Description
Technical Field
The utility model belongs to the barring machine field of making, concretely relates to vertical worm gear barring machine with separation and reunion braking system.
Background
Turning gear refers to that before starting the motor, the motor is rotated by manpower for several circles to judge whether the load (i.e. mechanical or transmission part) driven by the motor is blocked and the resistance is increased, so that the starting load of the motor is not increased and the motor is not damaged (i.e. burned). Therefore, after the machine is stopped for one shift (8 hours), when the machine is restarted, the machine needs to be turned, along with the development of science and technology, the size of the machine is larger and higher, the load is higher and higher, the time and labor are more wasted through the traditional manual turning, therefore, the electric turning machine is quite popular at present, the use of the turning machine in the field of motor maintenance is wider and wider, when the output shaft of the motor is judged to be damaged, the output shaft of the motor is driven to rotate through the electric turning machine, the machine is stopped and repaired once the surface of the output shaft is damaged, the electric turning machine is continuously started to turn the machine after being repaired, meanwhile, the dial indicator is used for judging the circular runout of the repaired output shaft, when the machine is stopped midway in the process, because the shaft system of the large motor has larger size, the abrasion error and the slight abrasion are easily generated during the work, and the, that is, once the electric barring machine stops, the original shafting system turning with the barring machine will slightly rotate forwards or backwards according to the difference of the gravity center of the electric barring machine, at this time, the electric barring machine has stopped, but the driving gear in the electric barring machine and the driven gear sleeved on the output shaft of the motor are still in a meshed state, so the electric barring machine will bear the circumferential force caused by the micro rotation of the output shaft of the motor due to inertia or uneven gravity at the moment of rest (it can be understood that the electric barring machine acts as a locking device for the motor at this time), the service life and transmission precision of the driving gear in the past electric barring machine will be affected, especially when the motor in the ship is barring, the size of the motor in the ship is larger, and in consideration of the working space during barring, the vertical worm and gear barring machine is generally used for main barring power components, the driving part of the vertical worm and gear barring machine is a worm, and the worm rotates to drive the driven gear on the motor to rotate, so that the output shaft of the motor is driven to rotate, if the barring process is required to be stopped immediately, the situation is inevitably generated, because the size of the vertical worm and gear barring machine is relatively small, the worm is meshed with the gear on the output shaft of the motor when the worm is static, and when the force transmitted by the output shaft of the motor is received, the service life of the worm, the assembly structure of the vertical worm and gear barring machine and the working precision of the barring machine can be affected for a long time, and therefore the development of the vertical worm and gear barring machine capable of realizing clutch braking is very complex in actual requirement.

Principle of operation
When the utility model is used, the state position of the clutch brake system is firstly judged, namely whether the worm wheel 1 and the clutch gear 2 are jointed for synchronous motion or not, synchronous motion is realized between the worm wheel 1 and the clutch gear 2 through the friction plate, when the bulge on the clutch gear 2 is arranged in the groove of the worm wheel 1, the friction plate outside the bulge on the clutch gear 2 can be contacted with the friction plate inside the groove of the worm wheel 1, synchronous motion is realized under the action of friction force (principle and friction plate clutch), an operator can determine the position of the clutch gear 2 by controlling the telescopic rod 6 through the handle 13, the telescopic rod 6 is pushed to move forwards to ensure that the clutch gear 2 is jointed with the worm wheel 1 and moves synchronously with the worm wheel, meanwhile, the clutch gear 2 can be meshed with the driven gear 3, when the clutch gear 2 and the worm wheel 1 synchronously move, the driven gear 3 is driven to rotate, at the moment, the brake connecting rod 9 moves backwards, one end of the brake connecting rod 9 drives the first transmission connecting rod 17 and the second transmission connecting rod 18 to contract, and simultaneously drives the first brake connecting rod 16 and the second brake connecting rod 19 to respectively move towards the center of the driven gear 3, so that the first arc-shaped brake friction plate 15 and the second arc-shaped brake friction plate 20 are respectively far away from the driven gear 3;
when an operator pulls out the telescopic rod 6 to retreat so that the clutch gear 2 is separated from the worm wheel 1, the clutch gear 2 cannot rotate along with the worm wheel 1 at the moment, the clutch gear 2 cannot be meshed with the driven gear 3, the driven gear 3 loses power source and is subjected to inertial motion, the brake connecting rod 9 moves forwards under the driving of the balance connecting rod 7 at the moment, one end of the brake connecting rod 9 drives the first transmission connecting rod 17 and the second transmission connecting rod 18 to be opened, and simultaneously drives the first brake connecting rod 16 and the second brake connecting rod 19 to respectively move towards the edge of the driven gear 3, so that the first arc-shaped brake friction plate 15 and the second arc-shaped brake friction plate 20 are respectively contacted with the driven gear 3, and the driven gear 3 is braked under the action of friction;
it is worth noting that in order to realize that the clutch gear 2 can just realize braking on the driven gear 3 when being separated from the driven gear 3, the movement distance of the first brake connecting rod 16 and the second brake connecting rod 19, the gear thickness of the driven gear 3 and the length of each strip-shaped hole on the balance connecting rod 7 are the same, the clutch gear 2 is meshed with the driven gear 3 when the protrusion on the telescopic rod 6 is positioned at one end, close to the center of the balance connecting rod 7, of the strip-shaped hole on the balance connecting rod 7 (as shown in fig. 3), and the clutch gear 2 is separated from the driven gear 3 when the protrusion on the telescopic rod 6 is positioned at one end, far away from the center of the balance connecting rod 7.
