Device for pumping oil from the side gearboxes tank
(57) Abstract:The invention relates to armored technique, in particular to devices lubrication system and hydraulic control transmission. The technical result is to ensure reliable starting of the engine in the winter and increasing protection of the tank against high-precision weapons. The invention consists in that the device is provided with an additional malooschutimoy pump with electric drive and bypass valve installed between the oil tank and the main inputs malooschutimoy pumps. The electrical circuit of the drive is enabled the timer associated with the gauge tachometer engine tank. 1 Il. The invention relates to the field of armored vehicles, in particular to the device, lubrication system and hydraulic control transmission.The known device system pumping oil from gearboxes (see Object M. Technical description and operating instructions. KN. second. - M.: Voenizdat, 1975, 581 S. (S. 251-264); Object 434. Technical description and operating instructions. KN. second. - M.: Central research Institute of Information, 1974, S. 187-196).Of the analogues studied as a prototype single system pumping oil from boxes per. C. 251-264) containing miklosiceva pumps, piping and oil tank.When you stop the tank engine stops, the oil circulating in the hydraulic power transmission. In Carter's side gearboxes remains about 20 litres of oil. At the next start of the engine, this oil provides additional resistance to cranking. Especially it grows in winter. To facilitate starting and to reduce the load on the starter, the oil channel boosters transmissions before Parking in winter conditions pump in the sump lubrication system. For complete removal of oil from the side gearboxes must be made 2 times its pumping when the engine is running with a five minute break between cycles of pumping.However, in terms of the use by the enemy of high-precision automated weapons for such a long time needed for pumping oil, does not meet tactical requirements. In order to avoid detection and destruction homing ammunition thermal imaging seeker tank must be installed in the shelter and the engine stopped immediately. The existing pumping system does not meet this important castigates without pumping the oil from the gearbox through the fault of the personnel.The objective of the proposed device is to ensure reliable starting of the engine in the winter and increasing protection of the tank against high-precision controlled automatic weapons of the enemy.This task is achieved by a device for pumping oil from the side gearboxes tank containing maclatchie pumps, piping and oil tank, equipped with an additional malooschutimoy pump with electric drive and bypass valve installed between the oil tank and the main inputs malooschutimoy pumps, and the electrical circuit of the drive is enabled the timer associated with the gauge tachometer engine tank.The drawing shows a diagram of the device.Device for pumping oil from the side gearboxes contains the left gearbox 1, the left malooschutimoy pump 2, tank 3, milosocivi pump 4, the right gearbox 5, right malooschutimoy pump 6, the bypass valve 7, malooschutimoy pump 8 with the actuator 9, a timer 10, the gauge tachometer 11.The operation of the device is as follows.When killing the engine gauge tachometer water 9 meloodiatega pump 8. Since the left and right maclatchie pumps 2 and 6 don't work because of stop of the engine, pumping out oil from the side gearboxes 1 and 5 provides malooschutimoy pump 8, which pumps the oil in the oil tank 3. After two minutes time relay 10 disables the on-Board voltage from the actuator 9, the pumping of oil stops.When the engine is running the bypass valve 7 prevents air leaks from the oil tank 3.The use of the proposed device for pumping oil from the crankcase gears when engine shutdown (including and improper actions of the driver) will significantly increase the reliability of the power plant and power transmission tank, as well as increase its protection from high-precision controlled automatic weapons.The simplicity of the proposed device for pumping oil from gearboxes will allow you to quickly and easily implement the present invention in the course of mass production and modernization of tanks. Device for pumping oil from the side gearboxes tank containing maclatchie pumps, piping and oil tank, characterized in that it is provided with additional the om and main entrances malooschutimoy pumps, and the electrical circuit of the drive is enabled the timer associated with the gauge tachometer engine tank.
FIELD: mechanical engineering; vertical gear reducers.
SUBSTANCE: proposed vertical gear reducer has housing 1, three stages assembled from cylindrical gear wheels 3, 5, 7 which are rigidly connected with shafts mounted rotatably in bearings 9-12 in housing. Lubricating fluid 13 is located in lower part of housing. Third-stage wheel 7 is partially immersed in lubricating fluid. Fitted on shaft of second-stage wheel 5 is washer 15 which rotates together with pinion stem 6 performing axial and angular motion. End faces 16 and 17 of gear wheels 3 and 7 of first and third stages directed towards second-stage wheel 5 are located in one plane. Washer 15 is pressed to end faces of gear wheels 16 and 17.
EFFECT: enhanced reliability due to reliable delivery of lubricant to teeth of wheels of higher stage.
