Abstract
The invention provides an automatic lubricating device of a vertical speed reducer, which aims at solving the problem that a gear pump arranged at the bottom part of an oil pool cannot normally work due to that the gear pump usually works in a unidirectional manner but a low-speed large gear rotates in a bidirectional manner. The key points of the automatic lubricating device are as follows: a forward gear and an intermediate gear which are meshed with each other are articulated on the long end of an L-shaped connecting plate, and a reverse gear is articulated on the short end of the L-shaped connecting plate; the intermediate gear, a driving gear of the gear pump and the reverse gear are sequentially meshed; and the corner of the L-shaped connecting plate is a left-right swinging shaft of the L-shaped connecting plate. The automatic lubricating device is used for automatic lubrication of a bidirectional rotary high-position transmission part of the vertical speed reducer.
Description
Technical field
The present invention relates to a kind of automatic lubricator that is applied to the high-order driving parts of the two-way rotation of vertical speed reducer in fields such as metallurgy, electric power, coal, cement, building materials, chemical industry.
Background technique
Splash lubrication is a kind of of retarder lubricating system, but for the retarder of vertical transmission, because its specific structural requirement, during splash lubrication, lubricant oil is difficult to be sent to high-order driving parts place away from oil sump, causes the lubrication circumstances of this place's driving parts to degenerate.
For improving high-order lubrication circumstances away from the oil sump driving parts, the common method that adopts liquid level height in the increase oil sump makes in the most of immersion of the transmission part oil, increases but the thing followed is a churning loss; Simultaneously, the sealing position of lower end output shaft is immersed fully in the oil and also can be quickened the oil sealing premature failure, causes leakage of oil.Therefore, adopting high oil level lubricating system is a kind of unreasonable and helpless mode.
The full depth tooth wheel pump that utilizes the oil sump bottom to install, provide driving force by the slow speed turbine stage gearwheel for it, by auxiliary pressure lubrication mode, improve high-order lubrication circumstances away from oil sump place driving parts, but gear pump is generally one-way only operation, and the two-way rotation of slow speed turbine stage gearwheel, the ratchet pump can't proper functioning.As add motor and provide driving force for it, make then that cost increases, energy waste, also waste energy during work; Increasing by cover motor, a gear pump simultaneously also can increase the complexity and the unreliability of control system.
Summary of the invention
For overcoming the deficiency of prior art, the object of the present invention is to provide a kind ofly provides a kind of lubricating fitting away from the driving parts at oil sump place for a vertical speed reducer high position.
The object of the present invention is achieved like this: in vertical speed reducer oil sump bottom the ratchet pump is installed, it is characterized in that: a hinged forward gear and an intermediate gear on the long end of L shaped joining plate, forward gear and intermediate gear engagement, a hinged reverse gear on the short end of L shaped joining plate, the actuation gear and the reverse gear of intermediate gear, gear pump mesh successively, the turning of L shaped joining plate is the axle of vacillating now to the left, now to the right of L shaped joining plate, when L shaped joining plate is vacillated now to the left, now to the right, forward and reverse gear mesh with vertical speed reducer slow speed turbine stage gearwheel respectively.
Working procedure is: (the long end of establishing L shaped joining plate is in the left side) is when the slow speed turbine stage gearwheel is rotated counterclockwise, the forward gear meshing flank of tooth that is engaged with can be subjected to a power F, this power forms a moment on joining plate, make it around the right pendulum of axle, guarantee the engagement of forward gear and slow speed turbine stage gearwheel, reverse gear separates with the slow speed turbine stage gearwheel.The forward gear turns clockwise, and by intermediate gear, then gear pump driven gear and gear pump turn clockwise; When the slow speed turbine stage gearwheel turns clockwise, the forward gear can be subjected to a power F ' opposite with power F with the flank of tooth of slow speed turbine stage gearwheel engagement, and this power forms moment on jointing plate, makes it around axle left side pendulum, forward gear and slow speed turbine stage gearwheel break away from, and reverse gear then meshes with the slow speed turbine stage gearwheel.At this moment, reverse gear is rotated counterclockwise, and then gear pump driven gear and gear pump turn clockwise.This shows, can guarantee that no matter retarder is clockwise when working or is rotated counterclockwise, and can both guarantee the normal lubricated of transmission part.
Compared with prior art, the invention has the beneficial effects as follows:
1, at vertical type speed reducer (change gear) bottom oil sump place ratchet pump and lubricating fitting are installed, volume is little, compact structure, be easy to realize, and cost is lower.
2, provide power by the slow speed turbine stage gearwheel and do not need additionally to provide, but energy saving.
3, between gear pump and slow speed turbine stage gearwheel, several gears and joining plate are set, make the slow speed turbine stage gearwheel no matter just change still counter-rotating, common ratchet pump can be worked under the two-way rotation condition of retarder, guarantee the lubricated of vertical speed reducer transmission part.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Fig. 1 is the schematic representation that the present invention is installed in vertical speed reducer.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the schematic representation of the another kind of state of Fig. 2.
Embodiment
Referring to Fig. 1, in vertical speed reducer oil sump bottom the ratchet pump is installed, specifically be (referring to Fig. 2): a hinged forward gear 2 and an intermediate gear 3 on the long end of L shaped joining plate 7, forward gear and intermediate gear engagement, a hinged reverse gear 6 on the short end of L shaped joining plate 7, the actuation gear 4 of intermediate gear 3, gear pump 5 and reverse gear 6 mesh successively, the turning of L shaped joining plate is the axle of vacillating now to the left, now to the right of L shaped joining plate, when L shaped joining plate is vacillated now to the left, now to the right, forward and reverse gear respectively with 1 engagement of vertical speed reducer slow speed turbine stage gearwheel.
Referring to Fig. 2, working procedure is: (the long end of establishing L shaped joining plate is in the left side) is when the slow speed turbine stage gearwheel is rotated counterclockwise, the forward gear meshing flank of tooth that is engaged with can be subjected to a power F, this power forms a moment on joining plate, make it around the right pendulum of axle, guarantee the engagement of forward gear and slow speed turbine stage gearwheel, reverse gear separates with the slow speed turbine stage gearwheel.The forward gear turns clockwise, and by intermediate gear, then gear pump driven gear and gear pump turn clockwise; Referring to Fig. 3, when the slow speed turbine stage gearwheel turns clockwise, the forward gear can be subjected to a power F ' opposite with power F with the flank of tooth of slow speed turbine stage gearwheel engagement, this power forms moment on jointing plate, make it around axle left side pendulum, forward gear and slow speed turbine stage gearwheel break away from, and reverse gear then meshes with the slow speed turbine stage gearwheel.At this moment, reverse gear is rotated counterclockwise, and then gear pump driven gear and gear pump turn clockwise.Thus, can guarantee that no matter retarder is clockwise when working or is rotated counterclockwise, and can both guarantee the normal lubricated of transmission part.
The long end of L shaped joining plate also can be in the left side.Above-mentioned working procedure is opposite.
