Description
Technical Field
The invention relates to the technical field of measuring devices, in particular to a continuous displacement measuring device of a large-stroke sliding component of a synchronous automatic clutch.
Background
The synchronous automatic clutch is a high-power-density and high-reliability tooth clutch which is automatically engaged and disengaged by means of the change of the rotation speeds of an input end and an output end, and is widely applied to the power transmission fields of ships, metallurgy, chemical industry, power generation and the like. The synchronous automatic clutch mainly comprises an input assembly, a sliding assembly and an output assembly, and the synchronous automatic clutch is in an engaged or disengaged state, which is a key operation parameter in practical application.
The synchronous automatic clutch may be judged to be in an engaged state or a disengaged state by monitoring the axial position of the slip assembly. Currently, a measurement device for monitoring the position of a clutch slip assembly generally employs a method of providing two radially arranged eddy current proximity switches at the engaged and disengaged positions of the clutch slip assembly. When the clutch slip assembly is in the engagement position, a proximity switch of the engagement position outputs an effective signal; when the clutch slip assembly is in a disengaged position, a proximity switch in the disengaged position outputs a valid signal; when the clutch sliding assembly is in an engaged and disengaged intermediate position, no effective signal is output by the two proximity switches, and the specific position and the movement state of the clutch sliding assembly cannot be determined; when the clutch fails to engage or disengage, accurate position data of the clutch slip assembly cannot be obtained, and accurate diagnosis of the failure can not be made.
As shown in fig. 1, the basic structure of the synchronous automatic clutch in the prior art is composed of a clutch output assembly 100, a clutch slip assembly 200 and a clutch input assembly 300, and the axial movement of the clutch slip assembly 200 realizes the engagement and disengagement of the synchronous automatic clutch. The position of the clutch slip assembly 200 is typically monitored by a radially disposed proximity switch, and when the clutch slip assembly 200 is moved to the engaged position, the measuring ring 201 triggers the engaged position proximity switch 500 to output a signal representative of synchronous automatic clutch engagement, as shown in FIG. 2. When the clutch slip assembly 200 is moved to the disengaged position, the measuring ring 201 triggers the disengaged position proximity switch 400 to output a signal representing the synchronized automatic clutch disengagement, as shown in FIG. 1. The monitoring method has the defects that only two states of engagement or disengagement of the clutch slip assembly 200 can be displayed, the state in the middle of the two positions cannot be monitored, when the synchronous automatic clutch has engagement or disengagement faults, the position of the clutch slip assembly 200 cannot be judged, data cannot be provided for fault cause analysis, and the method is only suitable for the condition that the engagement/disengagement stroke of the slip assembly is short.
To solve the problem that the continuous displacement of the slip assembly cannot be monitored, an improved measurement method in the prior art is shown in fig. 3, and the axial displacement of the measurement ring 201 of the clutch slip assembly 200 is monitored by using the eddy current displacement sensors which are axially arranged, so that accurate continuous displacement measurement can be realized, and the displacement measurement range of the clutch slip assembly 200 can be improved by arranging two eddy current displacement sensors, namely, the eddy current displacement sensor 410 at the 1 disengaging position and the eddy current displacement sensor 510 at the 1 engaging position, in combination, as shown in fig. 3 and 4. However, even if two eddy current displacement sensors are combined, the method is only suitable for the condition that the engagement/disengagement stroke of the clutch slip assembly 200 is short, the diameter size of the eddy current displacement sensors is greatly increased along with the increase of the measured displacement stroke, and domestic and foreign data show that the displacement measurement range of the eddy current sensors with the diameter of 8mm is 2mm, and the displacement measurement range of the eddy current sensors with the diameter of 60mm is only 50mm. When the synchronous automatic clutch size is large due to a large increase in the transmitted torque, such as a combined combustion-steam cycle generator set clutch, a ship propeller shaft clutch, the engagement/disengagement stroke of the large stroke slip assembly 210 is around 80-130mm, and even larger as shown in fig. 5, it has a large stroke clutch output assembly 110, a large stroke slip assembly 210, and a large stroke clutch input assembly 310. As shown in fig. 6, in order to match the measurement space of the eddy current displacement sensor, the large-range eddy current displacement sensor 411 at the disengaged position and the large-range eddy current displacement sensor 511 at the engaged position are selected, or in order to match the measurement space of the large-range eddy current displacement sensor, the diameter of the large-range measuring ring 211 is required to be made large, resulting in waste of space and material. The measurement method using an axially arranged eddy current displacement sensor is therefore not suitable for large stroke slip assemblies. And because the operation environment of the synchronous automatic clutch is a splash oil pollution environment, the stroke of the sliding component cannot be measured by adopting an ultrasonic sensor.

As shown in fig. 9 to 12, taking an example that a plane formed by an axis of the spindle 640 and an axis of the fork 660 is perpendicular to the axis of rotation 710 of the synchronous automatic clutch when the synchronous automatic clutch is disengaged, the angle sensor 680 in fig. 12 measures the feedback angle as α, and the angle α is a constant value, which is determined by an initial installation state of the angle sensor 680; after the synchronous automatic clutch starts to engage, the large-stroke measuring ring 211 moves to the engaged position, the angle sensor 680 measures the feedback angle β, the angle β is a variable, the distance L between the axis of the spindle 640 and the axis of the fork 660 is determined by the position of the large-stroke measuring ring 211, the distance L is a constant value, and the real-time displacement S of the large-stroke slip assembly 210 is determined by the structure of the displacement measuring device, and can be calculated according to the following formula:

as shown in fig. 13, to lubricate the spindle 640, to avoid the abrasion seriously affecting the service life, in the present invention, it further includes:
an oil inlet pipe 670 having one end communicating with the annular chamber 621 and the other end communicating with an oil inlet joint outside the flange plate 610;
the lubricating oil in the oil inlet pipe 670 lubricates the spindle 640 through the annular cavity 621, specifically:
the oil inlet pipe 670 is connected between the flange plate 610 and the shaft sleeve 620, lubricating oil is led into the oil inlet pipe 670 through an oil inlet joint outside the flange plate 610, two ends of the matching position of the shaft sleeve 620 and the mandrel 640 are of sealing structures, the two ends are respectively sealed through two O-shaped rings, the middle part of the sealing structures is a ring cavity 621 with the radius difference of 3mm, and the lubricating oil in the oil inlet pipe 670 can enter the ring cavity 621 to lubricate the mandrel 640 so as to avoid abrasion of the mandrel 640, and the service life of the sealing structures is prolonged.
In the case of a high power (more than 90 MW) generator set synchronous automatic clutch application, the linear speed of the contact position of the fork 660 and the large-stroke measuring ring 211 can reach 150m/s, and in order to ensure that the fork 660 is not worn, a sufficient amount of lubricating oil is supplied to the friction surface between the fork 660 and the large-stroke measuring ring 211. In order to solve the lubrication technical problem of the contact position of the fork 660 and the large-stroke measuring ring 211, as shown in fig. 13-15, in the present invention, a first radial hole 641, a second radial hole 643 and a first axial hole 642 which are mutually communicated are formed on the mandrel 640, wherein the first radial hole 641 is formed near the middle, and the second radial hole 643 is formed near the bottom;
a long hole 651 is formed in the connecting rod 650;
a second radial hole 662 and a second axial hole 663 which are mutually communicated are formed in the shifting fork 660, and a ring groove 661 communicated with the second radial hole 662 is formed in the rotating shaft of the shifting fork 660;
both ends of the long hole 651 are respectively communicated with the first radial hole two 643 and the annular groove 661.
In the present invention, the oil distributing hole and the friction surface oil spraying hole 666 are formed in the fork 660, the lubricating oil is sprayed out from the oil distributing hole and the friction surface oil spraying hole 666 to lubricate the fork 660 and the friction surface between the fork 660 and the large-stroke measuring ring 211, wherein the oil distributing hole in the fork 660 can be 1 first-stage oil distributing hole 664, 2 second-stage oil distributing holes 667 and 6 third-stage oil distributing holes 665, and the friction surface oil spraying hole 666 can be 6.
In the present invention, the blocking cover 630 has a cavity 631 therein;
since the annular cavity 621 with the radius difference of 3mm formed between the shaft sleeve 620 and the mandrel 640 is supplied with lubricating oil with a certain pressure, even if two O-rings are adopted for sealing, after long-time operation, lubricating oil leaks into the cavity 631 in the blanking cover 630 from the sealing positions of the O-rings, after the lubricating oil is fully accumulated in the cavity 631, a certain pressure is established, and the lubricating oil leaks out from the installation gap between the mandrel 640 and the blanking cover 630 and the installation gap between the blanking cover 630 and the flange plate 610, so that the lubricating oil leaks out of the housing 700 of the synchronous automatic clutch, and the environment is polluted. In order to solve the problem, as shown in fig. 16, the present invention adopts a technical scheme that an oil drain hole 622 is formed in a shaft sleeve 620, so as to drain the lubricating oil stored in a cavity 631 in time to the inside of a housing 700 of the synchronous automatic clutch, thereby avoiding environmental pollution caused by leakage of the lubricating oil.
