Description

The utility model relates to the field of engineering, in particular to the stands for testing engineering products and can be used for running in, running in and testing gearboxes.
A well-known test bench for gearboxes, consisting of a rigid massive frame, on which the test gearbox is mounted, the input shaft of which is connected through an electric brake to an electric motor. The gear couplings of the gearbox under test are mounted in bearings. An electric motor alternately connected to each of the bearings of the gearbox under test is connected through sensors to a computing device.
During testing, with the engine turned on, the input shaft, on which the electric brake is installed, rotates one of the gear couplings of the technological gearbox. The test gearbox is loaded by applying pressure, for example, to a mechanical or hydraulic device mounted on a test bench.
Gear couplings of a reducer are fixed in bearings. An electric drive alternately connected to each of the bearings of the gearbox under test is connected through magnetic sensors to a computing device that reads information from the sensors, processes it, and provides a diagram of the operating modes of the bearings.
(see RF patent for utility model No. 66045, class G01M 13/02, 2007).
As a result of the analysis of the known stand, it should be noted that the test of bearings by vibration diagnostics allows for a short time to identify existing malfunctions and take measures to eliminate them, while the known stand can significantly reduce the time to obtain information about existing changes in the bearing units and the durability of the tested gearboxes or pumps compared to the time period of their operational tests. However, this stand has a rather limited technological capabilities, as it is intended only for testing gears of the same type.
A known test bench for gearboxes containing the drive installed on the bed, bench and test gearboxes with the same gear ratios, kinematically connected by the output shafts by means of a rigid coupling. The input shafts of the gearboxes are kinematically connected by means of a kinematic system consisting of gears connected by a torsion bar, one of which is connected to the drive. The housing of the bench gear is kinematically connected to the bed with the possibility of angular rotation of the gear housing relative to the common axis by means of a helical gear that closes the frame with the gear housing through the dynamometer.
In the process of operation of the stand by the drive on the tested gearbox, a load is created by the forces of elastic deformations of the torsion bar twisted to a certain angle by turning the housing of the bench gear relative to the bed with a helical gear. The torsion angle of rotation determines the load torque on the gearbox under test. The reaction from this moment is measured by a dynamometer.
(see RF patent for utility model, patent No. 74986, F16H 1/32, 2008) is the closest analogue.
A disadvantage of the known stand is that loading is carried out by twisting the elastic element, and twisting can only be carried out with the shafts stationary, which eliminates the possibility of changing the load parameters during operation of the stand, thereby not providing the possibility of studying transient conditions. A disadvantage of the known design of the stand is also limited functionality due to the inability to adjust the relative position of the tested gearbox, process gearbox, load mechanism
The technical result of this utility model is to expand the technological capabilities of the bench by providing the ability to adjust in a wide range of sizes the relative position of the test gearbox, process gearbox and bench load mechanism.
The specified technical result is ensured by the fact that in the test bench for gearboxes containing the base, the drive of the high-speed shaft of the gearbox under test, the technological gearbox that can be connected to the low-speed shaft of the gearbox under test, as well as the load-measuring device, it is new that the base is made in two mutually perpendicular directions of the grooves, the drive of the high-speed shaft of the gearbox, the technological gearbox with a load-measuring device, and also the gearbox under test Each is mounted on a separate upper plate connected to the lower plate by means of height-adjustable supports, while the lower plates are equipped with clamping screws designed to fix the lower plates on the base after exhibiting the stand assemblies in a predetermined position in the longitudinal, transverse directions, as well as height.
The essence of the utility model is illustrated by graphic materials on which:
- in FIG. 1 - stand for testing gearboxes, side view;
- in FIG. 2 - test bench for gearboxes, top view.
The test bench for gearboxes contains a base 1 on which T-grooves are made (not indicated by the position) located in mutually perpendicular planes.
The stand is equipped with a drive 2, including an electric motor 3, the output shaft of which is kinematically connected to a spindle 4 mounted with the possibility of rotation in the headstock (not indicated by a position), carrying a coupling 5, designed to connect the spindle 4 to the high-speed shaft of the tested gearbox 6, the low-speed shaft of which the clutch 7 and installed in the headstock (not indicated by position) spindle 8 has the ability to connect to the low-speed shaft of the technological gear 9. The high-speed shaft of the technological gear is connected with scarlet load-measuring device 10.
It should be noted, and it is very important that the drive 2, the tested gearbox 6, the technological gearbox 9 with a load-measuring device are installed on the upper plates (11, 12, 13, respectively). The upper plates by means of supports 14 are connected to the lower plates 15, 16, 17.
In the lower plates, holes or grooves are made through which bolts 18 are passed, the heads of which are placed in the grooves of the base 1, and clamping nuts (not marked) are screwed onto the threaded part of the screws. Due to the placement in the grooves, each of the lower plates, and, consequently, the upper plates, has the ability to move in the longitudinal and transverse directions (in two coordinates).
It is also very important that each of the supports 14 is configured to adjust its height. The support structurally adjustable in height can be solved in a variety of known ways, for example, in the form of a movable glass-rod connection, the glass of which is fixed to the upper plate and the rod to the lower one. Holes were made along the height of the glass and the rod (the number of which should be equal to the parametric series of the tested gearboxes) into which a lock (not shown) is inserted when the support is set to a given height. The supports can be structurally solved in the form of two elements (a rod and a sleeve) connected by a helical gear (like jacks). This allows for smooth adjustment of the height of the supports. The presence of height-adjustable supports allows you to adjust the height of each unit of the stand (third coordinate).
All structural components and elements used in the stand, the implementation of which are not described in this application, are known and implement their inherent functions, their specific implementation is not subject to patent protection.
The test bench for gearboxes works as follows.
Before the tests, the plates 11, 12, 13 are installed in a predetermined position along the height, as well as relative to each other in the longitudinal and transverse directions (they exhibit in three coordinates).
For testing, the gearbox to be tested is mounted on the plate 12. On the plate 11, (if they have not been placed in advance), an electric motor 3 and a headstock with a spindle 4 carrying a coupling 5 are placed. Connect the output shaft of the electric motor to the spindle. A technological gearbox 9 with a load-measuring device 10 is installed on the plate 13.
Next, the elements of the stand are docked, for which, by moving the bolts 18 in the grooves of the base and adjusting the supports 14 in height, they provide the necessary position of the spindles 4 and 8 relative to the high-speed and low-speed shafts of the tested gearboxes, after which the shafts of the tested gearbox are connected to the spindles using couplings 5 and 7.
The stand is ready for testing.
For testing, the electric motor is switched on and a regulated cycle of technological tests of the gearbox is carried out, for example, for compliance of its parameters with technical conditions, or gearbox is run-in.
The use of the stand provides testing of a wide range of gearboxes by providing separate regulation of the set position of each unit of the stand in three coordinates.
