Abstract
The utility model relates to a test run bench consisting of a dynamometer, a coupler and a base, wherein the dynamometer and the coupler are arranged on the base; the dynamometer is connected with the coupler; and the coupler is connected with an engine. The test bench is characterized by also being provided with a cold dragging device, and the cold dragging device is arranged on the base and connected with the dynamometer. The benefits are as follows: as an external variable-frequency motor is adopted, engine oil is injected in an engine oil passage when the engine is not started, the oil pressure of the engine oil passage is established already when the engine is in low rotation speed, and the problems that the early abrasion of a cylinder jacket during engine test and the like are solved.
Description
Technical field
The utility model relates to the test run stand, relates in particular to a kind of test run stand with cold dragging device.
Background technology
The engine run stand possesses the engine torque of measurement, rotating speed, oil consumption, the isoparametric function of discharging, often need expose engine various obstacles that may occur and the various parameters of collecting the engine runnability by engine run.At present, the engine run stand has become the real and the most reliable means of Engine Block Test that solve.In the engine test field, the test run stand generally is to start by engine self starter, again with in the machine oil injection engine oil duct, but does like this behind the engine combustion, just do not have oil pressure in a period of time that engine brings into operation, make the problem of motion width of cloth premature wears such as cylinder sleeve of engine easily.
Summary of the invention
The purpose of this utility model is at top described defective, provides a kind of and can solve the test run stand with cold dragging device that engine run produces cylinder sleeve premature wear problem.
The purpose of this utility model is achieved by the following technical programs.
A kind of test run stand is made of dynamometer, shaft coupling and base, and dynamometer and shaft coupling are installed on the base, dynamometer is connected with shaft coupling, and shaft coupling is connected with engine, it is characterized in that, cold dragging device also is installed, and described cold rest device is installed on the base, is connected with dynamometer.
Described cold dragging device is made of variable-frequency motor, deceleration belt, connection bearing, pneumatic jaw clutch, variable-frequency motor be connected bearing and be fixedly mounted on the base, pneumatic jaw clutch is installed in and connects the bearing upper end, is connected with variable-frequency motor by the deceleration belt.
The rotating speed of described variable-frequency motor and time can revise by programming.
During use, by the rotation of deceleration belt drives dynamometer, dynamometer drives engine by shaft coupling, behind engine start, by pneumatic jaw clutch cold dragging device and engine is separated again by variable-frequency motor.
The invention has the beneficial effects as follows: owing to adopted outside variable-frequency motor, when also not starting, just machine oil has been injected by engine the engine oil duct, make and when the slow-speed of revolution, just the oil pressure of engine oil duct is set up, solved engine run and produced premature wear problems such as cylinder sleeve.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Among the figure, 1 dynamometer, 2 shaft couplings, 3 bases, 4 cold dragging devices, 5 variable-frequency motors, 6 deceleration belts, 7 connect bearing, 8 pneumatic jaw clutches.
Embodiment
A kind of test run stand is made of dynamometer 1, shaft coupling 2 and base 3, and dynamometer 1 is installed on the base 3 with shaft coupling 2, and dynamometer 1 is connected with shaft coupling 2, and shaft coupling 2 is connected with engine, and cold rest device 4 is installed on the base 3, is connected with dynamometer 1.
Described cold dragging device 4 is made of variable-frequency motor 5, deceleration belt 6, connection bearing 7, pneumatic jaw clutch 8, variable-frequency motor 5 be connected bearing 7 and be fixedly mounted on the base 3, pneumatic jaw clutch 8 is installed in and connects bearing 7 upper ends, is connected with variable-frequency motor 5 by deceleration belt 6.
The rotating speed of described variable-frequency motor 5 and time can revise by programming.
During use, drive dynamometer 1 rotation by variable-frequency motor 5 by deceleration belt 6, dynamometer 1 drives engine by shaft coupling 2, behind engine start, by pneumatic jaw clutch 8 cold dragging device 4 is separated with engine again.
