Sprocket shaft group testing table
Technical field
The present invention relates to a kind of test unit, relate to specifically a kind of no-load test platform.
Background technology
In mining machinery, various scraper conveyors and elevating conveyor are all to rely on the rotation of sprocket shaft group to drive scraper chain to carry out work, in order to guarantee the overall quality of sprocket shaft group, generally after assembling, all to carry out test run experiment, the test of the sprocket shaft group of scraper conveyor and elevating conveyor is subject to the restriction of connected mode, existing testing table can only be tested the drive sprocket axle group that has key to connect, and the passive sprocket shaft group of transfer conveyor tail is because not having spline or flat key to be used for transmitting torque, therefore can not test separately.
Summary of the invention
The object of this invention is to provide a kind of sprocket shaft group testing table, it can be tested the sprocket shaft group that cannot connect input torque by key.
To achieve these goals, technical solution of the present invention is: a kind of sprocket shaft group testing table, comprise motor, sprocket shaft group driving wheel, motor is by gearing connection chain axle set driving wheel, sprocket shaft group driving wheel is removably connected with clamping plate, clamping plate are circular, the internal diameter of sprocket shaft group driving wheel is greater than the external diameter at sprocket shaft group axle journal place, the internal diameter of clamping plate equates with the external diameter at sprocket shaft group axle journal place, motor and gearing are all fixed on base, on base, be also provided with two for the holder of fixed chain wheels axle group, clamping plate are located between two holders.
Sprocket shaft group testing table of the present invention, wherein, the output shaft of described motor is provided with small belt pulley, and the input end of transmission shaft is provided with big belt pulley, between small belt pulley and big belt pulley, passes through belt gear.
Sprocket shaft group testing table of the present invention, wherein, described sprocket shaft group driving wheel is large profile of tooth sprocket wheel, the output terminal of described transmission shaft is provided with little profile of tooth sprocket wheel, between large profile of tooth sprocket wheel and little profile of tooth sprocket wheel, is provided with silent chain.
Sprocket shaft group testing table of the present invention, wherein, described clamping plate are connected with fixed head by the stud bolt of several circumferential array, and fixed head is circular, and fixed head is located between two holders.
Sprocket shaft group testing table of the present invention, wherein, described holder comprises V-arrangement axle bed and pressing plate, V-arrangement axle bed is connected with pressing plate by bolt.
Sprocket shaft group testing table of the present invention, wherein, described gearing is reduction gear.
Adopt after such scheme, sprocket shaft group testing table of the present invention is owing to comprising motor, transmission shaft and sprocket shaft group driving wheel, sprocket shaft group driving wheel can fix by the axle journal place of clamping plate and sprocket shaft group, therefore in the situation that cannot connecting input torque by key, can to sprocket shaft group, test by sprocket shaft group driving wheel input torque.
In addition, because clamping plate are connected with fixed head, fixed head is for being enclosed within the lower end-journal place of sprocket shaft group rotating part, therefore when the axle journal outside dimension shorter or axle journal of the rotating part of sprocket shaft group does not mate with clamping plate, can the rotating part of sprocket shaft group and driving wheel be fixed by fixed head, by driving wheel input torque, sprocket shaft group is tested, can be carried out unloaded test run to all sprocket shaft groups.

Embodiment
As Fig. 1, shown in 2, sprocket shaft group testing table of the present invention comprises motor 1, transmission shaft 2, the output shaft of motor 1 is provided with small belt pulley 11, transmission shaft 2 is located on bearing seat 21, the input end of transmission shaft 2 is provided with big belt pulley 22, output terminal is provided with little profile of tooth sprocket wheel 23, between small belt pulley 11 and big belt pulley 22, pass through belt 3 transmissions, little profile of tooth sprocket wheel 23 connects large profile of tooth sprocket wheel 5 by silent chain 4, large profile of tooth sprocket wheel 5 is the driving wheel of sprocket shaft group, Hafu-type clamping plate 6 are enclosed within the axle journal place, upper end of sprocket shaft group 10, Hafu-type clamping plate 6 are circular, large profile of tooth sprocket wheel 5 is enclosed within sprocket shaft group 10 axle journal places, Hafu-type clamping plate 6 outsides, the internal diameter of Hafu-type clamping plate 6 equates with the external diameter at sprocket shaft group 10 axle journal places, the internal diameter of large profile of tooth sprocket wheel 5 is greater than the external diameter at sprocket shaft group 10 axle journal places, large profile of tooth sprocket wheel 5 is connected with Hafu-type clamping plate 6 by screw, motor 1, bearing seat 21 is all fixed on base 9, on base 9, be also provided with two V-arrangement axle beds 91, each V-arrangement axle bed 91 has been bolted respectively pressing plate 911, the fixed part at sprocket shaft group 10 axial two ends is located at respectively on a V-arrangement axle bed 91, and be bolted by pressing plate 911.
When the axle journal of sprocket shaft group 10 is shorter or the outside dimension of axle journal and the internal diameter of Hafu-type clamping plate 6 when variant, fixed head 7 is set, fixed head 7 is circular, be enclosed within 10 times end-journal places of sprocket shaft group, Hafu-type clamping plate 6 and fixed head 7 are all arranged between two V-arrangement axle beds 91, and connect by the stud bolt 8 of a plurality of circumferential array, stud bolt 8 is through the rotating part of sprocket shaft group 10.
During test, motor 1 rotates, by transmission shaft 2, little profile of tooth sprocket wheel 23, large profile of tooth sprocket wheel 5, drive sprocket shaft group 10 to dally with the working speed close to design, in idle running process, observe the whether leakage of oil of sprocket shaft group, and judge that according to the noise situation in idle running process, temperature rising situation whether sprocket shaft group is qualified.
The above embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that the common engineering technical personnel in this area make technical scheme of the present invention, all should fall in the definite protection domain of claims of the present invention.
