Abstract
The utility model relates to a mechanical drive device used for a damper test bench of a locomotive, which comprises a bearing base (1), a bearing (2), an eccentric crank shaft (3), a transmission connecting link, a linear bearing (5), slide blocks (6) and a belt pulley (7). The eccentric crank shaft (3) can be rotationally supported on the bearing base (1) through the bearing (2); the belt pulley (7) is fixedly mounted on the eccentric crank shaft (3); the transmission connecting link comprises a transverse connecting link (4-1) and a longitudinal connecting link (4-2); one end of the transverse connecting link (4-1) is articulated with the eccentric crank shaft (3), and the other end thereof is articulated with the longitudinal connecting link (4-2); the two ends of the longitudinal connecting link (4-2) are connected with the slide blocks (6) respectively; and the slide blocks (6) can be movably supported on the linear bearing (5). The mechanical drive device is mainly utilized on the damper test bench of the locomotive, and converts the rotation motion of a motor into linear motion, therefore, the utility model improves the transmission accuracy and the work efficiency, and has the advantages of stable motion, low noises and long service life.
Description
Technical field
The utility model relates to a kind of locomotive damper test stand mechanical actuation device, mainly is used on the rolling stock damper test stand, makes rotatablely moving of motor be converted into rectilinear motion.
Background technology
Existing locomotive damper test stand adopts crank-linkage type slide block type mechanical actuation device.Crank-linkage type slide block type drive unit is to adopt the eccentric free wheel drive link to drive slide block to carry out sliding straight motion in dovetail groove, this mechanism exists eccentric precision, motion homogeneity not high, noise is big, friction force is big, the energy consumption height, complex structure, serviceable life is low, defectives such as assembling and inconvenient maintenance.
Summary of the invention
The purpose of this utility model provides a kind of transmission accuracy height, mechanical damper testing table mechanical actuation device that noise is low.
The technical scheme that realizes above-mentioned purpose is: a kind of locomotive damper test stand mechanical actuation device, form by bearing seat, bearing, eccentric crankshaft, kinematic link, linear bearing, sliding shoe and belt pulley, eccentric crankshaft can be rotated to support on the bearing seat by bearing, belt pulley is fixedly mounted on the eccentric crankshaft, kinematic link is made up of transverse link and longitudinal rod, one end and the eccentric crankshaft of transverse link are hinged, the other end and longitudinal rod are hinged, the two ends of longitudinal rod sliding shoe respectively connect, and sliding shoe is bearing on the linear bearing movably.
After adopting technique scheme, solve the defective of transmission test bench by eccentric crankshaft linkage assembly and linear bearing combination.The eccentric precision height of eccentric crankshaft makes straight-line precision be controlled at ± 0.01m/s, and operating noise is reduced to 55 decibels by 75 decibels of traditional experiment platform.Work efficiency is greatly improved.
Description of drawings
Fig. 1 looks synoptic diagram for master of the present utility model;
Fig. 2 is the cross-sectional schematic of overlooking of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1, shown in 2, a kind of locomotive damper test stand mechanical actuation device, by bearing seat 1, bearing 2, eccentric crankshaft 3, kinematic link, linear bearing 5, sliding shoe 6 and belt pulley 7 are formed, eccentric crankshaft 3 can be rotated to support on the bearing seat 1 by bearing 2, belt pulley 7 is fixedly mounted on the eccentric crankshaft 3, kinematic link is made up of transverse link 4-1 and longitudinal rod 4-2, an end and the eccentric crankshaft 3 of transverse link 4-1 are hinged, the other end and longitudinal rod 4-2 are hinged, the two ends of longitudinal rod 4-2 sliding shoe 6 respectively connect, and sliding shoe 6 is bearing on the linear bearing 5 movably.Bearing 2 is a ball bearing.Eccentric crankshaft 3 adopts grinding, and the eccentric precision of eccentric crankshaft is controlled at ± 0.03mm after the process grinding, makes straight-line precision be controlled at ± 0.01m/s.
Principle of work of the present utility model following (as shown in Figure 2): electrical motor gearshift mechanism drives eccentric crankshaft 3 by belt pulley 7 and rotates, and eccentric crankshaft 3 drives kinematic link drive sliding shoe 6 and carry out rectilinear motion on linear bearing 5.
