Abstract
The utility model relates to a trolley driving device with a pressure spring swinging bracket, which comprises a driving gear fixed on a driving motor and a driving rack bar welded on a trolley bracket. The utility model is characterized in that the utility model is composed of the driving motor with a speed reducer, a swinging bracket and an adjusting and pressing mechanism, wherein the driving motor is installed on the swinging bracket; the motor and the driving rack bar on the trolley bracket are connected by a driving mechanism; the swinging bracket is connected with the adjusting and pressing mechanism. The utility model has the advantages that the swinging bracket with a pressure spring can adjust the deformation of the rack bar and errors in installation and manufacture and can ensure the engaging accuracy of the driving gear and the driving rack bar of a trolley; the utility model can drive the trolley to go in and go out of a trolley stove accurately and always keep the trolley to run along a track smoothly and stop accurately.
Description
Technical field:
The utility model belongs to a kind of chassis drive unit in car-type heating or the heat-treatment furnace.Specially refer to a kind of chassis drive unit with the stage clip swinging mounting.
Background technology:
China uses a lot of car type furnaces at workpiece heating and heat treatment industry at present, and chassis drives most the employing, stirs the driving tooth bar that is welded on the chassis support by the driven wheel that is fixed on the drive motors, makes chassis do moving of turnover stove.This class chassis drives and has a lot of problems: because the chassis temperature is higher; the driving tooth bar that is welded on the chassis support often can be out of shape to some extent; error and long-time use back wearing and tearing that tooth bar is made than the Chang'an dress; all can't guarantee the accurate engagement of driving gear wheel and rack; thereby may cause chassis operation shake; the location of chassis turnover stove is inaccurate, can not transmit chassis even and drive needed power, and chassis can't move.The ordinary production rhythm that this has just influenced car type furnace reduces output, and has increased the cost of repair and maintenance.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of chassis drive unit with the stage clip swinging mounting is provided.This device is to improving the behaviour in service of car type furnace, and provide the service life of the positioning accuracy of raising chassis and prolongation mechanism may.
The technical solution of the utility model is: a kind of chassis drive unit with the stage clip swinging mounting, comprise driven wheel that is fixed on the drive motors and the driving tooth bar that is welded on the chassis support, it is characterized in that: drive motors, swinging mounting and adjustment hold-down mechanism by the band reductor are formed, drive motors is installed on the swinging mounting, is connected by transmission mechanism between the driving tooth bar on motor and the chassis support; Swinging mounting is connected with the adjustment hold-down mechanism.
One end of described swinging mounting links to each other with fixed frame by a rotating shaft, and the other end is installed a cover and adjusted hold-down mechanism, and this is adjusted hold-down mechanism and is connected with fixed frame.
Described transmission mechanism is the two poles of the earth transmission mechanism, and this mechanism forms by being connected drive motors output shaft upper transfer gear and driven wheel, and travelling gear is meshed with driven wheel, and travelling gear and driven wheel are installed on the swinging mounting.
Described adjustment hold-down mechanism is made up of the screw rod and the thrust bearing of a band stage clip, is connected with nut on the upper end of screw rod and the fixed frame, and thrust bearing is equipped with in the lower end of screw rod.
The utility model has the advantages that: the stage clip swinging mounting that has can be regulated the tooth bar distortion and the error of making is installed, guarantee the accuracy of mesh of the driving tooth bar of driven wheel and chassis, can drive chassis turnover car type furnace exactly, remain chassis along the track even running, off-position is accurate.
Description of drawings:
Fig. 1 is a schematic diagram of the present utility model
Fig. 2 is the A-A profile of Fig. 1
The specific embodiment:
As shown in the figure: moving of chassis, stir the driving tooth bar (6) that is contained on the chassis support by drive motors (1) by two-stage drive driven gear (3), make chassis do moving of turnover stove along track.The motor (1) of band reductor is installed on the swinging mounting (4), a travelling gear of its output shaft band (2), travelling gear comes transferring power by another driven wheel (3), these gears all are installed on the swinging mounting (4), as long as guarantee the location dimension of these two installing holes and the machining accuracy of gear, just can be relatively easy to control these two gear meshing precision.Increased output torque by such two-stage transmission.One end of swinging mounting (4) links to each other with fixed frame (7) by a rotating shaft (8), and swinging mounting (4) can rotate around axle (8), and other end band one cover is adjusted hold-down mechanism.Adjusting hold-down mechanism is made up of the screw rod (10) and the thrust bearing (5) of a band stage clip (9), the upper end of screw rod (10) is gone up with fixed frame (7) and is connected with nut (11) (12), thrust bearing (5) is equipped with in the lower end of screw rod (10), like this by regulating the pretightning force of stage clip, because but the effect swinging mounting upper and lower displacement of stage clip guarantees that the driven wheel (3) and the driving tooth bar (6) of chassis mesh all the time.Owing to adopted such structure, whether no matter whether the chassis tooth bar is out of shape, wear and tear to guarantee the accuracy of mesh of driving gear wheel and rack, remains chassis along the track even running, and off-position is accurate.
Claims (4)
