Abstract
The invention discloses a transmission mechanism for a rotary encoder for the detection of the mileage of a small rail car, and the transmission mechanism comprises the rotary encoder, a shaft coupler of the rotary encoder, two opposite shaft frame plates, synchronous pulleys supported by two end shafts at the bottoms of the shaft frame plates, closed loop tooth-shaped synchronous belts which are engaged with the synchronous pulleys, a central synchronous pulley, and a shaft seat plate of the central synchronous pulley. The shafts of the synchronous pulleys at two ends of the bottoms of the shaft frame plates are respectively provided with the same transmission belt pulleys in a fixed manner. The closed loop tooth-shaped synchronous belts engaged with the two transmission belt pulleys are engaged with the central synchronous pulley. The rotary encoder in transmission connection with the central synchronous pulley and the two transmission belt pulleys are respectively provided with two closed loop tooth-shaped synchronous belts. Therefore, the transmission mechanism can prevent the loosening and deformation of the closed loop tooth-shaped synchronous belts for sliding prevention from causing interference with the rotary encoder. The transmission mechanism is simple in structure, and facilitates the improvement of mileage measurement and repeated positioning precision.
Description
Technical field
The invention belongs to track geometry measuring device, more particularly to a kind of transmission of small rail car mileage detection rotary encoder
Mechanism.
Background technology
Track detecting dolly be a kind of detection static track mileage and height, level, distortion, rail to etc. track irregularity join
Several portable tools.
Rotary encoder is that the little car kilometer of track detecting measures critical piece, usual rotary encoder and track detecting dolly
The wheel shaft of the front vehicle wheel or single-wheel side wheel of two-wheel side is connected by shaft coupling transmission, in practice it has proved that the mileage of the transmission mechanism is surveyed
Amount error and repetitive positioning accuracy are than relatively low, it is impossible to meet the requirement of railway mileage measurement accuracy.
The application for a patent for invention ' snow tire of track detecting dolly ' of publication number 104553602A discloses following technology
Scheme：Corresponding its bottom of two pedestals plate in position is respectively arranged at two ends with the synchronous pulley of axle support, and two synchronous pulleys are provided with and which
The closed loop tooth form synchronous belt being meshed, the rubber outer surface of closed loop tooth form synchronous belt are engaged with raceway surface, two pedestal plates
Top is provided with the top board of supporting trolley main body, and the two pedestals plate is respectively equipped with the axle bed for supporting mid-ambles belt wheel wheel shaft two ends
Plate, the upper portion of the closed loop tooth form synchronous belt between mid-ambles belt wheel and two synchronous pulleys are meshed, the mid-ambles
The side axle bed plate of belt wheel is fixed with encoder, is provided with shaft coupling between encoder axle and mid-ambles belt wheel wheel shaft.
Above-mentioned technical proposal not only thoroughly overcomes the technical problem of steel wheel-slip, while also preferably resolving rotation
The wheel shaft for turning encoder with the front vehicle wheel or single-wheel side wheel of track detecting dolly two-wheel side is connected presence by shaft coupling transmission
Mileage measure error and repetitive positioning accuracy than relatively low technical problem.
But, in above-mentioned technical proposal, two synchronous pulleys and mid-ambles belt wheel share same closed loop toothed synchronous with can
Can there is the interference produced to rotary encoder because of the loosening of closed loop tooth form synchronous belt, deformation etc..
The content of the invention
The present invention is to solve two synchronous pulleys and mid-ambles belt wheel and share same closed loop tooth form synchronous belt to go out
Now because the loosening of closed loop tooth form synchronous belt, deformation etc. produce the technical problem of interference to rotary encoder, and it is little to disclose a kind of track
Car kilometer detects the transmission mechanism of rotary encoder.
The present invention takes technical scheme below for achieving the above object：A kind of small rail car mileage detection rotary encoder
Transmission mechanism, supports including rotary encoder and its shaft coupling, the corresponding two pedestals plate in position, two pedestal plate bottom two end axles
Synchronous pulley and meshed closed loop tooth form synchronous belt, mid-ambles belt wheel and its axle bed plate, are characterized in that, two pedestal
Synchronous pulley its wheel shaft at plate bottom two ends is respectively fixed with identical drive pulley, is engaged in the closed loop profile of tooth of two drive pulleys
Drive coordination band is meshed with mid-ambles belt wheel.
The present invention may also take on following technical measures：
Shaft coupling between the wheel shaft of mid-ambles belt wheel and the power input shaft of rotary encoder is flexible coupling
Device.
The feather edge of the two pedestals plate is interval with the permanent magnet corresponding to track.
Advantages and advantages of the invention are：The transmission mechanism of this rotary encoder is on the basis of snow tire
Two drive pulleys with two synchronous pulley synchronous axial systems in snow tire are increased, two drive pulleys are same by the transmission of closed loop profile of tooth
Step band is connected with mid-ambles belt wheel transmission, it is seen that the rotary encoder and two synchronous pulleys point of mid-ambles belt wheel transmission connection
If two closed loop tooth form synchronous belts, therefore the closed loop tooth form synchronous belt generation loosening of anti-skidding effect, deformation generation can be avoided right
The interference of rotary encoder.Meanwhile, two synchronous pulleys increased range finding stability and the frictional force with rail, when wherein one wheel
When skidding, vacantly dallying, a wheel to contact with rail rail level, and can provide enough frictional force drive mid-ambles bands in addition
Move with mid-ambles belt wheel, make detection rotary encoder detection signal be exported according to actual conditions.The present invention has structure letter
Outstanding advantages that are single, being conducive to the measurement of raising mileage and repetitive positioning accuracy.
