Abstract
The utility model discloses a trundle for tracks, which comprises two parallel tracks and a vehicle body, wherein a vehicle shaft is arranged in the vehicle body; the two ends of the vehicle shaft stretching out of the vehicle body are respectively provided with idler wheels through a duplex bearing; the idler wheels are respectively arranged on the two parallel tracks and matched with the parallel tracks in a sliding way; annular steps are arranged on the outer side walls of the idler wheels, the side walls of the annular steps are slope surfaces; and the end part of the vehicle body is fixedly provided with a motor, the motor is connected with the vehicle shaft in a transmission way. The trundle has a simple and reliable structure, the idler wheels are arranged through the duplex bearing, the installation intensity of the idler wheels is enhanced; the idler wheels can be stressed more uniformly, therefore, the service life of the vehicle body is prolonged; furthermore, as the contacting surfaces of the idler wheels and the tracks are designed into slope surfaces, the sliding resistance is reduced, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of small rail car wheel.
Background technology
In field of machining, need to use hoisting crane to come hoisting heavy, hoisting crane is called driving again usually, and driving has two classes substantially: a class is a centralized driving, promptly drives the adhesion wheel on both sides with a motor drives long pass moving axis; Another kind of for drive respectively, be both sides adhesion wheel each with a direct motor drive.
The more employing drg of medium and small crane in bridge type, retarder and motor unit incorporated " three-in-one " type of drive, the ordinary bridge crane of big elevating capacity is for ease of installing and adjusting, and actuating device often adopts universal coupling.
Existing driving roller adopts single shaft to hold installation mostly, causes the unbalance stress between roller and the axletree, and the contact surface of the track of roller mostly is greatly and faces directly, and contact surface is bigger, causes resistance bigger, has influenced work efficiency greatly.
The utility model content
The purpose of this utility model provides a kind of small rail car wheel, adopts duplex bearing that roller is installed, and improve the service life of car body, and the face that roller is contacted with track makes slope into, the resistance when reducing to slide.
The technical solution of the utility model is as follows:
A kind of small rail car wheel, include two parallel tracks and car body, be provided with axletree in the described car body, it is characterized in that: the two ends of described axletree are stretched out from car body respectively and by duplex bearing roller are installed respectively, described roller places on two parallel tracks respectively and the slide parallel with two cooperates, the lateral wall of described roller is provided with ring-shaped step, the sidewall of described ring-shaped step be slope; The end of described car body is installed with motor, and described motor and axletree are in transmission connection.
Described small rail car wheel, it is characterized in that: the bottom hung of described car body has steel rope.
The beneficial effects of the utility model:
The utility model is simple in structure, reliable, adopts duplex bearing that roller is installed, and has strengthened the installation strength of roller, makes the stressed balanced more of roller, thus the service life of having improved car body; In addition, the utility model is designed to slope with the face that roller contacts with track, and the resistance when having reduced to slide has improved work efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of small rail car wheel, include two parallel tracks 1 and car body, be provided with axletree 2 in the car body, the two ends of axletree 2 are stretched out from car body respectively and by duplex bearing 3 roller 4 are installed respectively, roller 4 place respectively on two parallel tracks 1 and with two parallel track 1 bearing fits, the lateral wall of roller 4 is provided with ring-shaped step 5, the sidewall of ring-shaped step 5 is a slope; The end of car body is installed with motor 6, and motor 6 is in transmission connection with axletree 2.
The bottom hung of car body is useful on the steel rope of hoisting heavy.
Claims (2)
1. a small rail car is taken turns, include two parallel tracks and car body, be provided with axletree in the described car body, it is characterized in that: the two ends of described axletree are stretched out from car body respectively and by duplex bearing roller are installed respectively, described roller places on two parallel tracks respectively and the slide parallel with two cooperates, the lateral wall of described roller is provided with ring-shaped step, and the sidewall of described ring-shaped step is a slope; The end of described car body is installed with motor, and described motor and axletree are in transmission connection.
