Description

Technical Field

[0001] This utility model relates to the field of drive device technology, and in particular to an electric rubber-coated wheel. Background Technology

[0002] Rubber-coated wheels, also known as rubber tires, are circular, elastic rubber wheels mounted on various vehicles or machinery. They are typically installed on metal rims and serve to support the vehicle body, buffer external impacts, reduce vibration, and lower temperatures. They are widely used in various processing industries and conveyor systems. However, due to the different material properties and application ranges of rubber-coated wheels, some require special modifications to be suitable for certain scenarios. In traditional low-speed, high-load transportation industries, the harsh working environment necessitates frequent replacement of the rubber rings on rubber-coated wheels to prevent slippage, with the number of slippages increasing exponentially. Reducing slippage during the use of rubber-coated wheels can significantly extend their service life. Utility Model Content

[0003] The purpose of this invention is to provide an electric rubber-coated wheel to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An electric rubber-coated wheel includes a hub on which a rubber wheel is fitted. The hub's axis is horizontally oriented. The hub is integrally formed from a rim and a wheel frame located on the left side inside the rim. A rotating shaft passes through the hub, allowing the hub to rotate axially relative to the shaft. A bracket is fixedly mounted on the right end of the shaft, and a scraper is mounted on the top of the bracket. The blade of the scraper is in contact with the outer rim of the rubber wheel. A drive motor is fixedly mounted on the left end of the shaft, located inside the hub. The drive motor drives the hub to rotate axially. The blade is tangent to the outer ring of the rubber wheel. The bracket includes a first vertical rod, a second vertical rod, and a crossbeam. The first and second vertical rods are spaced apart and installed at the top right end of the rotating shaft. The top ends of the first and second vertical rods are provided with sliding grooves that extend from left to right. The crossbeam passes through the top sliding grooves of the first and second vertical rods from left to right. The crossbeam is installed in the sliding grooves that slide up and down. One end of a tension spring is fixedly installed at the bottom right end of the crossbeam. The other end of the tension spring is fixedly installed on the rotating shaft. The right end of the scraper is fixedly connected to the left end of the crossbeam.

[0006] By adopting the above technical solution, in the field of low-speed electric rubber-coated wheels, a relatively large torque is generally required. Therefore, it is necessary to maintain a certain level of cleanliness on the surface of the rubber wheel to keep the relative friction between the rubber wheel and the ground within a certain range. To prevent the rubber wheel from accumulating too much dust on the ground during travel, a scraper that can move and adhere to the surface of the rubber wheel is set up to maintain the cleanliness of the rubber wheel surface, reducing the requirements for the ground surface. In this solution, the drive motor is a hub motor. In order to better install the rubber wheel, a traditional hub is fitted on the outside of the hub motor.

[0007] In a further embodiment, a semi-circular outer shell is fixedly installed on the left end of the rotating shaft. The semi-circular outer shell is used to cover the top area of ​​the wheel hub. There is a gap between the inner wall of the semi-circular outer shell and the outer surface of the rubber wheel. An avoidance hole is provided on the right end of the semi-circular outer shell. The avoidance hole is used for, for example, a scraper.

[0008] By adopting the above technical solution, the scraper can be prevented from flying off and injuring people in case of accidents.

[0009] In a further embodiment, multiple tension springs are provided, and tension springs are fixedly installed on the inner bottom of each slide groove.

[0010] By adopting the above technical solution, the tensile force on the beam is made more balanced.

[0011] In a further embodiment, a bearing housing is fitted onto the right end of the rotating shaft.

[0012] In a further embodiment, the bottom ends of both the first and second vertical rods are welded and fixed to the rotating shaft.

[0013] In a further embodiment, the right end of the scraper is provided with a through hole, the left end of the crossbeam is provided with a threaded hole, and the scraper is bolted and fixed to the left end of the crossbeam.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. A scraper that can move and adhere to the surface of the rubber wheel is set on the surface of the rubber wheel to keep the surface of the rubber wheel clean, reducing the requirements for the ground.
