Guide wheel structure with high bearing capacity

Abstract

The invention provides a guide wheel structure with high bearing capacity. The guide wheel structure comprises a guide wheel shaft, a guide wheel spacer, a horizontal wheel sleeve, a horizontal wheel end cover, a transition wheel sleeve and a bearing, wherein the guide wheel spacer and the bearing area respectively mounted on the guide wheel shaft; one end of the guide wheel spacer is close to a device body; the other end of the guide wheel spacer is next to the bearing; the horizontal wheel sleeve is mounted on the bearing, and is connected with the horizontal wheel end cover; and the transition wheel sleeve is mounted between the guide wheel shaft and the device body. The guide wheel structure is high in bearing capacity when being used for guiding, and can bear a certain axial force. The guide wheel structure is concise in structure, is easy to implement, can realize batch production, is suitable for different devices, realizes the bearing and guiding effects, and is a guiding structure or a bearing structure used for various movement systems.

Description

technical field [0001] The invention relates to the walking and lifting structural equipment of a fork device in the field of mechanical equipment, in particular to a structure of a large load-bearing guide wheel. Background technique [0002] The existing guide wheel structure usually uses a guide bearing or a separately enlarged guide structure, and the selection of a guide bearing or a separately enlarged guide structure usually has the following defects: [0003] 1. Select the guide bearing. Because the structure of the guide bearing is single and the bearing capacity is small, it is generally unable to bear the axial force; [0004] 2. To make a large guide structure separately, it is time-consuming and troublesome to design the guide structure separately, and the guide structure designed separately is usually large and heavy. [0005] Due to the existence of the above-mentioned defects, the existing guide wheel structure cannot really meet the walking and lifting requ...

Problems solved by technology

[0004] 2. To make a large guide structure separately, it is time-consuming and troublesome to design the guide structure separately, and the guide structure designed separately is usually large and heavy

[0007] 1. The bearing capacity is small, suitable for general bearing mechanisms;

[0008] 2. In the absence of a special oil circuit, it is not suitable for high-speed operating machinery and equipment;

[0009] 3. It cannot bear the force in the axial direction of the guide wheel, and is only suitable for structural load under longitudinal compression
