Externally meshing paper roll clamp

Abstract

The invention discloses an externally meshing paper roll clamp. A swing gear (3) of the externally meshing paper roll clamp is of an external tooth structure and compassed of an inner ring and an outer ring. Steel balls are installed between the inner ring and the outer ring, and the inner ring and the outer ring rotate relatively. The inner ring is fixed to a rear base plate assembly (12). A gear on the outer ring meshes with a speed reducer (54) of a hydraulic system, namely the swing gear (3) meshes with the reducer (54) in an externally meshing mode. The externally meshing paper roll clamp has the advantages that the swing gear meshes with the reducer in the externally meshing mode, so that the horizon is greatly improved, and the requirement for the torque of a hydraulic motor is low.

Description

technical field [0001] The invention relates to special attachments for forklifts in industrial vehicles, in particular to a paper roll clamp for forklifts. Background technique [0002] With the rapid development of my country's paper industry, providing high-efficiency, fast and safe paper roll clamps is one of the main challenges for forklift attachment manufacturers. It is particularly important to provide a high-efficiency, fast and safe paper roll clamp for the paper industry . [0003] The patent number is 201220297226.9, and the patent titled "New paper roll clamp for forklift" discloses a new type of paper roll clamp for forklift that can work efficiently, prevent paper roll damage, and more reliably clamp paper rolls. The bottom plate assembly of the gear, the hook assembly, the rotary gear, the jig arm assembly for clamping the paper roll, and the hydraulic system assembly. The hydraulic system assembly consists of an oil cylinder assembly, a rotary oil supply val...

AI Technical Summary

Problems solved by technology

[0004] During the use of the above-mentioned existing paper roll clamp structure, some problems are gradually exposed. For example, the field of vision is not wide, and the clamping situation of the paper roll directly in front of the paper roll clamp cannot be observed. During the rotation of the clamp arm assembly, it often It conflicts with the pin shaft of the oil cylinder. After a long time, it will wear the pin shaft of the oil cylinder and cause the instability of the oil cylinder. In addition, because the reducer and the slewing bearing adopt the internal meshing method, it has a direct impact on the field of view of the slewing center; The way of meshing increases the torque requirement of the hydraulic motor
