Novel grease lubrication main shaft for multi-wire sawing machine

Abstract

The invention discloses a novel grease lubrication main shaft for a multi-wire sawing machine. The novel grease lubrication main shaft comprises a center shaft and a main shaft sleeve arranged outsidethe center shaft, the center shaft is an equal-diameter shaft, bearings are arranged between the center shaft and the main shaft sleeve, and the bearings comprise a front end bearing arranged at thefront end of the center shaft and a rear end bearing arranged at the rear end of the center shaft. The outer diameter of the front end bearing is larger than that of the rear end bearing, a main shaftinner cavity is formed between the front end bearing and the rear end bearing, internal pressure capable of preventing foreign matter from entering the main shaft inner cavity is formed in the main shaft inner cavity, the main shaft can meet the higher rotating speed requirement, and meanwhile the low heating capacity, the high heat dissipation capacity, the sealing capacity and the pollution discharge capacity are improved, so that the main shaft can be ensured to stably work at a high rotating speed.

Description

technical field [0001] The invention belongs to the field of multi-wire cutting equipment, and in particular relates to a novel grease-lubricated main shaft for multi-wire cutting machines. Background technique [0002] With the increase of the slicing process, the requirements for the linear speed of the main shaft of the slicing machine are also increasing. The original slicing main shaft is difficult to achieve a higher speed due to insufficient heating and cooling and sealing effect problems, which cannot meet the fine cutting process. The need for high-speed slicers. [0003] Therefore, prior art still needs further development and improvement. Contents of the invention [0004] Aiming at various deficiencies in the prior art, in order to solve the above problems, a new type of multi-wire cutting machine with grease lubricated main shaft is proposed. The main shaft has a high rotating speed and good cooling and blowdown effect. [0005] To achieve the above object, ...
