Problems solved by technology

However, the disadvantage of copper nuts is that copper nuts have poor self-lubricating ability when used in severe temperature environments with large temperature changes. Under a dynamic load of 1 ton, taking the lifting distance of copper nuts as an example, the number of lifting times is less than 150 times. It is necessary to add lubricating grease frequently to ensure the smooth movement of it and the screw during the screw transmission process.
However, plastic nuts have the following disadvantages: the plastic material has poor strength and cannot bear large static loads and dynamic loads. If the length of a single nut is increased to withstand high static loads and dynamic loads, it can be used in harsh environments with large temperature changes. When used under high conditions, axial expansion will occur due to the large linear expansion coefficient of the plastic material

Abstract

The invention relates to a slotted push rod device adopting plastic nuts, which comprises an input shaft, an upper shell, a lower shell, a transmission device, a screw rod, plastic nuts and a metal pipe, the plastic nuts are of slotted plastic nut structures, and gaps are formed between the adjacent slotted plastic nuts. The slotted plastic nut structure is provided with two or more sections of slotted plastic nuts, and at least two or more sections of slotted plastic nuts in the slotted plastic nuts are fixedly connected with the metal pipe at the same time. The slotted plastic nut structure not only has good self-lubricating performance and does not need to be added with oil frequently, but also cannot be axially expanded in a severe temperature environment with a large temperature difference and under the condition that the slotted plastic nut structure bears a large load. The invention further relates to a production method of the slotted push rod device adopting the plastic nuts.

Description

technical field [0001] The invention belongs to the technical field of push rod devices, and in particular relates to a slotted push rod device using plastic nuts and a processing method thereof, in particular to a push rod device and a processing method suitable for solar power generation solar tracking brackets. Background technique [0002] The technology of using solar power generation devices to generate electricity is becoming more and more common around the world. In order to maximize the utilization of solar energy by solar power generation devices, the existing technology uses solar tracking brackets to realize solar sails in solar power generation devices.
