Special perforated speed reducer for straight thread rolling machine

Abstract

The invention discloses a special perforated speed reducer for a straight thread rolling machine. The special perforated speed reducer structurally comprises a motor receiving disc, a pin wheel housing, a pin, a pin sleeve, a pendulous reed, an input shaft, an input shaft bearing, an eccentric bearing, an output shaft, a machine base bearing I, a machine base bearing II, a speed reducer machine base and a machine base end cover which are sequentially installed from left to right. The motor receiving disc and the pin wheel housing are designed into a whole. The pendulous reed is installed in the pin and the pin sleeve and connected with a groove in the pin wheel housing in a matched mode. One end of the input shaft is connected with the input shaft bearing, and the other end of the input shaft is installed in the pendulous reed of the pin wheel housing. The input shaft bearing is connected with the eccentric bearing, and the other end of the eccentric bearing is connected with the output bearing. The output bearing is sequentially connected with the output shaft, the machine base bearing I and the machine base bearing II. The other end of the machine base bearing II is connected with the speed reducer machine base and the machine base end cover. The special perforated speed reducer can effectively solve the problems existing in the prior art, is an expansive technological innovation for the prior art, and therefore has good application and popularization value.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a special perforated reducer for straight thread rolling machines. Background technique [0002] Steel bar straight thread rolling machine is a kind of steel bar processing machine widely used in construction industry in recent years. It quickly and directly rolls the end of the steel bar at one time to cause cold hardening at the head of the threaded wire, thereby improving the strength and making the steel wire head the same as the base material. It consists of a frame, a clamping mechanism, a feed carriage, a reducer, a thread rolling head, a cooling system, and an electrical system. [0003] Since the reducer is installed and fixed on the support assembly, it is an ordinary reducer product purchased from the market. The current reducer on the market has poor stability due to the base design not matching it. The design of the reducer base in patent CN206702140U is from I...

Problems solved by technology

[0003] Since the reducer is installed and fixed on the support assembly, it is an ordinary reducer product purchased from the market. The current reducer on the market has poor stability due to the base design not matching it. The design of the reducer base in patent CN206702140U is from It has been improved and upgraded to a certain extent, and its advantages after improvement are still great. With the improvement of technical requirements, there are also requirements for the accuracy of movement during normal operation, and certain requirements for torque and rigidity.
