Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a flying saw main shaft speed reducer. Background Art

[0002] A flying saw is a high-speed cutting device typically used for quickly and efficiently cutting metal and other hard materials. The spindle reducer reduces speed and increases torque, converting the high-speed rotation of the motor into a low-speed, high-torque output suitable for the flying saw's spindle, thereby ensuring stable operation and efficient cutting. The working principle of a flying saw spindle reducer is to convert the high-speed input rotation through a reduction gear into a low-speed, high-torque output suitable for the flying saw's spindle.

[0003] The spindle reducer used in the existing cold-cut flying saw adopts an imported parallel shaft gear reducer. The reducer is large in size and heavy in mass, resulting in a large weight and bulky fast-moving machine head, which cannot move quickly. In addition, the imported reducer is expensive. Therefore, a small-sized and high-torque flying saw reducer device is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a flying saw spindle reducer to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The corner box includes a first shell, an input shaft is rotatably mounted on the upper inner part of the first shell through a bearing, a first bevel gear is fixedly mounted on the inner end of the input shaft, a transmission shaft is rotatably mounted on the bottom inner part of the first shell through a bearing, a second bevel gear is fixedly mounted on the inner end of the transmission shaft and the second bevel gear is meshed with the first bevel gear.

[0008] As a further solution of the present invention: the number of teeth on the second bevel gear is greater than the number of teeth on the first bevel gear.

[0009] As a further solution of the present invention: the planetary reduction mechanism includes a second housing and a sun gear, the sun gear is fixedly arranged at the outer end of the transmission shaft, a ring gear is arranged on the outside of the sun gear and the ring gear is fixedly connected to the inner wall of the second housing, a number of planetary gears are arranged between the sun gear and the ring gear and the planetary gears are meshed with the sun gear and the ring gear, and a planetary transmission seat is installed in the planetary gear through a bearing.

[0010] As a further solution of the present invention: the planetary transmission seat passes through the main shaft bearing seat, the main shaft bearing seat includes a third shell and a first bearing, the first bearing is arranged on the planetary transmission seat, and a second bearing is arranged on the planetary transmission seat to the right of the first bearing.

[0011] As a further solution of the present invention: the saw blade clamping mechanism includes a base, the base is arranged on the outside of the planetary transmission seat, a clamping plate is arranged on the right side of the base on the planetary transmission seat, the outer end of the planetary transmission seat is provided with a thread, and a nut is threadedly installed on the outer end of the planetary transmission seat.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The power is transmitted to the corner box through the spindle motor. The corner box changes the transmission direction, which is convenient for the installation of the spindle motor. The planetary reduction mechanism and the spindle bearing seat cooperate to transmit the power to the saw blade clamping mechanism, thereby improving the operating efficiency of the device. It has the advantages of high efficiency, low cost, small size, etc., saving space and significantly reducing the weight of the mobile head.

[0014] 2. The power input by the spindle motor is received through the input bearing. The first bevel gear and the second bevel gear cooperate to initially reduce the speed of the input shaft, thereby initially increasing the torque of the device. The sun gear and the planetary gears reduce the speed again and transmit the power on the transmission shaft to the planetary transmission seat. This can achieve higher transmission efficiency and more precise transmission, making the structure compact and taking up less space, which not only saves costs but also improves the energy utilization efficiency of the device.

[0015] 3. The planetary transmission seat is initially limited by the first bearing, and the second bearing is used to limit the planetary transmission seat for the second time, which can ensure that the axis of the planetary transmission seat remains stable and improve the stability of the device operation. The base and the clamping piece initially clamp the saw blade, and the threaded nut at the end of the planetary transmission seat further clamps the saw blade. The saw blade is directly installed at the output end of the reducer to achieve the purpose of clamping the saw blade and direct power output. BRIEF DESCRIPTION OF THE DRAWINGS
