Description

Device for increasing cutting capacity of table saw

Technical Field

The utility model relates to a bench saw device, concretely relates to bench saw increases cutting capacity's device.

Background

The existing table saw generally realizes one-stage transmission through two gears, the maximum cutting capacity is influenced by the center distance of the gears and the size of a motor shell, 8 'table saws are generally about 60mm, 10' table saws are generally about 80mm, and the cutting capacity of the existing table saw is limited.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a bench saw increases cutting ability's device solves the not enough problem of current bench saw cutting ability under the condition that does not increase the machine appearance.

The technical scheme is as follows: bench saw increase cutting ability's device, including taking tooth motor shaft, transmission shaft and output shaft, install first gear and second gear on the transmission shaft, install the third gear on the output shaft, take the tooth motor shaft with first gear engagement, the second gear with third gear engagement, the motor shaft rotates the drive first gear rotation and then drive transmission shaft rotates, the transmission shaft drives second gear rotation, the second gear drives third gear rotation and then drive output shaft rotates.

The first gear, the second gear and the third gear are mounted within a gear box.

In order to make the transmission between each component smoother, a bearing is arranged between one end of the rotating shaft and the motor shaft, and the other end of the rotating shaft is arranged in the bearing cover through the bearing. One end of the output shaft is installed in the bearing cover through a bearing, and the other end of the output shaft is installed in the gear box through a bearing.

In order to enable the gear to be meshed with the gear shaft at a corresponding position, the gear is positioned, and a spacer bush is arranged between the output shaft and the third gear.

Has the advantages that: the utility model discloses a two-stage transmission is realized to 3 gears, and then makes output shaft center and motor casing center offset the biggest, increases the cutting ability of bench saw, all is furnished with the bearing at the relevant position of output shaft, transmission shaft and motor shaft, makes the rotation between the three rotate between the bearing, makes the transmission between each part more smooth and easy, has also reduced the production of noise.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1-2, the utility model discloses a bench saw increases cutting capacity's device, including taking tooth motor shaft 1, transmission shaft 2 and output shaft 3, install first gear 4 and second gear 5 on the transmission shaft 2, install third gear 6 on the output shaft 2, take tooth motor shaft 1 with first gear 4 meshing, second gear 5 and third gear 6 meshing, motor shaft 1 rotates the first gear 4 of drive and rotates and then drive transmission shaft 2 and rotate, and transmission shaft 2 drives second gear 5 and rotates, and second gear 5 drives third gear 6 and rotates and then drive output shaft 2 and rotate. The first gear 4, the second gear 5 and the third gear 6 are arranged in a gear box 10, a bearing 7 is arranged between one end of the rotating shaft 2 and the motor shaft 1, the other end of the rotating shaft is arranged in a bearing cover 8 through the bearing 7, and a spacer 9 is arranged between the output shaft 2 and the third gear 6.

When using the utility model discloses the time, the motor rotates, the tooth of 1 end of motor shaft and the meshing of transmission epaxial first gear 4, transmission shaft 2 rotates, transmission shaft 2 epaxial second gear 5 and the meshing of the epaxial third gear 6 of output shaft 2, output shaft 2 rotates, the saw bit is installed at the 2 axle heads of output shaft, the machine can work, in order to further increase the cutting ability of saw bit, be close to table surface with output shaft 2 as far as possible, make the saw bit maximize expose table surface, make the saw bit have the biggest area. In order to make the transmission among all parts smoother, the bearings are arranged at the corresponding positions of the output shaft, the transmission shaft and the motor shaft, so that the rotation among the output shaft, the transmission shaft and the motor shaft rotates among the bearings, and the noise is reduced. The utility model discloses a 3 gears, second grade transmission realize that output shaft center and motor casing center offset are the biggest, and the complete machine saw bit is though only 8 ", but reaches 10" cutting ability.
