Problems solved by technology
[0002] The tension device is a core device in the linear drive. The quality of the tension device directly affects the operating efficiency of the linear drive. Although some of the existing tension devices are relatively mature in technology, the components in the tension device are not stable during operation. The strength of the force is high, so the wear is also very large, resulting in a short service life of the parts. Due to the wear of the parts, the tension output of the entire tension device will also be unstable, which affects the operating efficiency of the linear drive.

The invention discloses a tension device in a linear driver. The device comprises an iron body and further comprises an internal expansion follow-up brake, wherein the iron body and the internal expansion follow-up brake are fixedly connected through an isolation sleeve, the internal expansion follow-up brake is provided with two elastic retainer rings, two sides of the iron body are respectively provided with two pull boards and a rotation shaft symmetrically, and the rotation shaft is arranged between the two pull boards. Compared with the prior art, the tension device is provided with the internal expansion follow-up brake, starting and braking flexibility of the linear driver is greatly improved, fixing parts of the whole device are scientifically arranged, so the tension device has a quite firm structure, a wear rate of the internal expansion follow-up brake in operation can be effectively reduced through the elastic retainer rings, and thereby service life of the internal expansion follow-up brake is improved.
Description
technical field [0001] The invention relates to the field of motor drive equipment, in particular to a tension device in a linear drive. Background technique [0002] The tension device is a core device in the linear drive. The quality of the tension device directly affects the operating efficiency of the linear drive. Although some of the existing tension devices are relatively mature in technology, the components in the tension device are not stable during operation. The force is strong, so the wear is also very large, resulting in the short service life of the parts. Due to the wear of the parts, the pulling force output of the entire pulling device will also be unstable, which affects the operating efficiency of the linear drive. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, provide a tension device in a linear drive with high stability of tension output, firm structure, and low wear rate. [0004]...
