Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] First, according to the shape and size of the gear teeth and the inner ring of the ratchet 1, process a single part that is integrated with the gear sleeve 3 and the connecting piece 4 with a suitable process, and then insert this part on the gear teeth and the inner ring of the ratchet 1. On the ring, welding or bonding technology can be used to make the inlay more firm. After being put into use, the ratchet 2 no longer contacts the gear teeth of the ratchet 1, but contacts the gear teeth through the tooth sleeve 3, so that the ratchet gear teeth are well protected. Through the use of a maintenance cycle, the gear sleeve 3 is normally worn to the point where it needs to be replaced, as long as the old gear sleeve 3 and the connecting piece 4 are folded off, and a new one is replaced. The folding operation takes only a short time and co...

Abstract

The invention discloses a ratchet device equipped with ratchet gear teeth with tooth sleeves, belonging to the technical field of ratchet mechanisms and used for overcoming the disadvantages that the ratchet gear teeth and jaws of the traditional ratchet device are very easy to abrade and have short service life, and device failure is usually caused by the cutting of the ratchet gear teeth or fracture of jaws. The ratchet device provided by the invention comprises the ratchet and the jaws; the ratchet gear teeth are equipped with teeth sleeves; and the gear sleeves are connected together by connecting sheets. The ratchet device provided by the invention is suitable for various ratchet devices.

Description

technical field [0001] The invention relates to a ratchet mechanism technology, in particular to a ratchet device in which the teeth of the ratchet wheel are covered with gear sleeves. Background technique [0002] Ratchet mechanism is a kind of transmission mechanism widely used in mechanical equipment. It is composed of ratchet, pawl, connecting rod, etc. to achieve the purpose of intermittent movement. Generally, there are two kinds of transmission forms of the ratchet mechanism. One is that the connecting rod drives the pawl to do reciprocating motion, and the pawl moves the ratchet gear teeth to drive the ratchet to do one-way intermittent motion; the other is that the transmission part drives the ratchet intermittently. The ground rotates clockwise and counterclockwise, and through the cooperation of the teeth of the ratchet and the pawl, the force of the ratchet rotation is transmitted to the pawl, so that the pawl drives the parts connected to it to rotate intermitte...
