Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pinion shafts, in particular to a pinion shaft that is easy to process. Background Art
[0002] A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. It is generally a metal round rod, and each section can have different diameters. The parts that make rotating motion in the machine are installed on the shaft. The shaft and gear of the current gear shaft are mostly formed in one piece, which requires high processing accuracy during processing and is difficult to process. Therefore, we propose a small gear shaft that is easy to process. Utility Model Content
[0003] The purpose of the utility model is to provide a pinion shaft that is easy to process, so as to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a small gear shaft that is easy to process, comprising a shaft and a gear, the right side wall of the gear is provided with an opening that matches the shaft, the outer wall of the shaft is sleeved with a positioning plate, the left side wall of the positioning plate is penetrated by four groups of mounting rods, one end of the four groups of mounting rods are provided with adjustment knobs, the outer walls of the four groups of mounting rods are provided with threads, the outer walls of the mounting rods are threadedly connected with locking nuts, and the left side wall of the gear is penetrated by four groups of through holes that match the mounting rods.
[0005] Furthermore, the right side wall of the gear is provided with four groups of grooves matching with the locking nuts, and the grooves are connected with the through holes.
[0006] Furthermore, the four groups of grooves are distributed in a ring array on the right side wall of the gear.
[0007] Furthermore, the four groups of mounting rods are distributed in a circular array on the left side wall of the positioning plate.
[0008] Furthermore, the outer side wall of the shaft is provided with two groups of positioning strips, and the left side wall of the gear is provided with two groups of positioning grooves matching the positioning strips.
[0009] Compared with the prior art, the beneficial effects of the utility model are: the utility model processes the shaft and the gear separately, which reduces the processing accuracy and difficulty, and the gear can be conveniently fixed on the shaft for use with the cooperation of the positioning plate, the mounting rod, the threaded rod, the thread, the locking nut and the groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] Embodiment 1:
[0015] See also Figure 1-2 The utility model provides a technical solution: a small gear shaft that is easy to process, including a shaft 1 and a gear 9, the right side wall of the gear 9 is provided with an opening that matches the shaft 1, the outer side wall of the shaft 1 is provided with two groups of positioning strips 6, and the left side wall of the gear 9 is provided with two groups of positioning grooves 7 that match the positioning strips 6. Under the cooperation of the positioning block 6 and the positioning groove 7, the gear 9 can be fitted with the positioning plate 2, the outer wall of the shaft 1 is sleeved and installed with a positioning plate 2, and the left side wall of the positioning plate 2 is penetrated with four groups of mounting rods 3, and the four groups of mounting rods 3 are annular on the left side wall of the positioning plate 2 Array distribution, one end of the four groups of mounting rods 3 are provided with an adjusting knob 10, the outer walls of the four groups of mounting rods 3 are provided with threads 4, the outer walls of the mounting rods 3 are threadedly connected with locking nuts 5, the left side wall of the gear 9 is penetrated by four groups of through holes 8 matching the mounting rods 3, the right side wall of the gear 9 is provided with four groups of grooves 11 matching the locking nuts 5, the grooves 11 are connected with the through holes 8, the four groups of grooves 11 are arranged in a ring array on the right side wall of the gear 9, and the locking nuts 5 can be stored under the action of the grooves 11 to prevent the locking nuts 5 from being exposed to the outside.
[0016] Working principle: If the shaft 1 and the gear 9 are processed separately, the processing accuracy and difficulty will be reduced. They will be fixed together when used.
