Bearing type transmission wheel

Abstract

The invention discloses a bearing type transmission wheel and aims to provide a transmission wheel which is simple in structure, convenient to maintain, durable in use, zero in relative friction in operation and has replaceable single tooth. According to the key points of the technical scheme, the whole transmission wheel is made in a combined type, at least 1 / 2 of teeth are replaced by a rotating wheel which consists of a bearing and an outer sleeve and are arranged on a small shaft, the other 1 / 2 of teeth can be engaged and disengaged without an error during meshed operation of a master transmission wheel and a slave transmission wheel in the structure and shape, namely the transmission wheel can be in a shape of a plate or an arc opening fork or an acute angle, an obtuse angle and a right-angle opening, the teeth of a large transmission wheel are arranged on a plurality of upright posts which can slide and lift in a certain size inwards and outwards at the periphery of the outer edge of the transmission wheel in equal distance, so that the occupied contours are increased from engagement to disengagement due to the lifting action of the upright posts during operation, and therefore, the transmission efficiency is invariable.

Description

technical field [0001] The present invention relates to the transmission parts in the machine, more precisely and more specifically the meshing transmission of two gears or more than two gears in the conventional. Background technique [0002] Gear transmission is one of the most commonly used transmission methods in modern machines. This is because it can maintain a constant transmission ratio, that is, the speed of each gear at the same time is determined according to the number of teeth on the master and slave gears, that is, the driving wheel is smaller than the driven wheel for deceleration, and vice versa for speeding up, and the transmission power range is large. , as small as clocks and watches as large as hundreds of thousands of kilowatts, and the transmission efficiency is high, unlike belt transmission, which more or less slips and reduces transmission efficiency. [0003] According to the meshing mode, it can be divided into external meshing transmission, inter...

Problems solved by technology

[0004] In the prior art, the deficiencies of the gear transmission are that no matter any gear and any transmission mode, relative friction cannot be avoided. The adverse consequences of friction are wear, heat, noise and stability. Second, it is prone to broken teeth, which need to be repaired if it is light, or scrapped as a whole if it is serious; third, lubricating oil must be added to reduce friction, which is why the gear box is equipped, or it is troublesome and expensive to supply oil by means of an oil pump , and after the gear is formed, its outer diameter cannot be changed, and there is no room for adjustment of the center distance between the master and slave gears during installation, etc.
