Abstract

The utility model discloses a coupling gear shaft. The coupling gear shaft comprises a rod and a shaft sleeve, wherein a gear is arranged at one end of the rod, the shaft sleeve is sheathed on the rod, an end surface cam is arranged at one end of the shaft sleeve, and an outer ring of the shaft sleeve is of a bearing guard. The coupling gear shaft is combined by two parts which are mutually independent, and after the shaft sleeve is removed, the gear can conveniently perform gear grinding on a gear grinding machine to compensate for deformation caused by quenching. In addition, if a fault occurs in the shaft sleeve part, only the shaft sleeve needs to be replaced, and the maintenance cost when the fault occurs can be further greatly reduced.

Description

The attachment tooth axle
Technical field
The utility model relates to a kind of planetary gear speed reducing mechanism, relates in particular to a kind of attachment tooth axle of planetary gear speed reducing mechanism.
Background technique
Characteristics such as planetary speed reducer is in light weight, volume is little, gear range is big, efficient is high, running is steady, the low adaptability of noise is strong.Speed reducer is widely used in industrial departments such as metallurgy, mine, lifting transportation, electric power, the energy, building materials, light industry, traffic.
The attachment tooth axle is passing planetary gear reducing mechanism for the motion with reducing gear.Referring to Fig. 1, the attachment tooth axle comprises bar 1, and the end of bar 1 is for supporting shelves 11.Be connected with an end cam 2 on one end of described bar 1, an end of described end cam 2 is provided with gear 3, and the outer ring of end cam 2 is provided with bearing guard 21.The bar 1 of original attachment tooth axle, end cam 2 and gear 3 all are one.
In order to guarantee hardness, support shelves 11, end cam 2 and gear 3 and all will after quenching, could use, and this step of quenching can make and part generation deformation makes the form and position tolerance of attachment tooth axle exceed standard.So these parts need could be used through after the grinding.Grinding was not easy very much after but the gear in the integral structure 3 deformed.Therefore no matter any part of attachment tooth axle breaks down in addition, all will change whole part, also maintenance cost greatly.
Summary of the invention
The utility model provides a kind of attachment tooth axle at deficiency of the prior art, makes things convenient for grinding, and maintenance cost also reduces greatly simultaneously.
For solving the problems of the technologies described above, the utility model is solved by following technical proposals: the attachment tooth axle comprises bar and axle sleeve, one end of described bar is provided with gear, described axle sleeve is enclosed within on the described bar, and an end of described axle sleeve is an end cam, and the outer ring of described axle sleeve is bearing guard.The attachment tooth axle is combined by two separate parts, takes off after the axle sleeve, and gear is roll flute on gear grinding machine easily, the distortion that compensation is quenched and caused.In addition, if shaft sleeve part is divided fault taking place, only need to change axle sleeve and get final product, therefore also greatly reduces the maintenance cost when breaking down.
In the technique scheme, preferred, described axle sleeve is provided with back-up ring.Bearing is installed on the bearing guard, and back-up ring contacts with the inner ring of bearing, and back-up ring plays a positioning action.
In the technique scheme, preferred, an end of described bar is provided with and supports shelves.
In the technique scheme, preferred, the end face of described bar is provided with the hole.
In the technique scheme, preferred, described bar is provided with key, and described axle sleeve is provided with the keyway that matches with described key.The employing keyway cooperates, cooperates reliably, and easy accessibility.
The beneficial effects of the utility model are: the attachment tooth axle is combined by two separate parts, takes off after the axle sleeve, and gear is roll flute on gear grinding machine easily, the distortion that compensation is quenched and caused.In addition, if shaft sleeve part is divided fault taking place, only need to change axle sleeve and get final product, therefore also greatly reduces the maintenance cost when breaking down.
