Spline shaft with high torque force

Abstract

The invention relates to a spline shaft with high torque force. The spline shaft with high torque force comprises a rotational member, a drive group and a forelock group, wherein the drive group is sleeved with the rotational member along an axial line, and the rotational member is provided with a plurality of first half slots formed on an external surface; the drive group is provided with a plurality of second half slots formed on an internal surface; and the forelock group is provided with a plurality of cylindrical keys and at least two limiting pieces, wherein the cylindrical keys are respectively arranged between the first half slots and the second half slots, and the two limiting pieces ensure that the cylindrical keys and the drive group are linked. Through adopting the characteristics of convenient processing of the half slots and matching the limited cylindrical keys, the spline shaft with high torque force achieves the purposes of simplifying manufacture procedures, reducing cost, increasing precision and improving processing benefits without influencing a drive torque.

Description

technical field [0001] The invention relates to a pinch shaft, in particular to a high torque pinch shaft for power transmission. Background technique [0002] refer to figure 1 , taking the general keyway shaft 1 as an example, it mainly includes a rotating member 11 extending along an axis X direction, and a transmission member 12 . The rotating member 11 is driven by a power source to rotate, and has several pegs 111 formed on an outer surface around the axis X. The transmission member 12 has a shaft hole 121 passing through along the axis X and fitted with the transmission member 12 , and a plurality of bolt grooves 122 formed on an inner surface and matched with the bolt key 111 . Thereby, the transmission member 12 and the rotating member 11 are linked to each other through the mating relationship between the bolt key 111 and the bolt groove 122 , and the transmission member 12 or the rotating member 11 is allowed to move along the axis X. [0003] Generally speakin...

AI Technical Summary

Problems solved by technology

[0007] However, since the aforementioned ball 34 is in point contact with the rotating member 31 and the transmission member 32 and is in a freely rotatable state, the retainer 33 must be added to maintain the stability of the aforementioned ball 34 and improve overall performance. Torque, not only more components, but also increases the complexity of installation

[0008] This shows that the above-mentioned existing keyway shaft obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
