The prior transmission device technology of the injection molding machine has the following problems: on an injection molding machine, the injection is very important, but the feeding is realized on the basis of very smooth charging, so the force transmission between a hydraulic actuating element and a screw is very important, and the continuity of the feeding can be ensured.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel injection molding machine transmission to the transmission of the power that proposes current injection molding machine hydraulic actuator and screw rod among the above-mentioned background art is smooth and easy problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel injection molding machine transmission, includes motor fixing base and fixing bearing, fixing bearing installs the inside at the motor fixing base, fixing bearing's inside is provided with the transmission shaft, the inside bearing cap that is provided with of motor fixing base lower extreme outer wall, be provided with deep groove ball bearing on the motor fixing base of transmission shaft upside, motor fixing base upper end outer wall inside is provided with the fixed orifices.

Preferably, the self-aligning roller bearing is sleeved on the transmission shaft.

Preferably, the bearing cover is fixedly connected with the motor fixing seat through threads.

Preferably, the deep groove ball bearing is sleeved between the motor fixing seat and the transmission shaft.

Compared with the prior art, the utility model provides a novel injection molding machine transmission possesses following beneficial effect:

the utility model discloses compare with traditional transmission, at first on the material, this transmission adopts nodular cast iron, the shock attenuation, inhale shake because the 45# jar, the wearability is good, improve the fracture phenomenon often appears in the 45#, the transmission shaft has axial and radial power, traditional transmission has adorned deep groove ball bearing and thrust bearing, but only solved radial force, axial force is guided by the bush is rigid, a time long bush has just worn and torn, the dead phenomenon of card just appears in this device, this transmission has installed self-aligning roller bearing below, if upper and lower concentricity has the error, self-aligning roller bearing will absorb the axial force that has the concentricity error to cause, this transmission life is longer, the screw rod that also is favorable to the injection molding machine is in the reinforced of optimum condition assurance screw rod always.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a novel injection molding machine transmission, includes motor fixing base 1 and fixed bearing 4, and fixed bearing 4 installs in motor fixing base 1's inside, and fixed bearing 4's inside is provided with transmission shaft 6, and the inside bearing cap 5 that is provided with of 1 lower extreme outer wall of motor fixing base is provided with deep groove ball bearing 3 on the motor fixing base 1 of 6 upsides of transmission shaft, and the inside fixed orifices 2 that is provided with of 1 upper end outer wall of motor fixing base.

The utility model provides a novel injection molding machine transmission, includes motor fixing base 1 and fixed bearing 4, and aligning roller bearing overlaps on transmission shaft 6, makes aligning roller bearing absorb the axial force that has the concentricity error to cause like this, and the transmission life-span is longer, and bearing cap 5 passes through screw and 1 fixed connection of motor fixing base, fixes transmission shaft 6 like this, and 3 covers of deep groove ball bearing are in the middle of motor fixing base 1 and transmission shaft 6, make transmission shaft 6 have axial and radial power like this.
