Description

The power bi-shunting speed reducer all carried

Technical field

The utility model relates to a kind of speed reducer, especially a kind of containing load balancing mechanism power bi-shunting speed reducer, belong to a kind of driving of parallel axes for building material industry power bi-shunting speed speed reducer.

Background technique

The concrete drive path of power bi-shunting speed speed reducer of the driving of parallel axes of building material industry is: power is inputted by mair motor, shunt to two the one-level gearwheels engaged with it simultaneously through one-level small gear, secondary small gear is passed to again by one-level gearwheel, then engage with secondary gearwheel through two secondary small gears simultaneously, export to grinding machine by output shaft.Load balancing mechanism requires that load shared by several gear exactly, make power dividing, namely to ensure that four pairs of gears engage simultaneously, current load balancing mechanism used, when speed reducer is installed, adjust after four pairs of gears engage simultaneously, be fixed for adjusting by the mode of making locating stud and bolt and the gear of location, end temporarily.The deficiency of this load balancing mechanism is: during assembling, needs first to be pulled down from speed reducer by two parts making locating stud, changes spare part just more inconvenient as located user, and the leeway do not adjusted again, can not change the sense of rotation of speed reducer.How to solve the problem, make speed reducer more perfect, become the problem that people pay close attention to.

Model utility content

The purpose of this utility model is: what exist for current load balancing mechanism need pull down two parts making locating stud from speed reducer, locate to change spare part user inconvenient, the leeway do not adjusted again, the practical problems such as the sense of rotation of speed reducer can not be changed, a kind of power bi-shunting speed reducer all carried newly is provided.

The purpose of this utility model is achieved in that a kind of power bi-shunting speed reducer all carried, input gear axle, splitting parallel axle, output shaft, splitting parallel axisymmetric is positioned at the both sides of input gear axle and output shaft, they all by bearings in casing, in splitting parallel axle, symmetrical gearwheel engages with input gear axle simultaneously, another symmetrical gear engages with the gearwheel on output shaft simultaneously, it is characterized in that:

A) the splitting parallel axle described in comprises hollow shaft, the hollow pinion shaft of secondary and flexible shaft, and flexible shaft passes through hollow shaft and the hollow pinion shaft of secondary, hollow shaft is installed with the gearwheel engaged with input gear axle;

B) input gear axle and output shaft are positioned on same medial axis, output shaft are installed with output gearwheel;

C) two symmetrical hollow shafts connect with corresponding flexible shaft respectively, and in two hollow pinion shafts of secondary of symmetry, one is connected with flexible shaft by coning sleeve, and another is connected with flexible shaft with shrink disk by hollow connecting shaft.

In the utility model, described input gear axle is supported in casing by a pair selfaligning bearing, hollow shaft, secondary pinion shaft and output shaft respectively by pair of sliding bearings in casing.

The utility model has the advantage of: because group flexible shaft of in load balancing mechanism adopts traditional orientation type, another group flexible shaft adopts the mode of hollow connecting shaft and shrink disk location, which not only improves the accuracy of manufacturing efficiency and transmission, and extend the life cycle of spare part, further when user has special requirement, through adjustment, the sense of rotation of speed reducer can be changed; Owing to have employed flexible shaft, greatly can improve and all carry performance; Owing to one-level pinion shaft being equipped with except selfaligning bearing except inputting, hollow shaft, secondary pinion shaft and output shaft are provided with sliding bearing, are achieving under the condition of all carrying, are also improving the bearing capacity of speed reducer.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment.

In figure: 1, input gear axle, 2, gearwheel, 3, flexible shaft, 4, hollow shaft, 5, secondary pinion shaft, 6, coning sleeve, 7, secondary bull gear, 8, output shaft, 9, hollow connecting shaft, 10, shrink disk.

Embodiment

Accompanying drawing discloses the concrete structure of a kind of embodiment of the utility model without limitation, and below in conjunction with accompanying drawing, the utility model will be further described.

As seen from Figure 1: the utility model is made up of the parts such as input gear pair, hollow shaft 4, flexible shaft 3, coning sleeve 6, secondary gear wheel set, shrink disk 10, hollow connecting shaft 9, output shaft 8, input gear pair comprises input gear axle 1 and gearwheel 2, secondary gear wheel set comprises the hollow pinion shaft 5 of secondary and exports gearwheel 7, wherein: described flexible shaft 8 passes through hollow shaft 4 and the hollow pinion shaft 5 of secondary, hollow shaft 4 is installed with the gearwheel 2 engaged with input gear axle; Input gear axle 1 and output shaft 8 are positioned on same medial axis, output shaft 8 is installed with and exports gearwheel 7; Two symmetrical hollow shafts 4 connect with corresponding flexible shaft 3 respectively, and in the hollow pinion shaft 5 of two secondarys of symmetry, one is connected with flexible shaft 4 by coning sleeve 6, and another is connected with flexible shaft 4 with shrink disk 10 by hollow connecting shaft 9.

During concrete enforcement, described input gear axle 1 is supported in casing by a pair selfaligning bearing, hollow shaft 4, secondary pinion shaft 5 and output shaft 8 respectively by pair of sliding bearings in casing.

The power transmission process of illustrated embodiment is: moment of torsion divides two-way to pass to gearwheel 2 by input gear axle 1, gearwheel 2 drives hollow shaft 4, hollow shaft 4 drives flexible shaft 3, flexible shaft 3, by coning sleeve 6 or hollow connecting shaft 9 and shrink disk 10, moment of torsion is passed to secondary pinion shaft 5, two-way secondary pinion shaft 5 again moment of torsion is collected pass to export gearwheel 7, export finally by output shaft 8.

In actual use, each axle related to all is horizontal the utility model.
