Description
Technical Field
The utility model relates to a fluid measurement field, in particular to gaseous roots flowmeter that bearing is external.
Background
A roots meter is a high precision meter used to measure flow in a pipe continuously or intermittently. The positive displacement flowmeter has the characteristics of high precision, good reliability, light weight, long service life, convenience in installation and use and the like, and is typical of a positive displacement flowmeter. The waist wheel generally is connected with the waist wheel axle, installs bearing and the synchronizing gear who is used for supporting on the waist wheel axle, and the tradition is with synchronizing gear as for the outside of bearing, and the bearing gets into impurity and wearing and tearing easily, owing to change the bearing and will dismantle synchronizing gear at first, dismantles synchronizing gear and can change the relative position of two waist wheels, consequently, the dismouting is maintained inconveniently.
With respect to the above problems, new solutions need to be provided.
SUMMERY OF THE UTILITY MODEL
Therefore, the present invention has been made in view of the above problems. The utility model discloses fall into two parts with the axle, convenient to detach and installation when changing the bearing. The utility model discloses a realize above-mentioned purpose through following technical scheme:
a gas waist wheel flowmeter with an external bearing mainly comprises: the device comprises a waist wheel, a first connecting shaft, a second connecting shaft, a screw, a synchronous gear and a bearing;
the gas waist wheel flowmeter is provided with two waist wheels which are consistent in size and tangent;
one end of each waist wheel is provided with a first connecting shaft, one end of each first connecting shaft is provided with a square slot, and the upper wall surface and the lower wall surface of each slot are provided with a first through hole of an internal thread communicated with each other; the synchronous gear is sleeved on the first connecting shaft; the connecting shaft II is arranged opposite to the connecting shaft I, one end of the connecting shaft II is provided with a square inserting block, and an internal thread through hole II is formed in the inserting block; the screw rod is respectively matched with the first internal thread through hole and the second internal thread through hole; and the bearing is sleeved on the second connecting shaft.
In one embodiment, the insert blocks and the slots are arranged in a regular hexagonal configuration.
In one embodiment, a chamfer is provided at a front section of the insert block.
The utility model discloses beneficial effect as follows:
1. the utility model discloses fall into connecting axle one and two parts of connecting axle with the axle, design like this can be according to the nimble dismantlement bearing of actual conditions, and it is simple, labour saving and time saving to dismantle with the installation.
Drawings
Fig. 1 is an overall view of the present invention.
Fig. 2 is a view of the first connecting shaft and the second connecting shaft of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are easily implemented by those having ordinary skill in the art to which the present invention pertains. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In addition, for the purpose of more clearly describing the present invention, parts not connected with the present invention will be omitted from the drawings.
A gas waist wheel flowmeter with an external bearing mainly comprises: the device comprises a waist wheel 1, a connecting shaft I2, a connecting shaft II 3, a screw 4, a synchronous gear 5 and a bearing 6;
as shown in fig. 1 and 2, the gas waist wheel flowmeter has two waist wheels 1 which are consistent in size and tangent; one end of each waist wheel 1 is provided with a first connecting shaft 2; one end of the connecting shaft I2 is provided with a square slot 21, and the upper wall surface and the lower wall surface of the slot 21 are provided with a first communicated internal thread through hole 22; the synchronous gear 5 is sleeved on the first connecting shaft;
the connecting shaft II 3 is arranged opposite to the connecting shaft I2, one end of the connecting shaft II 3 is provided with a square inserting block 31, and the inserting block 31 is provided with a second internal thread through hole 32; the insert block 31 is just matched with the slot 21, and the internal thread through hole I22 is vertically communicated with the internal thread through hole II 32; the screw rod 4 is respectively matched with the first internal thread through hole 22 and the second internal thread through hole 32;
the bearing 6 is sleeved on the second connecting shaft 3.
Preferably, as an implementation mode, the insertion block 31 and the insertion slot 21 are both arranged in a regular hexagon structure, so that the contact area between the first connecting shaft 2 and the second connecting shaft 3 is increased, and the stress at the joint of the two is reduced.
Preferably, as an implementation mode, a chamfer is provided at the front section of the insert block 31 to facilitate the insertion of the insert block 31 into the slot 21.
The working principle is as follows:
in a normal state, as shown in fig. 2, the connecting shaft I2 and the connecting shaft II 3 are connected together as a whole. When the bearing needs to be replaced, the screw rod 4 is unscrewed by a tool, and the screw rod 4 is separated from the first connecting shaft 2 and the second connecting shaft 3. Then, the second connecting shaft 3 is pulled, and the insert 31 and the slot 21 are separated from each other, so that the bearing 6 can be replaced.
