Abstract

The utility model discloses a bidirectional driver oil lubrication pump, which comprises a pump body, a central axle, a tooth sleeve, an inner tooth sleeve, and an end cover. The pump body is mutually connected with the end cover through a bolt, a flange hole and oil inlet and outlet holes are arranged on the pump body, the tooth sleeve and the inner tooth sleeve are mutually matched and arranged together on the central axle passing through the pump body, and an eccentric sleeve is sleeved on the periphery of the inner tooth sleeve. When the rotation of a drive source changes, the lubrication pump realizes the constant invariable bidirectional driving pump oil of inlet and outlet oil ways, and the lubrication pump has the advantages that the structure is compact, the weight is light, the installation is convenient, the self-priming performance is good, the efficiency is high, the flow rate is stable, and the noise is low, etc.

Description

Bi-directional drive oil lubricating pump

Technical field

The utility model relates to a kind of lubricant pump, a kind of more precisely bi-directional drive oil lubricating pump.

Background technique

Existing various mechanical device is in order to improve transmission efficiency, to simplify driving mechanism, in design, selected the kind of drive of energy clockwise and anticlockwise more and more for use, in the case, originally the structural type of lubricant pump will realize the bi-directional drive fuel feeding, need the outer oil circuit of pump is adjusted, its complex structure, operation inconvenience, needs that can not the adaptive technique progress.

The model utility content

At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of oil lubricating pump of bi-directional drive.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of bi-directional drive oil lubricating pump, comprise the pump housing, axle, tooth cover, internal tooth casing and end cap, the pump housing is connected with end cap by bolt, offer flange hole and turnover oilhole on it, the tooth cover matches with internal tooth casing and is arranged on the axle of passing the pump housing, and described internal tooth casing outer race is equipped with eccentric bushing.

Described eccentric bushing offers semi-circular groove on its outer peripheral surface.

Described tooth cover has two circular arc sinusoidal curve profiles of tooth, and the shape of internal tooth casing is suitable with it.

The utility model has increased eccentric bushing on the basis of existing oil lubricating pump, when motor rotation, can carry out pump oil by the tooth cover and the rotation that is meshing with each other of internal tooth casing, when motor commutation, the tooth cover drives internal tooth casing and rotates, and then drive the deflection of eccentric interplanting 0～180 degree, realize that inlet and outlet of fuel channel is changed automatically in the pump, need not to change under the situation of outside oil circuit, the work of pump oil is proceeded, realize bi-directional drive pump oil, have compact structure, in light weight, easy for installation, self-priming performance is good, efficient is high, stability of flow, low noise advantages.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1---the pump housing

2---axle

3---the tooth cover

4---internal tooth casing

5---end cap

6---bolt

7---oilhole

8---eccentric bushing

9---semi-circular groove

10---bi-directional drive oil lubricating pump

Extremely shown in Figure 7 as Fig. 1, this bi-directional drive oil lubricating pump mainly is made up of the pump housing 1, axle 2, tooth cover 3, internal tooth casing 4 and end cap 5, the pump housing 1 is connected with end cap 5 by bolt 6, offer flange hole and turnover oilhole 7 on it, tooth cover 3 matches with internal tooth casing 4 and is arranged on the axle 2 of passing the pump housing 1, tooth cover 3 has two circular arc sinusoidal curve profiles of tooth, the shape of internal tooth casing 4 is suitable with it, the outer race of internal tooth casing 4 is equipped with eccentric bushing 8, this eccentric bushing on its outer peripheral surface, offer semi-circular groove 9.

The working principle of this bi-directional drive oil lubricating pump is: the tooth cover 3 on the axle 2, internal tooth casing 4 is meshing with each other, tooth cover 3 is rotated by driven by motor, internal tooth casing 4 rotates because of engagement, when two teeth separate gradually, the volume of working space increases gradually, form partial vacuum, machine oil is under atmospheric effect, be inhaled into lubricant pump, the machine oil that sucks is extruded release along pump housing inwall, when tooth cover 3, internal tooth casing 4 constantly rotates, lubricant pump just constantly sucks and discharges machine oil, when motor rotation, rotate with being meshing with each other of internal tooth casing 4 and cooperating of eccentric bushing 8 can carry out pump oil by tooth cover 3, when motor commutation, tooth cover 3 drives internal tooth casing 4 and rotates, and then drive eccentric bushing 8 is done the deflection of 0～180 degree, rotation by eccentric bushing realizes the invariable bi-directional drive pump of inlet and outlet of fuel channel oil, two circular arc sinusoidal curve profiles of tooth add sinusoidal curve by two circular arcs and are combined into profile of tooth, it between two contacting profiles a line Continuous Contact, the flank profil face does not have slide relative, therefore the flank of tooth does not have wearing and tearing, running steadily, there is not the liquid phenomenon of being stranded, and noise is low, life-span is long, the efficient height, thoroughly solved the lubricant pump vibration, noise, phenomenons such as bearing load is big can be widely used in iron and steel, oil, petrochemical industry, metallurgical, chemical fibre, machinery, glass, industries such as pharmacy.

As shown in Figure 8, this bi-directional drive oil lubricating pump 10 is paid in the case at the TX-25 milling head and is used, after milling head adopts bi-directional drive oil lubricating pump, can satisfy cutterhead on positive and negative both direction during milling transmission part can normally lubricate, and need not any adjustment is done by system, effect is obviously reliable.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; though but on its shape or structure, do any variation, every identical with the utility model or akin technological scheme is all within its protection domain.
