Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to an oil baffle mechanism for a speed reducer. Background Technology

[0002] As a key component of mechanical transmission, speed reducers are widely used in industries such as industrial automation, automotive, and transportation. Lubricating oil is an important working medium, effectively reducing wear on gears, bearings, and seals, and also playing a role in reducing impact and heat dissipation. However, during the actual operation of a speed reducer, the high-speed rotation of gears and bearings causes disordered splashing and flow of lubricating oil. If the flow of lubricating oil cannot be effectively controlled, it will lead to risks such as uneven lubrication and excessive oil churning losses. To solve these problems, traditional speed reducers usually have simple oil baffles or flat oil baffles installed near the bearings, but these structures have disadvantages such as poor oil blocking effect, inconvenient installation and maintenance, and poor adaptability.

[0003] With the continuous increase in power density of reducers, how to design efficient, reliable, and adaptable reducer oil baffles to achieve precise control of internal lubricating oil and improve transmission efficiency and service life has become a key issue that urgently needs to be addressed in this field.

[0004] Therefore, those skilled in the art are dedicated to developing an oil baffle mechanism for a high-efficiency, reliable, and highly adaptable reducer. Summary of the Invention

[0005] The purpose of this invention is to develop an oil baffle mechanism for a high-efficiency, reliable, and highly adaptable speed reducer.

[0006] The objective of this utility model is achieved through the following solution:

[0007] An oil baffle mechanism for a speed reducer includes a guide plate extending along the YZ plane, a baffle extending along the XZ plane at one end of the guide plate, an integrally formed downwardly extending oil guide groove at the bottom end of the guide plate, the bottom end of the baffle being partially closed to the upper end of the oil guide groove, a portion of the baffle extending into the oil guide groove, and the inclination angle of the oil guide groove being 10-30°; an arc-shaped recessed oil collection area is provided on the surface of the guide plate, the arc of the oil collection area being π / 18 to π / 6; and a speed reducer connecting mechanism is provided at the top of the guide plate.

[0008] Furthermore, the reducer connection mechanism includes a connecting plate welded to the top of the guide plate, and a fixing bolt is provided through the connecting plate.

[0009] Furthermore, the reducer connection mechanism also includes an elastic washer, which is clamped between the screw head of the fixing bolt and the connecting plate.

[0010] Further, the oil guide groove is composed of a flow guide plate and a guide plate, and the included angle between the flow guide plate and the guide plate is an acute angle.

[0011] The utility model discloses the advantages are:

[0012] 1. The oil baffle mechanism of the speed reducer is installed in the speed reducer and is used for collecting and guiding lubricating oil to the part needing lubrication, and the lubricating oil of the oil collection area is guided to the designated area lubrication by the baffle drainage area, which is efficient, reliable and adaptable.

[0013] 2. The arc range of the oil collection area can effectively avoid the condition that the oil collection area is warped and the kinetic energy of the oil is reduced due to the vertical impact of the oil on the oil collection area or the non-standard installation, and the oil collection and drainage efficiency is improved.

[0014] 3. The included angle between the flow guide plate and the guide plate is an acute angle, so that the collection of the lubricating oil is facilitated, and the lubricating oil is prevented from leaking out from the outside of the flow guide plate.

[0015] 4. The included angle between the flow guide plate and the guide plate is an acute angle, so that the kinetic energy of the oil is increased and the lubrication stroke is improved. BRIEF DESCRIPTION OF DRAWINGS

[0026] Example 1

[0027] like Figs. 1 to 3 As shown, an oil baffle mechanism for a speed reducer is installed inside the speed reducer for collecting lubricating oil. It includes a guide plate 1 extending along the YZ plane, a baffle 2 extending along the XZ plane at one end of the guide plate 1, and an integrally formed downward-extending oil guide groove 3 at the bottom end of the guide plate 1. A portion of the baffle 2 extends into the oil guide groove 3, and the bottom end of the baffle 2 is closedly connected to the upper end of the oil guide groove 3. The inclination angle of the oil guide groove 3 is α, which is 10–30°. An arc-shaped recessed oil collection area 4 is provided on the surface of the guide plate 1. The arc of the oil collection area 4 is b, which is π / 18–π / 6. This arc provides a buffer for the oil, preventing splashing and allowing the oil to flow smoothly into the oil guide groove 3. A speed reducer connecting mechanism 5 is provided at the top of the guide plate 1. The lubricating oil in the reducer is blocked by the guide plate 1 and flows along the oil collection area 4. Under the constraint of its arc range, it flows into the oil guide groove 3 without splashing. At the same time, due to the blocking effect of the baffle 2 and the inclination angle of the oil guide groove 3, the collected oil is prevented from flowing out from the other end, and the lubricating oil can quickly flow to the parts that need lubrication.

[0028] The oil collection area 4 effectively avoids the situation where the oil collection area is tilted up due to the oil being sprayed vertically towards it or improper installation, thus reducing the kinetic energy of the oil and improving the efficiency of oil collection and diversion.

[0029] In the embodiment, the speed reducer connecting mechanism 5 comprises a connecting plate 51 welded on the top of the flow guide plate 1, and the connecting plate 51 is provided with a fixing bolt 52; the speed reducer connecting mechanism 5 further comprises an elastic gasket 53 clamped between the screw head of the fixing bolt 52 and the connecting plate 51. The fixing bolt 52 is connected with the body of the speed reducer, so that the structure is installed in the speed reducer, and the elastic gasket 53 absorbs the vibration during the operation of the speed reducer, so as to avoid the loosening of the fixing bolt 52 due to the vibration. The speed reducer connecting mechanism 5 can be installed at any position of the speed reducer which needs to be lubricated through bolt connection.

[0030] The oil guide groove 3 can be an arc-shaped groove or a square groove, but in the embodiment, the oil guide groove 3 is an angle-shaped groove in order to simplify the structure, that is, the oil guide groove 3 is composed of a flow guide plate 31 and the flow guide plate 1, and the included angle between the flow guide plate 31 and the flow guide plate 1 is c, so that c is an acute angle, so as to facilitate the collection of the lubricating oil and avoid the leakage of the lubricating oil from the outside of the flow guide plate 31.

[0031] In addition, in the embodiment, the structure except the speed reducer connecting mechanism 5 can be integrally cast, so that the structure is simple and the cost is low.

[0032] The above only describes the preferred embodiments of the utility model, and is not used for limiting the utility model, and the changes made by the person skilled in the art to the utility model without departing from the spirit of the utility model all fall within the protection scope of the utility model.
