Description

Horizontal diesel engine

Technical Field

The utility model discloses a mechanical engineering and agricultural engineering, especially in the aspect of the agricultural machine.

Background

In general, agricultural work is carried out by using agricultural machines or vehicles to perform various modes of agricultural tasks, including cultivation, handling, or harvesting. These machines all require the starting of the engine as an engine to drive various parts of the machine. There are different types of engines depending on the suitability for mechanical and agricultural work.

The vast majority of the engines used in agricultural operations are diesel engines with vertically disposed pistons, or so-called vertical engines, but also other types of engines, such as horizontal engines with horizontally disposed pistons. Even horizontal engines are not as widely used as vertical engines, but are better suited for certain types of industrial work. And therefore more efficient in these particular applications than vertical type engines.

It is well known that the direction in which the pistons are placed is the main difference between vertical diesel engines and horizontal diesel engines. The above differences make the other components of the two types of engines very different in characteristics and configuration. Therefore, technical solutions applicable to vertical engines are generally not applicable to horizontal engines or at least not directly applicable to horizontal engines.

One of the limitations of horizontal diesel engines is related to the construction of the idler gear. The idle gear is generally designed with a plurality of connections to the crankcase (crankcase), the number and nature of which are considered to be critical in the technical field, for example provided with three points spaced apart, shaped like an equilateral triangle and fixed to a triangular member. The fixing in the above-described manner is based on the connection point being sufficiently stable for the idler gear to be fixed to the crankcase, so that the crankcase is provided with the above-described shape and function. In a general-purpose engine crankcase, some materials are less hard than others, and the idler gear of the above-described construction rotates during normal operation to cause friction against the crankcase. The friction of the crankcase as described above causes wear and deterioration of the crankcase, resulting in a problem of non-firmness. In the prior art, the above-mentioned friction is absorbed by placing a support washer, fired from a metallic material, between the idler gear and the crankcase. The idler gear in view of the above-described reasons must be composed of a plurality of parts using a specific material and a specific shape, resulting in high production costs. Furthermore, crankcase (crankcase) damage may result from the energy transmission process between the crankshaft gear and the idler gear (idler gear) via the coupling rotation. In the above two-gear structure, when rotating together, a force is applied in the direction of the crankcase, which is also one of the causes of wear of the crankcase.

Another limitation of horizontal diesel engines is related to the oil pan. For piston rod cranks, the oil in the oil sump of current horizontal engines is usually filled in a larger amount than necessary. The excess oil can affect the operation of the cam and connecting rod due to a number of factors, resulting in oil consumption. On the contrary, if the oil level is too low to reach the oil filter (oil filter), the oil distribution is not uniform, resulting in a drop in oil pressure and engine damage.

Therefore, there is a need to develop a horizontal diesel engine with a low cost, durable and efficient lubrication system.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to keep the durability and improve lubricating efficiency, provide the engine that has lower manufacturing cost.

In order to achieve the above object, an embodiment of the present invention provides a horizontal diesel engine, which includes a transmission mechanism and a housing. Wherein, drive mechanism includes: a main transmission element operatively engaged with the drive transmission element; and a sleeve into which the connecting member is inserted so that the transmission mechanism is fixed to the housing. Characterized in that the sleeve has an elongated configuration and has a flat surface covering one end of the sleeve and an opening for inserting a connecting element, the opening passing axially through the sleeve and the flat surface, the main transmission element comprising inclined teeth and engaging with the drive transmission element to direct the thrust outside the housing.

In view of the above embodiments, the transmission can be connected to the housing of the horizontal diesel engine, i.e. the sleeve and the connecting piece region, by a single mounting point. Therefore, the number of parts is greatly reduced. I.e. three fixation points are reduced to one fixation point. In addition, the sleeve and the connecting piece have a simple structure and shape. Therefore, the process of manufacturing the horizontal diesel engine according to the above embodiment is simple and less costly than the existing vertical diesel engine.

Furthermore, due to the above-mentioned direction of the drive transmission, the friction and the forces to which the sleeve is subjected are reduced, so that the wear of the sleeve is reduced, the service life of the housing can be increased, and the use of manufactured parts, such as collars (collar) necessary in horizontal diesel engines, is made unnecessary or improved.

In another embodiment of the present invention, the main transmission element is connected to the secondary transmission element, and the main transmission element and the secondary transmission element rotate simultaneously around the same axis.

According to the above described embodiment, the transmission element structure has two layers and rotates simultaneously, each layer for receiving and transmitting the forces used and being mounted to the engine. The activation device is connected to the secondary transmission element. When the engine starts to rotate, the secondary transmission element is caused to start to rotate along with the engine. In addition, the main transmission element also rotates. Therefore, the transmission element is connected and driven to drive the engine to continue running.

In an embodiment of the present invention, the flat surface is configured to engage with the pin to prevent the sleeve from rotating. According to the above characteristics, preventing the sleeve from rotating will help the connector and the sleeve to be able to firmly support the primary and secondary transmission elements. Further, the pin hole is preferable because it is easy to produce, does not require the use of more parts, and is also effective in preventing rotation.

In one embodiment of the present invention, the horizontal diesel engine further comprises a gasket disposed between the opening and the connecting member; the groove is arranged on the sleeve; and the protruding part is arranged on the gasket and is used for being clamped with the groove.

According to the above embodiment, the spacer will help support the assembly between the sleeve and the connection piece. In addition, the grooves on the sleeve and the protrusions on the shim are shaped and fittingly assembled together so that the shim does not rotate and the offset that exists between the components is reduced to ensure that the shim is properly installed on the sleeve, the grooves and protrusions shown matching each other.

If the primary drive element, the secondary drive element, the sleeve, the opening and the connecting piece are arranged coaxially aligned in the center of the sleeve. According to this feature, the above-mentioned components will be arranged to be combined into one set and only a central connection piece may be used.

In one embodiment of the invention, the main transmission element is operatively engaged with the counter transmission element. According to the above characteristics, the transmission mechanism can reduce the vibration of the engine by the transmission force.

The connection piece inserted into the sleeve may be a bolt (bolt), which is a simple part that can be produced or provided according to standards, facilitating production and replacement of parts.

In one embodiment of the present invention, the horizontal diesel engine is additionally provided with an inlet for adding lubricant to the engine compartment of the engine. The inlet is located at a predetermined level corresponding to the lubricant in the reservoir.

According to the above embodiment, when a user adds lubricant through the inlet of the reservoir, when the lubricant in the reservoir is at a suitable or preset level, the embodiment can prevent the user from adding too much lubricant at that level. Thus, excessive lubricant in the reservoir can be prevented from affecting the cam or connecting rod operation of the engine.

The utility model discloses an embodiment, horizontal diesel engine still has the filter that sets up in the apotheca. The filter is located at a predetermined height position such that a level of lubricant in the storage chamber reaches the filter when the horizontal diesel engine is inclined at a predetermined angle. According to the above characteristics, the filter is arranged at a position corresponding to the inclination value of the engine, so that the effective oil quantity can be kept during the operation and the acting force in the engine can be kept in a proper state.

Another embodiment of the utility model provides an agricultural machine, including above-mentioned horizontal diesel engine.

In the present application, various characteristics of the present invention may be presented in a range mode, and it is understood that the above range mode description is for convenience and rapidity, and the scope of the present invention should not be defined within a fixed range. Accordingly, the description of a range should be considered to include all sub-ranges and every value contained within its range. For example, a given number from 1 to 6 should be considered to have a meaning that includes subranges such as, for example, from 1 to 3, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as any single numerical value. E.g., 1, 2, 2.7, 3, 4, 5, 5.3, 6, etc. Moreover, the above considerations should be considered valid regardless of the breadth of the specified range.

The embodiments of the present invention will be described in detail with reference to fig. 1 to 5B as follows.

Fig. 1 shows a horizontal diesel engine 1, comprising a housing 11, or so-called crankcase (crank case), and a transmission 10, as well as structures relating to transmission elements, gears. The appearance shown in fig. 1 is focused on the transmission gear mechanism (idler gear). The transmission 10 has two main functions. The first function is to take up the force from the driver and transmit power to the crankshaft in order to assist in starting the device. Another function is to transmit the crankshaft rotation to a balancer shaft (balancer shaft) to reduce the vibration when the engine 1 is running.

The transmission 10 is designed to couple two transmission elements including a primary transmission element 12 or primary drive gear and a secondary transmission element 14 or secondary drive gear. The primary transmission element 12 and the secondary transmission element 14 are arranged on the same axis. In particular, the primary and secondary drive elements 12, 14 are fabricated as one piece. Thus, it can rotate coaxially with the intention of the invention.

Upon starting the engine, rotation is externally transmitted by a manual start, or start kit or the like, by a start gear 32 or Starter gear so that the main gear elements 12 begin to rotate together by being connected. Thereby, the drive transmission member 31 or the crank gear is driven. Finally, the crankshaft gear is driven to start the engine.

In operation, the crankshaft rotates and drives the drive transmission member 31 in sequence up to the primary transmission member 12 and the secondary transmission member 14; the main transmission element 12 engages and drives the adjusting balance transmission element 33 or the balance gear arrangement 33,33a,33 b. Finally, the both-side balancer shaft of the engine 1 is driven.

Fig. 2 shows the transmission mechanism 10 with the primary and secondary transmission elements 12, 14 arranged on the same axis, coaxial with the cylindrical shaft, or pivot or sleeve (sleeve) 16 supporting the primary and secondary transmission elements 12, 14.

As can be seen in connection with fig. 1, the main transmission element 12 has gear teeth 12a inclined to the left by about 15 degrees, the main transmission element 12 turning in a clockwise direction engaging with the gear teeth of the drive transmission element 31 rotating in a counter-clockwise direction. The teeth of the drive transmission element 31 are inclined to the right by about 15 degrees. By the engagement of the inclined gear teeth of the above-mentioned pair of transmission elements with each other, a force is generated in a direction away from the housing 11. This reduces the force acting on the housing 11, thereby preventing the housing 11 from being worn.

As shown in fig. 1 and 2, the primary drive element 12, the secondary drive element 14, the sleeve 16, the opening 18 and the connector 20 are disposed in coaxial alignment at a central location of the sleeve 16.

As shown in fig. 3, the sleeve 16 is mainly constituted by an elongated hollow cylindrical structure, each having a flat surface 17,17a with an opening 18 provided therebetween axially through the sleeve 16. The flat surface 17a side is provided with a groove 24, and the flat surface 17 side is provided with a pin hole (not shown in fig. 3).

The spindle or sleeve 16 is only used here as an example to describe the function of the component having the above-described functions and features. In general type work, the ordinary professional may replace the sleeve 16 with available components of similar efficacy, characteristics, such as, for example, a shaft (craft), rod (rod), bar or cylinder, to achieve a similar effect.

Referring to FIG. 2, one embodiment of the connector 20 is a bolt that is longer than the length of the sleeve 16, passing through the opening 18 along the sleeve 16 and the flat surface 17. Further, the thread 20a portion of the connector 20 is screwed to be fixed to the thread of the housing 11 or the crankcase (shown in fig. 1).

The flat surfaces 17,17a as surfaces, the respective sides of the sleeve 16 have different characteristics. The flat surface 17 side in contact with the housing 11 is provided with a pin hole 23 so that the pin 22 can be inserted. When the pin 22 is inserted into the pin hole 23, the sleeve 16 and the coupling member 20 are fixed to the housing 11 and thus do not rotate with the primary and secondary transmission members 12 and 14. The flat surface 17a on the other side is in contact with the washer 19, and the washer 19 separates between the flat surface 17a and the screw head 20b of the coupling member 20. Further, the flat surface 17a is provided with a groove 24, and the groove 24 is connected for penetration of a protruding portion 25 provided on the gasket 19 and protruding. Thus, it can be ensured that the spacer 19 is correctly attached to the side of the sleeve 16. The pin 22 and pin bore 23 are added for the purposes previously described, while the recess 24, which has different characteristics than the pin bore 23, is located on the other side of the sleeve 16.

Fig. 4A and 4B show the positions where the horizontal diesel engine 1, the storage room 81, and the inlet (inlet) 80 called an oil pan are provided. In this embodiment, the inlet 80 is an opening in the gear cover area that allows a user to add lubricant or oil to lubricate the internal equipment as part of the maintenance that should be performed. Oil should be added to an appropriate oil level 8la so as not to interfere with the operation of the cam 91 and the link 92. Typically, the inlet 80 is located above the storage chamber 81 and is provided with a suitable dipstick for reference by the user, who may or may not use the dipstick. Therefore, if the amount of oil added exceeds the amount required by the engine 1, the engine oil amount rises to the cam 91 and the link 92 that are in operation, which puts a greater burden on the engine 1.

The utility model discloses an in the embodiment, the entry 80 that adds machine oil is located the high region that engine oil predetermines to be fit for the operation of engine 1. The inlet 80 should be near the top of the storage compartment 81. Specifically, it should be in the head region of the bolt of link 92. According to this embodiment, if the amount of user-added oil exceeds an appropriate amount, oil will spill out of the inlet 80. Therefore, the user will not add oil more than an appropriate amount, and the engine 1 can operate at full efficiency.

Fig. 5A and 5B show an embodiment in which the horizontal diesel engine 1 and an oil filter (oil purifier) 82 are disposed inside the storage chamber 81. The horizontal diesel engine 1 shown in fig. 5A is inclined toward the piston head; the horizontal diesel engine 1 shown in fig. 5B is inclined toward the crankcase cover. The above-mentioned two-directional inclination may occur during operation.

The utility model discloses an among the embodiment, filter 82 is set up and predetermines the high position in locker room 80 to match with minimum machine oil level 81b in the horizontal direction. The horizontal diesel engine 1 is inclined to 20 degrees in the crankcase direction and 30 degrees in the crankcase direction. Therefore, when the diesel engine is inclined to the above two cases, the oil in the reservoir chamber 81 can be kept at its height at the minimum oil level 81b up to the filter 82. Specifically, the minimum oil level 81b of oil will correspond to about 3,245 cubic centimeters of oil in the storage chamber.

Another embodiment of the present invention provides an agricultural machine including the horizontal diesel engine 1 described above. Such agricultural machines may be agricultural vehicles, tractors or tractors, or the like.
