Description

Complete single row of the same kind of center wheel transmission

Technical field

The invention relates to a planetary gear transmission, specifically adopting no less than two rows of planetary rows, in which one row of planetary rows is a complete single-layer star planetary row, and the rest of the planetary rows are planetary rows of the same kind of center wheel. Yes, all through the control of the brakes to control the planetary gear transmission.

Background technique

In order to change torque and speed, many transmission systems are equipped with planetary gearboxes. The planetary row, planetary row structure, input and output locking ends, and controllers used in different planetary gearboxes have their own technical characteristics. The transmission structure of the existing planetary gearbox is complicated, and the control structure is complicated by controlling multiple disc clutches, brakes, and one-way clutches to shift gears. Previously, I invented and declared a planetary gear transmission that controls gears by controlling the brakes. The control structure is simple. It adopts a common planetary gear and a star-connected planetary gear structure. The transmission structure is relatively simple. The machinery industry needs a planetary gearbox with a simpler transmission structure and a simple control structure that controls the gears by controlling each brake. The present invention proposes such a planetary gear transmission.

The planetary gear transmission includes: the internal structure of each planetary row, namely the adopted planetary row, the structure formed by interconnecting the planetary rows, that is, the planetary row structure, the input and output lock ends, the controller of the transmission, etc.

Ordinary complete planetary row is composed of three parts: sun gear, inner gear ring and planet carrier with planetary gear. The axes of sun gear and inner gear ring are the central axis of planetary row. Sun gear is a kind of center wheel with inner teeth. The circle is another center wheel. Planetary rows are divided into single-layer star-planetary rows and double-layer star-planetary rows, each with its own laws of motion. The single-layer planetary row has only single-layer planetary wheels, and the number of planetary wheels is equal to the number of planetary wheel sets. From the inside to the outside of the complete single-layer planetary row, the sun gear meshes with the single-layer planet gear, and the single-layer planet gear meshes with the inner ring gear. The size of each component of the planetary row is enlarged and reduced in proportion, and its motion law remains unchanged. Multiple planetary rows are connected to each other to form a planetary row structure. A component in the planetary row structure is a rotating component with a rotation speed, and several components are connected to each other and have the same rotation speed, which is the same rotating component. The star-connected planetary row structure is: for multiple single-layer star planetary rows, the number of planetary wheel sets is the same, and the size of each planetary row is adjusted, and some are scaled up and some are scaled down. The distance between the axis of the middle planetary gear and the central axis of the planetary row is equal; align each planetary gear of the planetary row with the planetary gear axes of the adjacent planetary row and connect them in groups. This connection is called a star connection, and the star connection makes it participate in the connection. Each planetary wheel of has the same speed, and each planet carrier participating in the connection has another same speed. The planetary row structure formed by the star connection between the planetary rows is the star-connected planetary row structure. According to actual needs, each single-layer star planetary row in the star-connected planetary row structure can omit one of the two central wheels, the sun gear or the inner gear ring, to become an incomplete single-layer planetary planetary row. An incomplete single-layer star planetary row has only two components: a central wheel and a planet carrier with planetary wheels. The planetary rows used in the present invention: one row of planetary rows is a complete single-layer star planetary row, and the remaining planetary rows are incomplete single-layer star planetary rows and are the same kind of center wheel row. There are two types of the same type of center wheel row: the first type, each planetary row omits the inner ring gear, and is the same type of center wheel (sun gear) row. From the inside to the outside of the planetary row, the sun gear meshes with the single-layer planetary gear. In the second type, each planetary row omits the sun gear, and is the same kind of center wheel (inner gear) row. From the inside to the outside of the planetary row, a single-layer planetary gear meshes with the inner gear.

Summary of the invention

In order to design and manufacture a planetary gear transmission with a simpler transmission structure and a simple control structure for controlling gears by controlling the braking of each brake, the present invention proposes a complete single row of the same center wheel transmission. Features include the planetary row, planetary row structure, input and output locking ends, and various brakes. The characteristics are as follows:

The planetary row used is: the present invention adopts no less than two rows of planetary rows, one of which is a complete single-layer planetary row, and the other planetary rows are the same kind of center wheel row. The same kind of center wheel row includes the same kind of center wheel (sun gear) row and the same kind of center wheel (inner gear) row. Each planetary row in which the same kind of center wheel is a sun gear is called the same kind of center wheel. (Sun gear) row, each planetary row in which the same kind of center wheel is an inner ring gear is called the same kind of center wheel (inner gear ring) row. In the present invention, one of the transmissions is selected and used to form a transmission with a complete single-layer planetary row, and the same kind of center wheel (sun gear) row and a complete single-layer planetary row are selected to form a complete single row of the same kind of center wheel (Sun gear) platoon transmission; select the same kind of center wheel (inner gear ring) row and a complete single-layer star planetary row to form a complete single row of the same kind of center wheel (inner gear ring) row transmission. In the present invention, the concept of "planetary row" includes the components of the planetary row and the parts of the components, including the components, the meshing, transmission, support, arrangement and positional relationship between the components, including the components, the structure of each component, omission and parameter settings.

The planetary row structure is a star-connected planetary row structure. The star-connected planetary row structure is: for multiple single-layer star planetary rows, the number of planetary gear sets is the same, and the size of each planetary row is adjusted until the axis of a certain layer of planetary gears in each planetary row is between the central axis of the planetary row The distances are equal; each planetary wheel in the planetary row is aligned with the planetary wheel axis of the adjacent planetary row and connected in groups. This connection is called a star connection. The planetary row structure formed by the star connection between the planetary rows is The star connects the planetary row structure. The planet carrier of each planetary row in the star-connected planetary row structure together becomes a rotating component, and the center wheel of each planetary row is a rotating component. In the present invention, "planetary row structure" is a specific term, and its concept includes the connection between the planetary rows, and also includes the planetary rows in connection and the components and parts of the planetary rows in connection, such as planetary rows, Such as rotating components, planetary gears participating in star connection, etc.

The input and output lock ends are: use the planet carrier as the input end to connect to the power device; any center wheel as the output end to connect to the power use equipment; the other center wheels are each used as a lock end and connected to a brake, which is controlled by the shift control device control. Control a brake to brake to lock the center wheel connected to it, and the rotation speed of the center wheel is zero; control a brake to stop the center wheel without braking. In conjunction with the planetary row, four types of combinations are often used for the input and output locking ends: the first combination is: a complete single row of the same center wheel (sun wheel) row. The planet carrier is used as the input end, one sun gear is selected as the output end in each planetary row, and the remaining sun gear and the ring gear are each used as a locking end. The second combination is: a complete single row of the same kind of center wheel (sun wheel) row. Take the planet carrier as the input end, each sun gear as a locking end, and the inner gear ring as the output end. The third combination is: a complete single row of the same kind of center wheel (inner gear ring) row. The planet carrier is used as the input end, an inner ring gear is selected as the output end in each planetary row, and the remaining inner ring gear and the sun gear are each used as a locking end. The fourth type of combination is: a complete single row of the same kind of center wheel (inner gear ring) row. Take the planet carrier as the input end, each ring gear as a locking end, and the sun gear as the output end.

Each brake is: the present invention adopts no less than two brakes as the controller of the transmission, and each is connected with a lock end. Brakes are mature technologies, such as mechanical brakes, electromagnetic brakes, and power-assisted brakes. The brake includes a stator and a mover, the stator is connected with a fixed object, and the mover is connected with a locking end, which can be controlled to be in a braking state, a half braking state and a non-braking state. According to mechanical principles, a clutch with one end connected to a fixed object such as a base is also a brake.

In the star-connected planetary row structure of the present invention, each rotating component serves as an input and output locking end, and no rotating component is redundant, which shows that the transmission structure of the present invention is simple. Ordinary complete planetary row assembly can only be assembled axially, which has a certain contradiction with the structure of star-connected planetary row, and assembly is difficult. Since the present invention adopts more incomplete single-layer star and planetary rows, each incomplete single-layer star and planet can be assembled radially after eliminating the axial assembly, and the axial assembly is adopted when the complete planetary row is finally assembled. This expands the assembly method of the planetary gearbox, and the assembly is simple. Ordinary planetary gearboxes shift gears by controlling multi-disc clutches, brakes, and one-way clutches, and use hydraulic control mechanisms for actuation, with complex control structures. In the present invention, the gear position is controlled entirely by controlling the brake, the hydraulic control mechanism may not be used, and the control structure is simple.

The operating characteristics of the transmission of the present invention are: control a brake to brake to make the speed of the center wheel connected to it be zero; when the input speed is input, control a brake to brake, the output must form an output speed, and the input speed constitutes a certain The transmission forms a transmission ratio corresponding to a gear; when the other brake is controlled, the output end must form another output speed, which forms another certain proportional relation with the input speed. The transmission forms another transmission ratio, corresponding Another gear; and so on, the transmission of the present invention controls the gear by controlling the braking of each brake. When one brake is controlled to brake in half, the transmission is semi-linked in the corresponding gear; when all brakes are controlled to not brake, the transmission is in neutral; when two or more brakes are controlled to brake, the transmission stops. The transmission ratio is the ratio of the input rotation speed to the output rotation speed. When the transmission ratio is a positive value, the input rotation speed and the output rotation speed have the same direction, and when the transmission ratio is a negative value, the input rotation speed and the output rotation speed are opposite.

The direct connection means that the rotational speeds of the connected objects are the same through mechanical connection, and the indirect connection means that the rotational speeds of the two driven objects are deterministically related through mechanical transmission. Separate "connection" generally refers to direct connection, and indirect connection will be specifically stated. In each planetary row, the relationship between the planet carrier and the planet wheel is: one is the shaft and the other is the bearing. The number of gear teeth of each component in each planetary row is determined according to actual needs, and the gear modulus of each component of the planetary row does not have to be the same as that of other planetary rows. There are two types of connection between the input end and the power unit: direct connection and indirect connection through the side shaft gear; the connection between the output end and the power use equipment includes direct connection and indirect connection through the side shaft gear; the direct connection transmission ratio is 1.0, The indirect transmission ratio is generally negative, such as -1.0. The power plant adopts mature technologies, such as electric power plant, steam power plant, and fuel power plant. The shift control device adopts mature technology, such as an electric control mechanism, a mechanical control mechanism or a hydraulic control mechanism. The multi-layer quill shaft is a mature technology. The bearing and the shaft and the shafts of each layer can rotate relative to each other, but do not slide relative to each other in the axial direction. Each bearing is a mature technology. The bearing supports the shaft. The bearing and the shaft can rotate relative to each other, but they do not slide relative to each other in the axial direction. The brake is a mature technology. The gear shift control device of the transmission of the present invention is actuated by the stator of the brake, and a hydraulic control mechanism is not necessary. The multi-plate clutch is a mature technology. In the traditional transmission, the multi-plate clutch contains two independent movers. Since the shift control device is actuated by the movers, a hydraulic control mechanism must be adopted. The hydraulic control mechanism is a kind of shift control device and has a complicated structure.

The bearings in each figure only indicate the supporting principle, and do not reflect the actual number and actual size of the bearings.

The number of gears of the transmission of the present invention is equal to the number of brakes, which is equal to the number of planetary rows. Therefore, the number of planetary rows is specifically set according to the actual required gear number of the transmission. The transmission ratio of each gear of the transmission of the present invention depends on the number of central gear teeth and the number of planetary gears of the complete single-layer star planetary row and each incomplete single-layer planetary planetary row. Therefore, each gear transmission ratio is specifically set according to actual needs. The number of central gear teeth and planetary gear teeth of the planetary row. The number of planetary gear sets is specifically set according to the actual torque to be transmitted by the transmission and the number of teeth of each central gear. The transmission obtained through these specific settings does not change the characteristics of the present invention, and all belong to the protection scope of the present invention. The structural diagrams of the transmission of the present invention with no more than four rows of planetary rows are shown in Figs. 1 to 12, and the specific arrangement is demonstrated in each embodiment. The structure diagram of the transmission of the present invention with more than four planetary rows can be deduced by analogy, and its specific settings can be deduced by analogy according to these embodiments, and will not be described in detail.

A transmission, when keeping all other structures unchanged, only swaps its input end and output end, the new transmission formed is the reverse transmission of the original transmission. The number of gears of the reverse transmission remains unchanged, and the new gear ratio of the reverse transmission is the reciprocal of the original gear ratio of the original transmission. The characteristics of the reverse transmission of the transmission of the present invention are: the planetary row used is unchanged, the planetary row structure is unchanged, the brakes are unchanged, the input and output locking ends are changed to: use the planet carrier as the output end to connect the power use equipment, any one The center wheel is used as the input end to connect to the power unit, and the other center wheels are each used as a locking end and connected to a brake; the four types of combinations often used for input and output locking ends are changed to: the first combination is: a complete single row of the same center The wheel (sun gear) row, with the planet carrier as the output end, select one sun gear as the input end in each planet row, and the rest of the sun gear and ring gear as a locking end; the second type of combination is: a complete single row The same kind of center wheel (sun gear) row, with the planet carrier as the output end, each sun gear as a locking end, and the inner ring gear as the input end; the third combination is: a complete single row of the same kind of center wheel (inner Ring gear) row, the planet carrier is used as the output end, one inner gear ring is selected as the input end in each planetary row, and the other inner ring gear and sun gear are each used as a locking end; the fourth combination is: a complete single row The center wheel (inner gear ring) row uses the planet carrier as the output end, each inner gear ring as a locking end, and the sun gear as the input end; its operating characteristics remain unchanged. The reverse transmission of the transmission of the present invention also belongs to the protection scope of the present invention.

The features of the planetary row, the structure of the planetary row, the input and output locking ends, and the characteristics of each brake, as well as the operating characteristics and the reverse transmission characteristics adopted above are the innovations of the present invention.

The planetary row used is: the present invention adopts no less than two rows of planetary rows, one of which is a complete single-layer planetary row, and the other planetary rows are the same kind of center wheel row, and the same kind of center wheel planetary row includes the same There are two kinds of center wheel (sun gear) planetary row and the same kind of center wheel (inner gear ring) planetary row. Each planetary row in which the same kind of center wheel is a sun gear is called the same kind of center wheel (sun gear) planetary row. Each planetary row in which the same kind of center wheel is an inner ring gear is called the same kind of center wheel (inner gear) planetary row. The present invention selects one of them in a transmission to form a transmission with a complete single-layer planetary planetary row. Select the same kind of center wheel (sun gear) planetary row and a complete single-layer star planetary row to form a complete single row of the same kind of center wheel (sun gear) planetary row transmission, select the same kind of center wheel (inner gear) planetary row and one A complete single-layer star planetary row forms a complete single-row planetary gear transmission of the same kind of center wheel (inner gear ring);

The planetary row structure is a star-connected planetary row structure. The star-connected planetary row structure is: for multiple rows of single-layer star planetary rows, the number of planetary wheel sets is the same, and the size of each planetary row is adjusted until the planets in each planetary row The distances between the wheel axis and the center axis of the planetary row are equal. Align each planetary wheel in the planetary row with the planetary wheel axis of the adjacent planetary row and connect them in groups. This connection is called a star connection. The planetary row structure formed by the way of connection is the star-connected planetary row structure;

The input and output locking ends are: the planet carrier is used as the input end to connect to the power device, any center wheel is used as the output end to connect to the power use equipment (the description is inaccurate. It has been changed), and the remaining center wheels are each connected as a locking end. The brakes are controlled by the shift control device; each brake is: the present invention uses no less than two brakes as the controller of the transmission, each connected to a lock end, the brakes can be controlled to be in a braking state or a semi-braking state And non-braking state.
